I believe its 17, this is a 90 degree angle, so 90-73=17
Step-by-step explanation:
-2x=15-7y
x=-7.5+3.5y
-3x-8y=4
-3(7.5+3.5y)-8y=4
-22.5-10.5y-8y=4
-22.5-18.5y=4
-18.5y=4+22.5
-18.5y=26.5
y=-53/35
the fraction might not be in lowest terms.
The distance between them is 75 miles
after 1 hour the train will go 125 miles
125 miles.....1 hour
75 miles..........x hour
x=75/125=75/125*60=36 minutes
d is the answer

Answer: % increase ≈ 3433%
Step-by-step explanation:
Step 1: work out the difference (increase) between the tow numbers you are comparing.
Increase = New Number - Original Number
Step 2: Divide the increase by the original number and multiply the answer by 100.
% increase = Increase ÷ Original Number x 100
Step 3: Plug in known values
Increase = 6.18
Original Number = 0.18
% increase = 6.18 ÷ 0.18 x 100
% increase = 34.333... x 100
% increase ≈ 3433%
