2. 43.75 (.35*125)
3. 156.4 (.46*340)
4. 117 (.65*180)
5. 54 (.75*72)
6. 550 (99/.18)
7. 375 (345/.92)
8. 260 (143/.55)
9. 300 (141/.47)
Step-by-step explanation:
First 4:
multiply percent by total
alternate: convert % to decimal by /100, then multiply by total
Last 4:
ex. X * 18% = 99, so divide by 18% (or .18)
Answer:
18÷25 =0.72 convert proper fraction to decimal ,divide the numerator by the denominator.
3-0.72=3.72. add this decimal number to the whole number .final answer is 3.72

Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
f(x) = x + 3
g(x) = -x + 2
(f + g)(x) is f(x) + g(x)
<u>Step 2: Find</u>
- Substitute in function values: (f + g)(x) = x + 3 - x + 2
- [Subtraction] Combine like terms (x): (f + g)(x) = 3 + 2
- Add: (f + g)(x) = 5
