Answer:
By 3.
Step-by-step explanation:
-12-3=-15
Hope this helps!
-12 exceeds -15 by 3
To find out by how much a exceeds b, subtract a - b.
For example, by how much does 8 exceed 6?
Here, a = 8 and b = 6.
a - b = 8 - 6 = 2
2 is correct since we know that 8 is 2 greater than 6.
Now we do this problem.
By how much does -12 exceed -15?
a = -12; b = -15
a - b = -12 - (-15) = -12 + 15 = 3
Answer: -12 exceeds -15 by 3
if angle 2 is 117 degrees, angle 3 is supplemental and would be 63 degrees.
180-117=63

Dominos is the better deal.
the answer is 4
if y=21 the we substitute in the main equation
21=8x-11
8x=32
x=4
