Step-by-step explanation:
Miles = 15 1/10
Miles = 151/10 miles
Hour = 1/3 hour
Av = 151/10 miles / 1/3 hour
Av = 151/10 × 3 / 1/3 × 3
Av = 453/10 miles / hour
Av = 45,3 mil / h
The answer to this question is y' = 10x^2 + 6. You have to use the power rule to bring the exponent down as a coefficient and then reduce the exponent by 1. Do it for all the terms using the sum rule for derivatives (derivative of a sum of the sum of its derivatives).

Step-by-step explanation:
I understand you hardships your going through. I believe you feel like you've lost your best friend, and I have gone through a similar experience when I was in 7th grade.

This made me motivated to see how much time was left for my to see him coming back! I hope this helps.
Answer:
Equation = 1/4 x + 25 = 70
Solution = $180
Explanation:
Let the original amount she had before she went shopping be x
If she spent one-fourth on sloth, then the amount spent on cloth will be;
1/4 x
If she receives another $25 a week later totalling her money $70, then the equation that represents the situation will be;
1/4 x + 25 = 70
Find the solution
1/4 x + 25 = 70
1/4 x = 70 - 25
1/4 x = 45
x = 45 * 4
x = 180
Hence the amount she had before going for shoppind was $180
