Question

write an inequailty for the sentence. Then solve th inequality..
Fifteen less than a number is at most 6.

Answer 1

"Fifteen less than a number" is the same as subtracting 15 from an unknown number, 'x'.

"at most" is less than or equal to.

So we have:

$\sf~x-15\le6$

Add 15 to both sides:

$\sf~x\le21$
