You were on the right track.
(17/4)*(11/4)*(3/1)
first multiply the numerators
17*11*3 = 561
561 / ?
next multiply the denominators
4*4*1 = 16
561 / 16 = 35.0625 = 35 1/16
Note as a fact:
H⁻¹(H(x)) = x
Option C.
Answer:

Step-by-step explanation:

We will set each parentheses equal to 0
x - 4 = 0
x = 4
-5x + 1 = 0
x = 1/5
The lesser value will be 1/5
The greater value will be 4
Step-by-step explanation:
If x is the mass of 30% copper alloy, and y is the mass of 65% copper alloy, then:
x + y = 80
0.30x + 0.65y = 0.51(80)
Solving the system of equations using substitution:
0.30x + 0.65(80 − x) = 0.51(80)
0.30x + 52 − 0.65x = 40.8
11.2 = 0.35x
x = 32
y = 80 − x
y = 48
The metalworker needs 32 kg of 30% copper alloy and 48 kg of 65% copper alloy.
