Answer:
Step-by-step explanation:
Set this up according to the Triangle Proportionality Theorem:
Cross multiply to get
and simplify to get
Get everything on one side of the equals sign and solve for x:
and
By the Zero Product Property,
x = 0 or 3x - 52 = 0 so x = 17 1/3
Answer:
11/14
Step-by-step explanation:
Change 4 and 2/3 to an improper fraction.
4 + 2/3 = 14/3
There are 14 of the 1/3 lb serving in 4 and 2/3 pounds of cheese.
F(f-1x) will be equal to x
take a simple example
f(x) = 2x
so x = f(x) / 2
f-1(x) = x/2
f(f-1x) = 2 ( x/2) = 2 * x/2 = x
