Answer:

c = 5

Step-by-step explanation:

c/6 - 4/9 = 7/18

Make denominators equal.

3c/18 - 8/18 = 7/18

Cancel denominators since they are equal.

3c - 8 = 7

Add 8 to both sides.

3c = 7 + 8

3c = 15

Divide 3 into both sides.

c = 15/3

c = 5

I need help solving it
Oxana [17]
7. the last one

I = P R T

I = 15.75 P = 500 R = unknown T = 6

15.75 = 500 (r) (6)

divide the T and I

15.75 ÷ 6 = 500 (r) (6) ÷6

2.62 = 500 (r) *get rid of the six*

divide the P with new answer

2.62 ÷ 500 = 500 ÷ 500 *get rid of 500*

0.00524 = r

move decimal to make it in to a percentage

5.24% = R
