16 because it’s basic multiplication
Answer:
20 hours
Step-by-step explanation:
use this linear equation
y = 9.25x + 50
plug in 235 for y and solve for x
235 = 9.25x + 50
185 = 9.25x
20 = x
so he worked for 20 hours

Answer:
RQS=110
TQS=70
Step-by-step explanation:
(12x+2)+(7x+7)=180
The two equations added together give us a straight line which is angle 180
19x + 9 = 180
19x = 171
We solve for x
x = 9
Now that we have x we plus in to each equation
RQS= (12(9)+2)
= 110
TQS=(7(9)+7)
=70
