Question

solve the inequality 0 ≤ ((x+7)/2) < 9

Answer 1

Well....we don't want a fraction in the middle.....so we should multiply everything by 2...this will eliminate the fraction

0 ≤ ((x+7)/2) < 9
*2 *2 *2

0 ≤ x + 7 < 18

now we want solve for 'x'....so we should subtract 7 from everything as well...this will completely isolate x in the middle

0 - 7 ≤ x + 7 - 7 < 18 - 7

? ≤ x < ?

Answer 2

\[-7\le x < 11\]

Answer 3

That would be correct!
