Let the person's arm length be = x
Condition is : sleeve lengths available from 20 inches to 40 inches and the length of the sleeves should be about 1.2 times a person's arm length.
So, the inequality equation becomes:
This gives x=
or 
or x=
=33.33 or 
Hence, the shop does not provide tuxedos to people with arm length less than 16.66 inches and greater than 33.33 inches.

The amount in the passbook account is $11,000 and the money in the money market account is $8000
Let:
a represent the unknown amount in the passbook account
b represent the unknown amount in the money market account
From the question, the following information can be gathered:
- The money in the passbook account exceeds the amount in the money market account.
This information can be represented with this equation : a - b = 3000
- The interest paid on the passbook account exceeds the interest paid on the money market account.
This information can be represented with this equation : 0.08a - 0.10b = 80
The two equations gotten above would be solved using simultaneous equation and the elimination method
a - b = 3000 equation 1
0.08a - 0.10b = 80 equation 2
Multiply equation 1 by 0.08
0.08 - 0.08b = 240 equation 3
Subtract equation 2 from 3
0.02b = 160
Divide both sides of the equation by 0.02
b = 8000
Substitute for b in equation 1
a - 8000 = 3000
Add 8000 to both sides
a = 11,000

Answer:
Step-by-step explanation:
f(x) = (2x / 7) + 4.....change f(x) to y
y = (2x / 7) + 4.......switch ur x and y and solve for y
x = 2y/7 + 4....subtract 4 from both sides
x - 4 = 2y/ 7.....multiply by 7
7(x - 4) = 2y....divide by 2
7(x - 4) / 2 = y ........answer C
