answer:
the number is one
work:
let's analyze the question.
15 times a number is..
so, right away we have 15n.
.... decreased by eight...
we are subtracting 8, so 15n - 8
...the result is 17.
so, 15n - 8 will equal 17.
Find the number.
now, we solve for n.
15n - 8 = 17 (add 8 to both sides)
15n = 15 (divide both sides by 15)
n = 1
so, the number is one. hope this helps, have a great day!
