Answer:Tax Rate = 7.75%
Step-by-step explanation:
The three equivalent ratios are 27/6, 45/10, and 36/8.
Given,
The ratio of right-handed students to left-handed students is 18:4.
We need to find three equivalentratios of 18:4.
A ratio is denoted by A:B.
If the ratios are equal we called it proportion.
Example:
2/4 = 16/32 = 6/12
2/4 = 1/2
16/32 = 2/4 = 1/2
6/12 = 1/2
2/4, 16/32, and 6/12 are equivalent ratios and they are in proportion.
We have,
18:4
It can be written as:
= 18/4
Reducing it to the smallest term.
= 2 x 9 / 2 x 2
= 9 / 2
So,
We can have,
27/6, 45/10, and 36/8 as our equivalentratios.
27/6 = 3 x 9 / 3 x 2 = 9/2
45/10 = 5 x 9 / 5 x 2 = 9/2
36/8 = 4 x 9 / 4 x 2 = 9/2
Thus the three equivalent ratios are 27/6, 45/10, and 36/8.

To find the inverse, interchange the variables
so the Answer is 4 - 1 (x) = - 5 + 2x well thats your answer Hope this helps :)
Step 1:Replace f (x) with y
so y = x + 5 and the denominator 2
Step 2:Interchange the Variables x = y + 5 but the denominator stays the same
Now solve for y
since y is on the right of the equation switch sides so its on the left side
Step 3:y + 5 and the denominator 2 equals x
Step 4: Still solve for y Which is y = - 5 + 2x
Step 5: Solve for y and replace with 4 - 1 (x) to show the final Answer
Now the Answer is 4 - 1 (x) = - 5 + 2x
