Which choice represents the equation w + 2y= 9 solved from y.

y = (w + 9) divided by 2

y= (w - 9) divided by 2

w = 2y + 9

y= (9 - w) divided by 2

Choose all the steps that solves 2w - 6n = 3x for x.

divided both sides by -3

divided both sides by 3

add 6n from both sides.

add -3 to both sides

Consider the equation P=2L+2W. To solve for W you must first....

add 2L to both sides

multiply both sides times two

subtract 2L from both sides

divide both sides by 2

1 point

Consider the equation y=mx + b To solve for m you must first....

subtract b from both sides

divide both sides by x

subtract y to both sides

multiply both sides times x

Consider the equation V=LWH solved for W is

W= V / WH

W= VLH

W= VWH

W= V / LH

1 point

Consider the equation y=mx + b. To solve for b you must first....

divide both sides by mx

multiply both sides times mx

add y to both sides

subtract mx from both sides
