'12' and '48' (choices 'A' and 'D') will both work as common denominators.
The least one is '12' .
Since 4 is a factor of 12, any multiple of 12 is also a multiple of 4 , and can
serve as a common denominator. The smallest multiple of 12 is 12 itself.
This is a fraction equal to
2 1 ÷ 4 8
We want a unit rate where
1 is in the denominator,
so we divide top and bottom by 4
2 1 ÷ 4
4 8 ÷ 4
=
0.5 1
1 8
=
0.5 1
8
= 0.5 1 per 8
DIVIDE THE 920 BY 7.50 AND YOU SHOULD GET YOUR ANSWER
Answer:
f(x)⁻¹ = 3x - 18
Step-by-step explanation:
I'm going to assume that 1/3 is the coefficient of the x.
f(x) = 1/3x + 6
y = 1/3x + 6
x = 1/3y + 6
x - 6 = 1/3y
3x - 18 = y
f(x)⁻¹ = 3x - 18
