PLEASE WILL GIVE BRAINLIEST Sadie needed to get her computer fixed. She took it to the repair store. The technician at the store worked on the computer for 5 hours and charged her $77 for parts. The total was $302. Which equation could be used to determine xx, the cost of labor per hour?

A. x= 77−302/5
B. x= 302−5/77
C. 302=5(x+77)
D. 302=77+5x
​

​

Option D) 302= 77+5x

Step-by-step explanation:

Number of hours he worked = 5hrs

Take 'x' as cost per hour,

Then total cost of labor = 5x

Additional charge for parts = $77

Total amount she spent = $302

Equation for her spending= 5x+ 77 = 302

This can also be written as 302= 77+5x

Hope this helps.

y=−9/2x+10

step-by-step explanation:

let's solve for y.

0−9x−2y=−20

step 1: add 9x to both sides.

−9x−2y+9x=−20+9x

−2y=9x−20

step 2: divide both sides by -2.

−2y

−2

=

9x−20

−2

y=

x+10

x = -2

y = 848
