What is seven plus the product of six and a number, all divided by negaive five, is equal to nine, in a math problem?

Step-by-step explanation:

7 plus the product of 6 and a number, all divided by -5, = 9

the product is the result of multiplication

let the number be n

((7 + (6 * n)) / -5) = 9multiply both sides by -5 to get rid of the fraction, cancelling out the -5 on the left side

(7 + 6n) = 9 * -5

7 + 6n = -45

6n = -45 - 7

6n = -52

n = -52/6 which reduces to - 26/3

256π units²   (answer b)

step-by-step explanation:

the formula for the surface area of a sphere of radius r

is             a = 4πr²

and so, if r = 8 units, then the surface area is:

a = 4π(8 units)² = 256π units²   (answer b)
