Step-by-step explanation:

Well c in this case is total

h is the amount of boxes

Since each box (h) cost $1.25 each, you multiply 1.25 by h.

Then that one time coupon off his total would be just -0.50

Four fewer than triple the sum of x and 3 is 17

Answers

Answer:

4- 3(x -3) =17 x =10

Step-by-step explanation:

We are going to start with the sum of x and 3. You can write that like this : x+3. Then, it says “triple the sum of x and 3”. That would be 3(x+3). Then it says “four fewer”. So that is 3(x+3)-4. And all of that equals to 17. So the equation is 3(x+3)-4=17.
Then to solve that, we are going to add 4 to both sides. So now our equation looks like 3(x+3)=21. Then divide by 3 on both sides. (x+3)=7. Subtract 3 on both sides. x=4.

What is the equation of the following line? ​

Answers

Answer:

E

Step-by-step explanation:

y = mx + b

m = slope

b = y-intercept

slope = rise / run = 7 / 1 = 7

m = 7

y-intercept = 0

So:

y = 7x + 0

y = 7x

Option C

Step-by-step explanation:

The two triangles will be similar if the ratio of their corresponding sides are proportional. Let's check this ,

1st side :-

= 8:3

2nd side :-

= 10 : 4 = 5:2

3rd side :-

= 6:5 .

Since the ratio of the sides of triangle are not same therefore that 2 triangles are not similar .

Option C is correct .

Find the value of x for ABCD is a parallelogram

Answers

Find parallelogram ABCD attached

Answer:

x = 3

Step-by-step explanation:

In parallelograms, the diagonals typically divide each other into 2 equal parts.

This means that from the attached parallelogram, we can say that;

4x - 6 = 2x or 6x - 15 = x

Thus;

4x - 2x = 6

2x = 6

x = 6/2

x = 3

Let's confirm with the second equation;

6x - x = 15

5x = 15

x = 15/5

x = 3

Answers

Answer:

Many people rush into relationships, whether it be romantic or friendly. No matter the kind of relationship, the number one thing you want to make sure you have is boundaries. When you get to know someone, you have to make sure they respect your beliefs, your boundaries, and won't peer pressure you into doing anything. You also want to make sure the person you are getting to know is getting to know you for you and not anything else. It has been proven that the more happy relationships and healthy relationships we have, the longer we live. But it also works the other way around. That's why we have to make sure we surround ourselves with the right kinds of people otherwise, we'll just end up getting hurt. It's very common for people to be influenced by outside forces and, therefore, hurt us and turn around and instead of being our loved ones, they're our enemies. That's why we have to make sure we choose the right kinds of people.

Cos(x+y)cos(x-y)=cos^2y - sin^2x

Answers

cos(x + y) cos(x - y) = (cos(x) cos(y) - sin(x) sin(y)) (cos(x) cos(y) + sin(x) sin(y))

… = (cos(x) cos(y))² - sin(x) sin(y) cos(x) cos(y) + sin(x) sin(y) cos(x) cos(y) - (sin(x) sin(y))²

… = (cos(x) cos(y)) - (sin(x) sin(y))²

… = cos²(x) cos²(y) - sin²(x) sin²(y)

… = (1 - sin²(x)) cos²(y) - sin²(x) sin²(y)

… = cos²(y) - sin²(x) cos²(y) - sin²(x) sin²(y)

… = cos²(y) - sin²(x) (cos²(y) + sin²(y))

… = cos²(y) - sin²(x)

Hector puts together two tables to make a long table for a class picnic.
One table is 7 feet 7 inches long. The other table is 6 feet 9 inches long.
What is the total length of the two tables?

Answers

Answer: 14 feet 4 inches

Step-by-step explanation:

Given: The length of the first table = 7 feet 7 inches

The length of the second table = 6 feet 9 inches

The total length of two tables = 7 feet 7 inches + 6 feet 9 inches

= (7+6) feet (7+9) inches

=13 feet 16 inches

Since 1 feet = 12 inches

The total length of two tables = 13 feet+ (12 inches +4 inches)

=13 feet +( 1 feet +4 inches)

= 14 feet 4 inches

Hence, the total length of the two tables =  14 feet 4 inches

Two groups of school children had their forearm lengths measured. Dot plots are provided showing these results.


a
Group Y. There were 6 children who had a forearm length that measured longer than 12 inches.

b
Group X. There were 4 children who had the lowest forearm length of 10 inches in this group.

c
Group X. None of the children in this group had a forearm length longer than 12 inches.

d
Group Y. One child in this group had the smallest forearm length of 10 inches.

Answers

Answer:

Stament a, b, and c are correct.

Statement d is INCORRECT.

Step-by-step explanation:

Based on the dot plots given, the following statements are true and correct:

✔️Statement A is correct

Rationale: in the dot plot representing group Y, there are 6 dots on number 13. These shows that 6 children have an arm length of 13 inches. This means that there are actually 6 children who had a forearm length that measured longer than 12 inches.

✔️Statement b is correct:

Rationale: the lowest forearm length displayed on the dot plot for group X is 10 inches, represented by 4 dots.

✔️Statement c is correct:

Rationale: the dot plot for group X shows that the maximum arm length recorded for group X was 12 inches. Therefore no child in group X has a forearm length that is longer than 12 inches.

❌Statement d is NOT CORRECT

Rationale: the dot plot for group Y shows that 2 children had the smallest forearm length of 11 inches.

what is the value of x ?

Answers

Answer:

Since we know that the sum of the two angles equal 180, we can add them together to equal 180 degrees.

2x+10+x+26=180

Combine like terms.

3x+36=180

Subtract 36 from both sides.

3x=144

Divide 3 from both sides.

x=48
