60% of what number is equal to 307

511.6

Step-by-step explanation:

Reverse the order in which you define 60%

x / .6 (or 60%) = 307

Reverse it to get;

307 = .6(x)

Solve for x;

307 / .6 = x / .6

511.6 = x

TA-DA! I hope this helped ^<^

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
