Answer:
1.6 hours
Step by step explanation;
1 hour would make them only 150 miles apart, 60% of 120 and 60% of 130 added together is 150 mph, so 1.6 hours
Hope this helps :)
Answer:
68
Step-by-step explanation:
Let x=adult tickets and y=child tickets
1) 15x+11y=1889
2) x+y=147
multiply equation 1 by -1/11 on both sides to get:
-(15/11)x-y=-171.73
add new equation with equation 2 to get
-4/11x=-24.73
Isolate x to get:
x=67.99999
Round up to get 68 adult tickets
Answer:
It will last 18 days.
Step-by-step explanation:
Answer:
y = 2x - 1
Step-by-step explanation:
Consider the differences between consecutive values of y. If constant then this value is the multiplier.
1 - (- 1) = 3 - 1 = 5 - 3 = 7 - 5 = 9 - 7 = 2 ← constant difference, hence
y = 2x
Given the point (0, - 1 ) then we require to subtract - 1, that is
y = 2x - 1 ← equation relating x and y
