Step-by-step explanation:
<u>Step 1: Define</u>
-3|5 - s³| + 3t
s = 2
t = 1.5
<u>Step 2: Evaluate</u>
- Substitute in variables: -3|5 - 2³| + 3(1.5)
- |Absolute Value| Exponents: -3|5 - 8| + 3(1.5)
- |Absolute Value| Subtract: -3|-3| + 3(1.5)
- Absolute Value: -3(3) + 3(1.5)
- Multiply: -9 + 4.5
- Add: -4.5
Answer:
C = 15
Step-by-step explanation:
Let A = # of adults and C = # of children.
A + C = 20
15A + 10C = 225
There are several ways to solve this system; here is one of them.
From the first equation: C = 20 - A
Substitute into the second equation: 15A + 10(20 - A) = 225
Multiply, collect terms, and subtract 200 from each side: 5A = 25 => A = 5
Since C = 20 - A, C = 15
