Answer:
C. $97
Step-by-step explanation:
The average of his wage for all 15 days is the sum of all wages for the 15 days divided by 15.
average wage for 15 days = (sum of wages for the 15 days)/15
The amount of wages during a number of days is the product of the average wage of those days and the number of days.
First 7 days:
average wage: $87
number of days: 7
total wages in first 7 days = 7 * $87/day = $609
Last 7 days:
average wage: $92
number of days: 7
total wages in last 7 days = 7 * $92/day = $644
8th day:
wages of the 8th day is unknown, so we let x = wages of the 8th day
total wages of 15 days = (wages of first 7 days) + (wages of 8th day) + (wages of last 7 days)
total wages of 15 days = 609 + x + 644 = x + 1253
average wage for 15 days = (sum of wages for the 15 days)/15
average wage for 15 days = (x + 1253)/15
We are told the average for the 15 days is $90/day.
(x + 1253)/15 = 90
Multiply both sides by 15.
x + 1253 = 1350
Subtract 1253 from both sides.
x = 97

Answer:

Step-by-step explanation:
2 + m
Rewrite with variable first.
m + 2
m + 2
Can’t be simplified further.
m - (-2)
Distribute negative sign.
m + 2
-2-m
Rewrite with variable first.
-m - 2
The last expression is not equivalent to m+2.
Answer:
This equation is incorrect. The equation simplifies to -3=4 which is incorrect.
Step-by-step explanation:
3(-3)=-9. 3(2)=6
-9+6=-3
-3=4 FALSE
Here are the answers.
6. 63/100
7. 75/100 = 3/4
8. 91/100
9. 18/100 = 9/50
10. 3/100
11. 25/100 = 1/4
12. 5/100 = 1/20
13. 16/100 = 4/25
14. 1/100
15. 79/100
16. 40/100 or 4/10 = 2/5
17. 99/100
18. 30/100 or 3/10 = 3/10
19. 15/100 = 3/20
20. 84/100 = 21/25
