Mr. scruggs got some money for his birthday he spent 1/5 of it on dog treats he divided the remainder among his three favorite charities if you donated $60 each charity how much money did he receive for his birthday?

$225

Step-by-step explanation:

Let x be the amount of birthday money.

$60 went to each of 3 charities totaling $180

x - 1/5x= 180

5/5x-1/5x = 180

4/5x = 180

x = 180·5/4= 225

x = 25/2304

step-by-step explanation:

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13
