Answer:
30.5 hours
Step-by-step explanation:
If he were to average 8 hours PER week for 4 weeks, his total sum would have been:
8 * 4 = 32 hours
But he fell short of it. By how much?
By 
hours!
So, he practiced 1 1/2 hours LESS THAN 32 hours, so his practice time is:
So, <u>he practiced 30.5 hours in the 4 weeks</u>
the correct answer is a^6
Answer:
(7,2)
Step-by-step explanation:
5x + 3y = 41
3x - 6y = 9
Multiply the first equation by 2
2(5x + 3y) = 41 *2
10x +6y = 82
Add this to the second equation
10x +6y = 82
3x - 6y = 9
----------------------
13x = 91
Divide by 13
13x/13 = 91/13
x=7
Now we can find y
5x+3y = 41
5(7) +3y =51
35+3y=41
Subtract 35 from each side
35-35+3y=41-35
3y = 6
Divide by 3
3y/3 = 6/3
y=2
