One number is 10 times as large as another, and their difference is 81. find the numbers. if x represents the smaller number, then the larger number is1010xx - 10

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:

Substituting the first equation in the second:

So, the biggest number is:

10x

90

answer: approximately 206 bones

i hope this u out a branlist and a would be greatly appreciated :

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
