The quantity q varies inversely with the square of m and directly with the product of r and x. When m is 4 and the product of r and x is 8, q is 2.5. What is the constant of variation? Five-eighths
Five-fourths
5
10

step-by-step explanation:

no of data

divide by no of mode

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150

definitely a. the others have almost all data points on one side of the line.
