im not sure if im correct so i would double check but either way have a great day dont let anyone or anything bother you. and be positive

Answer 2

Answer: trueStep-by-step explanation:When combining fractions with a variable, you should first convert the fractions to decimals, add the decimals, include the variable, and then convert the decimals back to fractions or, occasionally, mixed fractions.

what's a fraction?Any number of equal parts is represented by a fraction, which also represents a portion of a whole. A fraction, such as 1/2, 8/5, or 3/4, indicates how many components of a particular size there are when stated in ordinary English.

Answers

Answer:

Step-by-step explanation:

so its 23 cause .

supplementary means that the two angles must add up to 180 degrees.

that means we should set up the equation like this:

(x+4)+(2x-7)=180

solve by adding like terms

3x-3=180

add

3x=183

divide

x=61

we can check this answer by plugging the number back in.

(61+4)+(2(61)-7)=180

(65)+(115)=180

therefore angle A would equal 65 degrees.

Ms. Hernandez is taking her children and their friends to the movies. She will pay $10 for her adult ticket and $7 for each child ticket. Ms. Hernandez does not want to spend more than $40. Which inequality can be used to find c, the number of child tickets Ms. Hernandez can purchase?

Answers

Answer:

The inequality can be used to find c, the number of child tickets Ms. Hernandez can purchase is option (D) 10 + 7x ≤ 40.

Step-by-step explanation:

Step 1: Let x be the number of child tickets that Ms. Hernandez can purchase.

Step 2: The cost of the adult ticket is $10, and the cost of each child ticket is $7. Therefore, the total cost T of the tickets can be expressed as:

T = 10 + 7x

Step 3: Ms. Hernandez does not want to spend more than $40. So, we can write an inequality to express this:

T ≤ 40

Substituting the expression for T, we get:

10 + 7x ≤ 40

Simplifying the inequality:

7x ≤ 30

Step 4: Dividing both sides by 7:

x ≤ 4.2857

Since we cannot purchase a fraction of a ticket, Ms. Hernandez can purchase at most 4 child tickets.

Therefore, the inequality that can be used to find c is:

7x + 10 ≤ 40 or 10 + 7x ≤ 40.

The owner of a tea shop is making a blend of two teas. Tea A costs $5.40 per pound. Tea B costs $6.80 per pound. The owner wants to make 8 pounds of the blend and wants to sell it for $5.75 per pound. How much of each tea should he use?

Answers

Answer:
12 pounds of tea-1 and 8 pounds of tea-2 should be used.
Step-by-step explanation:
Let the mass of the tea-1 be x and tea-2 be y.
Total mass of mixture tea owner wants to make = 20
pounds
x+y = 20 ... [1]
Cost of 1 pound of tea-1 = $6.50
Cost of 1 pound of tea-2 = $4.00
Cost of the 1 pounds mixture = $5.50
₴ × $6.50 + y × $4.00 = 20 × $5.50
6.5× + 4.00y = 110... [2]
Solving equation [1] and [2] by substitution method, putting value of × from [1] in [2].
X=20 - y
6.5(20 - y) + 4.00y = 110
130 - 6.50y + 4.00y = 110
-2.5 y=-20
y = 8
×=20-y = 20-8 = 12
12 pounds of tea-1 and 8 pounds of tea-2 should be used.

Kevin goes to a restaurant that offers 4 appetizer choices, 4 different meats, 6 vegetables, 4 desserts, and 7 drinks. Assuming he gets one of each, how many different meals could he order? Responses A 184 B 25 C 2688 D 672 E 504

Answers

Kevin has 4 choices of appetizers, 4 choices of meats, 6 choices of vegetables, 4 choices of desserts, and 7 choices of drinks. To find the total number of different meals he can order, we need to multiply the number of choices for each category:

4 appetizer choices × 4 meat choices × 6 vegetable choices × 4 dessert choices × 7 drink choices = 2,688

Therefore, Kevin can order 2,688 different meals. So the answer is option C.

the correct answer is 2688 because if you do 4 x 4 x 6 x 4 x 7, it’ll equal to 2,688.

The scale on a map reads 4 cm = 1.6 m. The relationship on the map is graphed on a coordinate grid, with centimeters on the y -axis and meters on the x -axis. The rate of change is: blank blank per blank

a. 0.4
b. 2.5
c. centimeters
d. meters

Answers

Answer:

To find the rate of change, we need to determine how much the value on the y-axis changes for every unit change on the x-axis.

The scale on the map reads 4 cm = 1.6 m, which means that for every 1 meter on the x-axis, there are 2.5 centimeters on the y-axis (since 4 cm is equivalent to 1.6 m, we can divide both sides by 1.6 to get 1 cm is equivalent to 0.4 m, or 2.5 cm is equivalent to 1 m).

Therefore, the rate of change on this graph is:

2.5 centimeters per meter

Or, we can express this as:

2.5 cm/m

Answer:

∡4 = 146°

Step-by-step explanation:

First, we need to find the value of ∡2, and keep in mind that the sum of all the angles in a triangle is = 180°.

Since the triangle is a right angle, we know that the angle to the bottom right = 90°. The other angle is 56°.

Since there are only 3 angles, let's add 56° and 90° to find ∡2.

56 + 90 = 146

180 - 146 = 34°

∡2 = 34°.

Now that we've found ∡2, we need to find out what type of angles ∡4 and ∡2 are.

They are supplementary angles, since they add up to 180°.

Let's subtract 180 - 34 to give us the value of ∡4

180 - 34 = 146

Therefore ∡4 = 146°

Answer:

∡4 = 146°

What is the equation for the line of reflection? On a coordinate plane, image A B C D has points (2, 2), (7, 3), (5, 1), (4, 1). Image A prime B prime C prime D prime has points (10, 2), (5, 3), (7, 1), (8, 1). x = 6 y = 6 y = x y = 2 Mark this and return

Answers

The equation of the line of reflection should be .

Given information:

Triangle ABC has points (6, 3.7), (5.4, 2), (1, 3). Triangle A' B'C' has points (3.7, 6), (2, 5.4), (3, 1).

A'B'C' is the reflection of the triangle ABC.

It is required to find the equation of the line of reflection.

Now, from the given coordinates of triangle ABC and its reflection, it is clear that the x and y-coordinates have interchanged their values. For example, coordinate (6,3.7) has become (3.7,6).

Therefore, the equation of the line of reflection should be .

To find the equation for the line of reflection, we need to find the midpoint between each point and its corresponding point in the reflected image. Then, we can find the equation of the line that passes through each pair of midpoints.

The midpoint between (2, 2) and (10, 2) is ((2 + 10) / 2, (2 + 2) / 2), which simplifies to (6, 2). The midpoint between (7, 3) and (5, 3) is ((7 + 5) / 2, (3 + 3) / 2), which simplifies to (6, 3). The midpoint between (5, 1) and (7, 1) is ((5 + 7) / 2, (1 + 1) / 2), which simplifies to (6, 1). Finally, the midpoint between (4, 1) and (8, 1) is ((4 + 8) / 2, (1 + 1) / 2), which simplifies to (6, 1).

The line of reflection is the line that passes through each pair of midpoints. Since all four midpoints have the same x-coordinate of 6, the line of reflection is a vertical line passing through x = 6.

Therefore, the equation for the line of reflection is:

x = 6

Answer: yeah 56

42.5 divided by .75 is 56.666666666666666666666666666667

And with this type of question, you have to round down to a whole number so, 56

Hope this helps :)

hey! 42 1/2 inches is 85/2 inches.

to find the number of books she can fit on the shelf, she has to divide the total amount of inches (85/2) by the width of each book (3/4)

dividing by a fraction is the same thing as multiplying by its reciprocal, so… 85/2 x 4/3 = 170/3

170/3 = about 56 books (rounded to the nearest whole number)

Step-by-step explanation:

[tex] < 2 = 180 - 109 \\ = 71 \\ < 1 = 180 - 71 - 55 \\ = 54[/tex]

The measure of ∠1 is 54 degrees by angle sum property

We have to find measure of angle 2 before finding angle 1 ∠1

∠2 + 109 = 180

Subtract 109 from both sides

∠2 = 180-109

∠2 =71 degrees

From angle sum property theorem we know that in any triangle the sum of angles is 180 degrees

∠1 + 71 +55 = 180

∠1 + 126 =180

Subtract 126 from both sides

∠1 = 180-126

One hundred eighty minus one hundred twenty six is equal to fifty four degrees

∠1 = 54 degrees

Hence, the measure of ∠1 is 54 degrees by angle sum property

68.50x + 127.95 = 675.95

Answers

Answer: Option B

Step-by-step explanation:

Considering Option A

we can infer that the office manager paid a total of $675.95

the cost of the software package is $68.50

while an employee is paid $127.95 every hour she works on the website

So, the equation for this situation goes like this: 68.50 + 127.95x = 675.95

Coming to Option B

we can infer that the office manager paid a total of $675.95

the cost of one monitor is $127.95

while the hard drives are for $68.50 each

So, the equation for this situation goes like this: 68.50x + 127.95 = 675.95
