1/2m−5=23. What is the answer please tell me, it's very important.
olga_2 [115]

Answer:

m = 56

Step-by-step explanation:

1/2m - 5 = 23

add 5 to both sides

1/2m - 5 + 5 = 23 + 5

1/2m = 28

multiply both sides by 2

1/2m(2) = 28(2)

m = 56

How does finding the square root of a number compare to finding the cube root of a number? Use the number 64 in your explanation
lakkis [162]
In order to find the square root, we must find a number that when multiplied by itself one time, it produces the number under consideration.
In the case of 64, the square root is 8 because 8 multiplied once by itself is 64.

However, when finding the cube root, the root must multiply by itself two times and make the number. 
In the case of 64, 4 multiplied by itself two times is 64.
