What is the solution to the inequality? 17 < 9 + x
2 answers:
17 < 9 + x Subtract 9 from both sides.
17 - 9 < 9 - 9 + x
8 < x
Be very careful that you leave the open end of the less than symbol pointing towards the x It means that x is greater than 8.
You could write it the other way x > 8 but the pointy end must always be closest to the 7 which is another way of saying what the answer means.
Notice anything after the 8 going right is colored and it is the answer.

Answer:
<em>29 minutes more</em>
Step-by-step explanation:
Let m represent minutes
changing the statement to algebra, since the second company charges a different rate at night and weekend we have the equation below;
$19.99 + $0.35m > $29.99
Subtract 19.99 from both sides to isolate m and we have;
$19.99 -$19.99 + $0.35 > $29.99 - $19.99
= $0,35m > $10.00
Divide both side by 0.35 to obtain the value of m;
>
= m > 28.57
<em>m ⩾ 29 minutes</em>
<em>The second company's will be twenty nine minutes or more costlier than the first company</em>
