8x - 2y = 48, y =4
8x - 2(4) = 48
8x - 8 = 48
8x = 48+8
8x = 56
x = 56/8 = 7
x = 7
Answer:
12.5
Step-by-step explanation:
f of x just means y, so you're just finding y when x = 1/2
1 quart is equal to 4 cups so the answer is B.
K=d
d=5
Since K is equal to d, and d is 5, the value of K is 5.
K=5
5(K)=5(d)
Fourth one since x is 2 and the y is 1
