Answer:
I think it would be D not sure tho hope this is helpful
There are 360 degrees. So add the 2 angles you have: 95+45=140. Subtract that from the number of degrees: 360-140=220. X=220 :)
I believe it would be A because it says that the mean time is 6.7 and the standard time is 2.2
Answer:
x=8, y=4
Step-by-step explanation:
7x + 10y = 96
5(5x - 2y = 32)
7x + 10y = 96
25x - 10y = 160
32x = 256
x = 8
7(8) + 10y = 96
56 + 10y = 96
10y = 40
y = 4
