Answer:
5
Step-by-step explanation:
15/3 - 4/3 = 11/3
15/3 = 5
To solve this problem, you need to use the Exterior Angle (Out) equation which for this problem would be
. After correctly solving the problem with this equation, you will figure out that the answer is 79.
mHJ= 79°
Hope this helped :)
Answer:
Step-by-step explanation:
x = cheaper compact disc
y = more expensive compact disc
x + y = 375.....x = 375 - y
12.95x + 14.95y = 5306.25
12.95(375 - y) + 14.95y = 5306.25
4856.25 - 12.95y + 14.95y = 5306.25
4856.25 + 2y = 5306.25
2y = 5306.25 - 4856.25
2y = 450
y = 450/2
y = 225 <==== there were 225 of the more expensive compact discs sold
x + y = 375
x + 225 = 375
x = 375 - 225
x = 150 <==== there were 150 of the cheaper compact discs sold
check...
12.95x + 14.95y = 5306.25
12.95(150) + 14.95(225) = 5306.25
1942.50 + 3363.75 = 5306.25
5306.25 = 5306.25 (correct)
2w + 2L = 100
2w = L - 8
L - 8 + 2L = 100
3L = 108
L = 36
2w = L - 8
2w = 36 - 8
2w = 28
w = 14
Length is 36, Width is 14
