Question

If x is 4, a is 1/4, and y is 2, then what is 5x(56a-6y)

Answer 1

Start by substituting the x's with their given value...

1) 5x = 5*4 = 20 20(56a-6y)

2) 56a = 56*1/4 = 14 20(14-6y)

3) 6y = 6*2 = 12 20(14-12)

Now you have to solve what you are left with...

20(14-12)

20*14 = 280

20*12 = 240

280-240 = 40

Your answer is 40

Hope this helps, have a great day! :)
