60% of what number is 36 as an equation

Step-by-step explanation: To answer the question 60% of what number is 36, one way to solve would be to translate the question into an equation.

First we have 60% which we need to write as a decimal and remember to write 60% as a decimal, we move the decimal point 2 places to the left and we get .60 or just .6 so 60% translates to the decimal .6.

Next we have "of what number" that's times x

and "is 36" means equals 36.

So our equation is (.6)(x) = 36.

-13

step-by-step explanation:

f(-4)   means let x=-4

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

f(-4) =-8-5
