What is the positive solution to this equation?

4x2 + 12x = 135

Answer:

50

Step-by-step explanation:

Angle 1 is inside a triangle. Angles in a triangle add up to 180.

Angle 1 = 180 - 90 - 40 = 50.

Angle 2 is on a straight line (180 degrees), shared with angle 1. Therefore, angle 2 is 180 - Angle 1 = 130. Angle 3 and 4 can be calculated the same way Angle 2 was calculated (1=3, 2=4).

Angle 5 is 180 - 90 - Angle 3 which is 180-90-50 which is 40.

Angle 6 is 180 - Angle 5 = 180 - 40 = 140.

Angle 8 is the same as Angle 6

Finally, Angle 7 is 180-90 = 90.

.3, 1/3, 2/5, 1/2, .6

Answer:

0.3, 1/3, 2/5, 1/2, 0.6

Step-by-step explanation:

Divide 1 by 3 and you get 0.333. Divide 1 by 2 and you get 0.5. Then divide 2 by 5 and you get 0.4. From there it's easier to compare. You could also make the decimals into fractions, but comparing those would take more steps by trying to find similar denominators.

A. 8, 14, 20, 26

B. (1, 8), (3, 14), (5, 20), (7, 26)

C. As x increased by 2, g(x) increased by 6. If x increases by 1, g(x) will increase by 3.

Hope this helped.

Answer:

No

Step-by-step explanation:

No, (-5, -4) is not a solution to the system of equations. In order for a point to be a solution to a system of equations, the lines have to intersect at that point in a graph. Looking at the given graph, the lines do not intersect at (-5, -4), but at (-4, -5) instead. Thus, (-5, -4) is not a solution.

Complete question :

When the monarch butterfly is migrating to the south, it has an average speed of 80 miles per day. Write an equation that shows the realtionship between the number of days (t) and the distance (in miles) it has traveled (d)

Answer:

d = 80t

Step-by-step explanation:

Given :

Average speed = 80 miles per hour

Distance traveled (in miles) = d

Number of days = t

Equation which shows the Relationship between Number of days and distance traveled :

Recall :

Speed = distance / time

Speed = 80 ; distance = d ; time = t

80 = d/t

80 * t = d

d = 80t

Answer:

-23

Step-by-step explanation:

Given 4v-3

evaluate when v = -5

So basically we want to find the value of the expression when the variable (v) equals -5

so

* plug in -5 for v*

4(-5)-3

4*-5=-20

-20-3=-23

So we can conclude that when v = -5 the value of the expression is -23

Answer:

Explanation:

given the expression: 4v-3

if  v = -5

4v-3 (let's subsitute v)

4v-3 = 4×(-5)-3

4v-3 = -20 - 3

4v-3 = -23

Answer:

5,5,7,*9,11,*12,16,23

Step-by-step explanation:

Since, the data has an even amount of numbers once, you put your numbers in order you place your pointer fingers from the 1st to last number & continue to move closer. There is an even amount of numbers so you would have to add the 2 numbers up & then divide them by 2.

9+11=20 divided by 2=10

Answer:

The first person to arrive is not random. The person that mostly arrives first every time is the person who lives closest to the school, or is a teacher's pet.

The odds of the person who lives 20km away from the school being first are way lower than anyone else.

A better method, would be everyone writes their name on a paper, and the teacher picks one at random from a hat.

Answer:

3/18

Given:

The areas of two similar squares are 16m² and 49m².

To find:

The scale factor of their side lengths.

Solution:

We know that the ratio of the areas of the similar squares is proportional to the ratio of square of there sides.

[tex]\dfrac{\text{Area of first square}}{\text{Area of second square}}=\dfrac{(\text{Side length of first square})^2}{(\text{Side length of second square})^2}[/tex]

[tex]\dfrac{16\ m^2}{49\ m^2}=\dfrac{s_1^2}{s_2^2}[/tex]

[tex]\dfrac{4^2}{7^2}=\left(\dfrac{s_1}{s_2}\right)^2[/tex]

[tex]\left(\dfrac{4}{7}\right)^2=\left(\dfrac{s_1}{s_2}\right)^2[/tex]

Taking square root on both sides, we get

[tex]\dfrac{4}{7}=\dfrac{s_1}{s_2}[/tex]

[tex]\dfrac{s_1}{s_2}=\dfrac{4}{7}[/tex]

Now, the scale factor is the ratio of side length of second square to the side length of first square.

[tex]k=\dfrac{s_2}{s_1}[/tex]

[tex]k=\dfrac{7}{4}[/tex]

Therefore, the scale factor of their side lengths is [tex]k=\dfrac{7}{4}[/tex].

Step-by-step explanation:

The given recipe makes 8 bags.

To make 16 bags, Lily needs twice as many ingredients because 8 + 8 = 16.

Since 1 cup of raisins makes 8 bags, 2 cups of raisins will make 16 bags.

To show the mathematical way:

Variable w = number of cups of raisins

1/8 = w/16

Cross multiply

1 × 16 = 8 × w

16 = 8w

2 = w

2 cups of pretzels makes 8 bags so 6 cups of preztels will make how many bags?

Set up an equation:

Variable x = number of bags

2/8 = 6/x

Cross multiply

2 × x = 8 × 6

2x = 48

x = 24

6 cups of pretzels will make 24 bags.

If 0.5 cup of pecans = 2.5 cups of crackers, then 1 cup of pecans = y cups of crackers?

Variable y = number of cups of crackers

Set up equation:

0.5/2.5 = 1/y

Cross multiply

0.5 × y = 2.5 × 1

0.5y = 2.5

y = 5

1 cup of pecans will need 5 cups of crackers

2 cups of pretzels = 8 bags, so 1 cup of preztels = z bags?

Variable z = number of bags

Set up equation:

2/8 = 1/z

Cross multiply

2 × z = 8 × 1

2z = 8

z = 4

Answer:

the missing value is 18.

Step-by-step explanation:

First i converted the percentage to a fraction which was 30% was 3/10 or 0.3 or 3 and 100% was 1 so i took those numbers with 54, 1, 3, and Solve for an unknown value x with this fractions calculator. Find the missing fraction variable in the proportion using cross multiplication to calculate the unknown variable x. Solve the proportion between 2 fractions and calculate the missing fraction variable in equal's.

For the equation

543=x1

The cross product is

54×1=3×x

Solving for x

x=54×13

and reducing

x=18

Solution by Proportion

Since the equation is an equality

If

3 ÷ 1 = 3

Then it is true that

54 ÷ x = 3

Solving for x

x = 54 ÷ 3

x = 18
