Answer:
x = -2 and y = 0
Step-by-step explanation:
5x + y = -10
4x - 7y = -8
Rearrange the first equation to equal y.
5x + y = -10
y = -10 - 5x
Replace y in the second equation with the first equation.
4x - 7y = -8
4x - 7(-10 - 5x) = -8
4x - (-70 -35x) = -8
4x + 70 + 35x = -8
Rearrange the equation to find x.
4x + 35x = -8 - 70
39x = -78
x = -2
Now that you know x, use the rearranged first equation to find y.
y = -10 - 5x
y = -10 - 5(-2)
y = -10 + 10
y = 0
Answer:
70
Step-by-step explanation:
9/100=0.09
9-2.7=6.3
6.3/0.09=70
Answer:

Step-by-step explanation:
Given: Travis and Tony took 40 minutes to skate 5 miles and the return trip took them 30 minutes
To find: average speed for the trip
Solution:
Total distance = 5 + 5 = 10 miles
Total time = 40 + 30 = 70 minutes
So,
Average speed for the trip = Total distance/Total time =
miles/minute
