Rashid reads a total of 35 pages every 5 days. Based on this information, how many days will it take Rashid to read a total of 84 pages.

12 days

Step-by-step explanation:

35 pages in 5 days

7 pages in 1 day

84 / 7 = 12

if x decreases by 4 then y increases by 10

step-by-step explanation:

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
