Answer:

(-1, -2)

Step-by-step explanation:

multiply the top equation by 5

multiply the bottom equation by 3

15x - 25y = 35

15x - 6y = -3

subtract these two - x values cancel

-25 y = 35

6 y  = 3

-19y = 38

y = -2

plug this back in to get x

15x + 12 = -3

15x = -15

x = -1

7th grade math please help me will give brainliest
Alecsey [184]

Answer: 67.27

Step-by-step explanation:

7.1 x 7.1 for the square = 50.41

7.1 divided by 2 = 3.55

3.55 x 4.75= 16.86

Normally here you would divide by 2, but you don’t need two because there is 2 triangles that are the same

Add the 50.41 and the 16.86 and you have your answer!

7x- 3(x- 6) = 30<br> A. X=3<br> B.x=9<br> C.x=6<br> D.x=12
Rufina [12.5K]

Answer:

x=3

Step-by-step explanation:

1. Simplify the expression

7x-\left(3\cdot\left(x-6\right)\right)=30

Solve by distributing:

7x-\left(3x+3\cdot-6\right)=30

Simplify the arithmetic:

7x-\left(3x-18\right)=30

Expand the parentheses:

7x-3x+18=30

Simplify the arithmetic:

4x+18=30
