If f(x) varies directly with x and f(x) = 4 when x = 12, then what is the value of f(x) when x = 60?
ANTONII [103]
ANSWER

f(60)=3\times60=180

EXPLANATION
We were given that
f(x)
varies directly as
x.

We can write this mathematically as,

f(x) \propto \: x.

This implies that,

f(x) = kx
where k is the constant of variation.

f(4)=4k

This implies that,

4k=12

k = 3

The equation becomes

f(x)=3x

When x=60

f(60)=3\times60=180

Help? 11 3/4 is the quotient of a number y and 6 1/4
LUCKY_DIMON [66]

Answer:

y divided by 6 1/4 = 11 3/4

Step-by-step explanation:

First, change the mixed numbers into improper fractions:

y divided by 25/4 = 47/4

Next, multiply both sides by 25/4:

y divided by 25/4 x 25/4 = 47/4 x 25/4

The 25/4's on the left side of the equation cancel each other out, leaving you with:

y = 47/4 x 25/4

Multiply 47 x 25 and keep the same denominator:

y = 1,175/4

Divide and:

y = 293 3/4
