One number is 8 times another number. the numbers are both positive and have a difference of 70. find the number

the anwer would be 560 cause it says 8 times anthor number so 70 times 8 would be the anwer so ya.

With questions like these you must use the information you get to form equations which model your problem.

I'll use these variable in my equation:

- B = big number

- s = small number

B - s = 70 <- big number is first since the difference is positive

B = 8s. <- One number is 8 times another number, well it wouldn't make sense if the smallest number is 8 times the biggest number. So we know it must be B that is 8 times "s".

I can substitute what I have in the second equation for B in the first.

8s - s = 70.

7s = 70

7s/7 = 70/7

s = 10.

So the small number is 10.

B = 10*8

B = 80.

And the big number is 80.

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.
