Question

I just need 6, 7, 8, 9, and 10. Please help me if you know how to do this..

Answer 1

Explanation:

#6

a n

---- = ---- Solve for a. Note that if we multiply both sides of this equation by

m p n

m, we get a = m * ----

p

m*n

and this simplifies to a = mn/p or a = ---------

#7 Solve mx = np for x. We want to isolate x on the left side. Dividing

both sides by m isolates x on the left and adds the divisor m on the right:

np

mx = np => x = ------

m

#8 Solve c - x = d + r for x We want -x alone on the left side. Accomplish this by subtracting c from both sides, obtaining:

-x = d + r - c. Now multiply both sides by -1, obtaining x = -d - r + c
