1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

-80x+28y-56 is the correct answer

Which expressions are equivalent to 8(-10x+3.5y-7)
 -1

Explanation:

First we need to find the slope of this given line.

The two points on here are (0,-3) and (3,0)

Apply the slope formula

m = (y2-y1)/(x2 - x1)

m = (0-(-3))/(3-0)

m = (0+3)/(3-0)

m = 3/3

m = 1

The slope of the given line is 1. The negative reciprocal of this is -1, which is the perpendicular slope.

Side Note: Any two perpendicular lines always have their slope multiply to -1, as long as neither line is vertical.
