What is 3.3(x-8)-x=1.2
11Alexandr11 [23.1K]
Multiply 3.3 by everything in the parenthesis.

3.3x - 26.4 - x = 1.2

Combine like terms.

2.3x - 26.4 = 1.2

Add 26.4 to both sides.

2.3x = 27.6

Divide 2.3 on both sides.

x = 12

Hope this helps!

The slope of a hill next to a highway decreases 2 vertical feet for every 3 horizontal feet away from the highway.
Novay_Z [31]

Slope is the change in Y ( vertical) over the change in X( horizontal).

The slope would be -2 /3

You would multiply the horizontal distance by the slope:

-2/3 x 12 = -8

The answer would be D. v(h)=-2/3h, and the vertical distance is -8 feet.
