when you find x-intercept, you are finding the coordinate when y=0, hence sub y=0,
-8x-16=0
8x=-16
x=-2
Answer:
x = 109
Step-by-step explanation:
75 + 45 + y = 180
120 + y = 180
y = 60
60 + 79 + z = 180
z + 139 = 180
z = 41
41 + 68 + a = 180
109 + a = 180
a = 71
x + a = 180
x + 71 = 180
x = 109
Answer:
13 seconds
Step-by-step explanation:
I just found out what 67%+3=3.67 and then that gives you 6.67 gallons or if you round up 7 gallons and then I added that to the 9 second rate which would give you 12.67 or rounding up 13 seconds.

=16.7332
That is one side of the square, so multiply by 4
=66.93
