Answer:
y = (C -0.99n)/48
Step-by-step explanation:
Undo what is done to y, in the reverse order. We have y multiplied by 48 then added to 0.99n. So, we must add the opposite of 0.99n and multiply that result by the reciprocal of 48.
C = 48y + 0.99n . . . . . . given
C - 0.99n = 48y . . . . . . add -0.99n
(C -0.99n)/48 = y . . . . . multiply by 1/48
Answer:
So first you have to do 12-2 since it's in parenthesis. It is 10. 5+4 is 9, and 9 times 10 is 90. 3 squared is 9, then you divide 90 by 9. The answer is 10.
108 = .36x
divide both sides by .36
300 = x
