Answer:
Step-by-step explanation:Total hours:2 hours
Total distance:120 miles
speed: 120miles/2hours equal to 60miles/hour
Follow the method of rise over run and a is your answer
The sides of the triangle are 3x, 4x and 5x
3x + 4x + 5x = 90
12x = 90
x = 90/12
x = 7.5
first side = 3x = 3 * 7.5 = 22.5 cm
second side = 4x = 4 * 7.5 = 30 cm
third side = 5x = 5*7.5 = 37.5 cm
The answer Is 2/12 because if u multiply 1 x2 it is 2 then 3 x4 which is 12
I think your answer is y=-4/7x+5
