Answer:
Step-by-step explanation:
16.
(3/5)y = 6
Multiply both sides by 5
3y = 6 times 5
Divide both sides by 3
y = 30/3
y=10
18.
(6/7)c = 18
Multiply both sides by 7
6c = 18 times 7
Divide both sides by6
c = 21
20.
(11/12) = (3/4)h
Multiply both sides by 4
11/3 = 3h
Divide both sides by 3
h = 11/9
22.
m/26 = -1/2
Multiply both sides by 26
m = -13

-47 - 15y =-17.....Equation A
-x+ 5y=-13..........Equation B
Solve B for y.
-x + 5y = -13
5y = x - 13
y = (x - 13)/5
Plug y into A.
-47 -15y = -17
-47 -15(x - 13)/5 = -17
-47 -3(x - 13) = -17
-47 -3x + 39 = -17
-3x - 8 = -17
-3x = -17 + 8
-3x = -9
x = -9/-3
x = 3
Now that we know x is 3, plug 3 for x into EITHER Equation A or B (your choice) to find y.
I will let you do that.
in every quart, there are 4 cups.
16 * 4 = 64
16 quarts = 64 cups
Answer:37%
Step-by-step explanation:
There are 19 children, so the denominator is 19.
There were 7 playing dress-up, so the numerator is 7.
The fraction is . 7/19=0.3684~0.37
To convert decimals into percentage, mulitply by 100 and use a percent sign.
0.37*100=37%
