Answer:
x = -3
Step-by-step explanation:
First Subtract the lowest variable which would be "y" from 9y. 9y changes to 8y and y cancels out, bring everything else down. the equation is now 8y-1=-25. Now add positive one to both sides -25 becomes -24 and -1 cancels out. the equation is now 8y=-24. -24 divided by 8 equals -3 and the 8y cancels out. the equation is now x equals -3.
C. The square root of 144

Answer:
1.98 miles per hour.
Step-by-step explanation:
Let x miles per hour be the average rate on the return trip,
∵ The speed on round trip is 5 miles per hour faster than on return trip,
So, the speed in round trip = (x+5) miles per hour,
Now, distance in one sided trip = 6 miles,
Since,
According to the question,
Time taken in return trip - Time taken in round trip = hours,
By quadratic formula,
∵ speed can not be negative,
Hence, average rate on the return trip would be 1.98 miles per hour.
