Answer:
w=40
Step-by-step explanation:
Let's solve your equation step-by-step.
w−8=32
Step 1: Add 8 to both sides.
w−8+8=32+8
w=40
Answer:
See below
Step-by-step explanation:
I took a19=-58 divide it by 19 both side i get a = -58÷19 (note; you can never have a neg. # on the top bring the neg. down to the bottom and divide) now its 58÷-19= -3.05 or -3 (1÷19) so a = -3(1/19) do the same to the other now. answer is a=-7 (17/21)

Answer:
Perpendicular: -2/5
Parallel: 5/2
Step-by-step explanation:
The slope-intercept formula is y=mx+b, where mx is the slope.
So in the equation y = 5/2x, 5/2 is understood as the slope.
To find a perpendicular slope you have to do the opposite (sign), reciprocal (flip denominator and numerator) of the original number.
Therefore 5/2 become negative, and then the numerator and denominator switch sides. (-2/5)
Parallel slope is the exact same as the original one so nothing changes. (5/2)
