Answer:
total - given, 360 -139 = 221
The answer would be 93% because first we need to do the reverse of how to find the mean... 80 * 4 = 320 and so we just have to subtract the grades from 320... 320 - 79 - 66 - 82 = 93... Thus Jordan's grade was 93
Answer: $34.50
Step-by-step explanation
If you multiply .75=3/4 x 10 it will will be 7.50 so 10x 3.45= 34.50 or 7.50 x 3.45= 25.875
25.875/.75 = $34.50
Answer:
697109 pennies
Step-by-step explanation:
First, you use the formula A = P (1 + rt).
R= rate which is 5.3%
T= time which is 7 years.
P is the principle which is 18790
A= is the answer
so first you multiply 7*5.3% which you get 0.371
then you multiply that with 18790 which then you get 6971.09
if you want pennies you multiply it with 100 to get 697109
6x + 5 = 4x + 5
2x + 5 = 5
2x = 0, x = 0
Y = 6(0) + 5, y = 5
Solution: x = 0, y = 5
