One number is four more than four times another. if their sum is decreased by six, the result is twenty-eight. find the numbers.

let "one number" = x, and "another" = y

x = 4y + 4

(x + y) - 4 = 28

Plug in 4y + 4 for x

4y + 4 + y - 4 = 28

Simplify. Combine like terms

5y = 28

Isolate the y. Divide 5 from both sides

y = 28/5

y =  5.6

Plug in 28/5 for y.

x = 4y + 4

x = 4(28/5) + 4

Simplify

x = 22.4 + 4

x = 26.4

x = 26.4, y = 5.6

hope this helps

step-by-step explanation:

divide 13.5 by 9 to get the scale factor. it equals 1.5

2 * 1.5 = 3

b because it contains 40% of the possible results from the random list.  

0,1,2,3 v 4,5,6,7,8,9  

4 integers to 6 integers  

40% success vs 60% fail
