<h3><u>The value of the first number, x, is equal to 18.</u></h3><h3><u>The value of the second number, y, is equal to 90.</u></h3><h3><u>The value of the third number, z, is equal to 77.</u></h3>
x + y + z = 185
y = 5x
z = y - 13
Because we already have a value for y, we already have a value for z. We can now solve for a value of x.
x + 5x + 5x - 13 = 185
Add 13 to both sides.
x + 5x + 5x = 198
Combine like terms.
11x = 198
Divide both sides by 11.
x = 18
Because we have a value of x, we can solve for the exact values of y and z.
y = 5(18)
y = 90
z = (90) - 13
z = 77
Answer:
0.21875
Step-by-step explanation:
We can find the percent of a number by multiplying the number by 0.25 after converting the number from a fraction to a decimal.
7/8=0.875
0.875(0.25)=0.21875

1 cup = 8 ounces
3/4 cup = 8*(3/4)
3/4 cup = 6 ounces
She will add 6 ounces of water as it is equivlent to a 3/4 cup
