The system of inequalities that represents the given situation are x + y ≤ 20 and 15x + 10y ≥ 90.
The parameters needed to model the inequalities;
- amount made by Opal working for a photographer = $15 per hour
- amount made in the soccer team = $10 per hour
- minimum amount Opal needs to make a week = $90
- maximum number of hours Opal needs to work = 20 hours
Let the number of hours Opal works for a photographer = x
Let the number of hours Opal works in soccer team = y
The first system of inequality in the given situation is represented as;
x + y ≤ 20
The second system of inequality in the given situation is represented as;
15x + 10y ≥ 90
Thus, the system of inequalities that represents the given situation are x + y ≤ 20 and 15x + 10y ≥ 90.

Answer:
r=20
Step-by-step explanation:
take the number you have, divide it by the numerator, and multiply it by the denominator, like shown:
4/5 of a number (r) is 16
16/4=4
4*5=20
r=20

The area of the given figure is 30 square units
<h3>Area of a trapezoid</h3>
Let the given image be a trapezium
The formula for calculating the area of a trapezium is expressed as;
A = 0.5(a+b)h
Let
a = 17
b = 3
h = 3
Substitute into the formu;a
A = 0.5(3+17)*3
A = 10(3)
A = 30 square units
Hence the area of the given figure is 30 square units
