Answer:

PART A

4(x+5)=9x+4x-34

4(x+5)=9x+4x-344x+20=13x-34

4(x+5)=9x+4x-344x+20=13x-344x-13x=-20-34

4(x+5)=9x+4x-344x+20=13x-344x-13x=-20-34-9x=-54

4(x+5)=9x+4x-344x+20=13x-344x-13x=-20-34-9x=-54-9. =-9

4(x+5)=9x+4x-344x+20=13x-344x-13x=-20-34-9x=-54-9. =-9=6

If x varies directly as y, and X = 24 when y= 21, Find x when Y=6

Ne4ueva [31]

Answer:

x = 48/7

Step-by-step explanation:

There's two good ways to do this problem.

Option 1:

Translate "x varies directly as y" into the equation y=kx

Then you have to find k. After you "reset" your y=kx equation, fill in k and then solve for x. See image.

Option 2:

Translate "varies directly" into a proportion, which is two fractions equal to each other:

x/y = x/y

Fill in the three numbers given and cross multiply and solve to find the fourth number. See image.
