1. Rewrite the equation 5(x - 3) = x + 13 with 6 substituted for x. Write a
question mark over the equal sign to show that you're testing to see if the
equation is true

2. Simplify both sides. Show your work.

3. Is x = 6 a solution to the equation? Why or why not?

4. Find a value of x that is a solution to 5(x - 3) = x + 13. Describe how you
found the solution

Answers

Answer 1

Answer:

Step-by-step explanation:

5(6-3)=6+13 -simplify

30-15=6+13

15=19

x doesnt equal 6

5(x-3)=x+13

5x-15=x+13

4x=28

x=7

4x=28

4(7)=28

28=28

Fred's age is 82.

Amanda's age is 27.

Catherine's age is 14.

Blake's age is 12.

The equation that represents Fred's age is: 1 + 3x =

Where x is Amanda's age

Fred and Amanda's age : 109 = 1 + 3x + x

4x + 1 = 109

4x = 109 - 1

4x = 108

x = 108 / 4

x = 27

Fred's age = 1 + (3 x 27) = 82

The equation that represents Blake's age is: b = 2c - 16

Where: b = Blake's age

c = Catherine's age = 2 + b

b = 2(2 + b) - 16

b = 4 + 2b - 16

16 - 4 = 2b - b

12 = b

Catherine's age = 12 + 2 = 14

What is the distance between (2. 6) and (7, 6)

Answers

Answer:

Step-by-step explanation:

Hey There!

So first off the y values are the same so to find the distance between the two points all we have to do is subtract the largest x value from the smallest x value

7-2=5

Therefore the distance between the two points is 5

Answer: 5

Step-by-step explanation:

D = √(x₂ - x₁)² + (y₂ - y₁)²

x₁ =2 y₁ =6 x₂ =7 y₂ =6

D =√(7-2)² +(6-6)²

D=√(5)² +(0)²

D =√25

Answers

22.5 miles in 2 hours.....

First find out how many times 8 minutes fits into two hours. Since one hour is 60 minutes, 2 would be 120. Perform 120/8 and get 15. This means that 8 minutes fits 15 times into 2 hours. Then, you’re going to multiply 1.5 x 15 and get the answer, 22.5. The person can tune 22.5 miles in 2 hours

Find the area and the circumference of a circle with radius 2yd. Use the value 3.14 for pie and do not round your answer. Be sure to include the correct units in your answer

Answers

Answer:

circumference: 12.56 yd

area: 3.14(2 yd)² = 12.56 yd²

Step-by-step explanation:

The circumference formula is C = 2πr (pi, not pie), where r is the radius.

When r = 2 yd and π ≈ 3.14, the circumference is:

C = 2(3.14)(2 yd) = 12.56 yd

Step-by-step explanation:

Answer: 4) 8.95h + 10 < 115

Step-by-step explanation:

We know the inequality will be equal to less than 115 since it states that the order was less than $115.

The equation would look like: some amount of shin guards times 8.95 each + $10 shipping = less than $115

8.95h + 10 < 115
