1. H+S=40
2. 19H+25S=922
From 1,
19H+19S=760
Subtract this from 2 to eliminate H,
19H+25S-19H-19S=922-760
6S=162
Solve for S, then use either equation to solve for H.
Answer:

Explanation:
To find the inverse of a function expressed as
XXX
y
=
an expression in
x
rearrange the expression into the form:
XXX
x
=
an expression in
y
Given
XXX
y
=
3
x
2
−
5
Switch sides and add
5
to both sides
XXX
3
x
2
=
y
+
5
Divide both sides by
3
XXX
x
2
=
y
+
5
3
Take the square root of both sides
XXX
x
=
±
√
y
+

Since we were asked for an inverse function, I've eliminated the non-primary root (a function can not have two values for a single argument value).
Therefore
XXX
x
=
instead of Y do G
Step-by-step explanation:
The maximum number of microwave ovens the two employees can take on the elevator is 7.
<h3>How to find the maximum number of microwave ovens the two employees can take on the elevator?</h3>
To solve the question, we have to find the simple equation showing the relationship between all the weights an the maximum weight the elevator can carry
Let
- x = number of microwave ovens
Since the micro wave weighs 45 pounds, the total weight of microwave ovens is W = 45x.
Also, there are 20 televisions on the elevator. If each television weighs 85 pounds, the total weight of televisions is W' = 20 × 85 = 1700 pounds
Also, the weight of the equipment and the two employees is W" = 400 pounds.
Since the maximum weight on the elevator is 2400 pounds, we have that the required simple equation is
W + W' + W" = 2400
45x + 1700 + 400 = 2400
45x + 2100 = 2400
45x = 2400 - 2100
45x = 300
x = 300/45
x = 6.67
x ≅ 7
So, the maximum number of microwave ovens the two employees can take on the elevator is 7.
