This problem can solve by the rule of three.
42 installations-----------------------6 hours
147 installations---------------------- x
x=(147 installations * 6 hour) / 42 installations=21 hours.
Answer: 21 hours.
The answer is C bruh
9.9x9.9=98.01
98.01/2=49.005
Area of triangle= length x base / 2
Answer: 2, 4, 6, 8
Step-by-step explanation:
Just plug x into the equation for each one.
x = -3

With this one, you can see it is a linear equation and for every increase of 3 on x, y in increased by 2.
x -6 -3 0 3 6
y 0 2 4 6 8
<span>Quin is adding the compensation needed instead of subtracting. First she calculated 40x4. She is trying to find 37x4. To do this, she would have to instead gather all the data:
3x4 = 12
40x4 = 160
Subtract instead of add:
40x4 - 3x4 = ?
160 - 12 = 148
The answer is 148.</span>

The domain is all real numbers as a composition of two linear functions have no restrictions (all linear functions have domain of R)
