Answer:
thats what she said
Step-by-step explanation:
The two friends will be 150 miles apart, when the sum of the distances covered by the them is 150 miles.
distance = speed x time.
Let the time covered when they are 150 miles apart be x, then:
40x + 35x = 150
75x = 150
x = 150/75 = 2.
Therefore, the two friends will be 150 miles apart in 2 hours.
77/5=99/x
77x=5*99
77x=495
x=495/77
x=6.4
she needs to study 6.4 hrs to get 99
I didn't understood the question in my view the question must be (6x + 4) = 82
Answer:
x = 13
Step-by-step explanation:
6x = 82 - 4
6x = 78
x = 78/6
therefore; x = 13
