Answer:
yeah
Step-by-step explanation:
The power to a power rule is : KEEP THE BASE AND MULTIPLY THE POWERS.
Ex. (x^3)^4 = x^(3*4) = x^12
So ....
(7^10)^5 = 7^50
Last option is correct.
Step-by-step explanation:
3 hours =5 pages
8 hours =x
Cross multiplying
3x=5×8
3x=40
Dividing both sides by 3
3x/3=40/3
x=13.33
To the nearest whole number Henry will write 13 pages in 8 hours
Hey there!☺



Start by simplifying 28/7:

Now multiply 4 by what we have left, which is 4:

16 is your answer.
Hope this helps!☺
Constant of proportionality is given by: y=kx oy 
So lets suppose y = 50 and x = 5 so k will be 
This 10 will remain constant. For every $50 Michael saves $5, for $100 he will save $10 , for $150 he will save $15 and so on.
So this 'k' will be same for each value of x and y.
