Answer:

90

Step-by-step explanation:

10x - x = 81

9x = 81

x = 9

larger number = 10 x 9 = 90

For this case we have that "x" is the variable that represents the smallest number to find. Let and the variable that represents the largest number, then:y = 10x\\y-x = 81

Substituting the first equation in the second:

10x-x = 81\\9x = 81\\x = \frac {81} {9}\\x = 9

So, the biggest number is:

y = 10 * 9 \\y = 90

Answer:

10x

90

vladimir1956 [14]
Hey there,
2 hours = 15 pages
1 hour = 15 / 2
           = 7.5 pages
15 pages = $40
1 page = $40 / 15
            = $2.666666666666667
7.5 pages= $2.666666666666667 x 7.5
               = $20

Hope this helps :))
