Solve for b. 5b + 8 - 2b = 7b. A 2 B.4/5 C.4/7 D.1/2​

b=2

Step-by-step explanation:

5b + 8 - 2b = 7b

Combine like terms

3b+8 = 7b

Subtract 3b from each side

3b+8-3b = 7b-3b

8 = 4b

Divide each side by 4

8/4 = 4b/4

2 =b

b=2

Step-by-step explanation:

Simplifying

5b + 8 + -2b = 7b

Reorder the terms:

8 + 5b + -2b = 7b

Combine like terms: 5b + -2b = 3b

8 + 3b = 7b

Solving

8 + 3b = 7b

Solving for variable 'b'.

Move all terms containing b to the left, all other terms to the right.

Add '-7b' to each side of the equation.

8 + 3b + -7b = 7b + -7b

Combine like terms: 3b + -7b = -4b

8 + -4b = 7b + -7b

Combine like terms: 7b + -7b = 0

8 + -4b = 0

Add '-8' to each side of the equation.

8 + -8 + -4b = 0 + -8

Combine like terms: 8 + -8 = 0

0 + -4b = 0 + -8

-4b = 0 + -8

Combine like terms: 0 + -8 = -8

-4b = -8

Divide each side by '-4'.

b = 2

Simplifying

b = 2

the reason why your question keeps getting deleted because this is not a school related question : )

i will answer your question though.

i never tried church's

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .
