It helps you because it's the same fact family
Speed = distance / time = 438 / 5 = 87.6 miles per hour
time = distance / speed = 72 / 87.6 = 0.8219 hours = (0.8219 x 60) minutes ≈ 49 minutes.
Answer:
5
Step-by-step explanation:
For the point to be a solution to the equation, it has to lie on the line 5x -2y= 30 and therefore must satisfy the equation.
5x -2y= 30
When x=8,
5(8) -2y= 30
40 -2y= 30
40 -30= 2y (bring constant to 1 side)
2y= 10 (simplify)
y= 10 ÷2
y=5
Thus the missing value is 5.
