Answer:
First question --> C) 8.5h
Second question --> D) 2
Step-by-step explanation:
First question
Terry earns $10 per hour
Jill earns 20% less which is $2 less
Jill earns $8 per hour
Jerry earns $0.50 more per hour than Jill
Jerry earns $8.50 per hour
Second question
x = 2
y = 4
(2x + 3y) / 4 - 2 = ?
Use PEMDAS
so Parentheses first, then divide, then subtract
So.... (2x + 3y) = (2*2 + 3*4) = (4 + 12) = 16
Then divide
16/4 = 4
Then subtract
4 - 2 = 2
Answer:
1. a. His new texting speed after one month is 2 + 1/2 = 2.5 characters per second.
b. After two months it will be 2 + (1/2) * 2 = 3 characters / second.
c. Answer is 2 + 1/2 * 3 = 3.5 characters/second/.
2. The answer is s = 1/2m + 2
3. To solve for m we write 8 = 1/2m + 2 → 6 = 1/2m → m = 12 months.
4. 10r + 4 = 8 → 10r = 4 → r = 0.4
5. The variable r represents the rate she must increase her texting speed by per month.
6. A scenario could be "Allison has 37 marbles in a jar. She took out 5 from the jar and wants to divide the remaining amount equally among her 8 friends. How many marbles does each friend get?".
Answer:
13.8 square feet
Step-by-step explanation:
To find the area of a triangle you use the formula a = 1/2 bh
a = 1/2 (6.9) (4) = 13.8
(simplier to understand) a = 1/2 (6.9) (4) = 27.6 divided by 1/2 = 13.8
Divide 754 by 13 and you get 58
Now multiply by 9 and you get 522 miles.
Answer:
8:19
Step-by-step explanation:
