PLEASE HELP

answer is  

a.

5.2 inches

hope you get this right.

i may be incorrect but i believe that her first error was in step one when she multiplyed her equation by 1/4 when she should have divided it by 1/4

try this. the error is that sariah was combining a constant (4.5) with a variable with a coefficient, thus getting an inaccurate answer.

this is also assuming that you meant to put an equal sign before the 4.5 + x 35 x

to solve this problem, the strategy used is just to solve it yourself and find the correct answer by combining like terms.

hope this !
