Answer:
n ≥ -9
Step-by-step explanation:
Let n = the number
8 <em>less than</em> a number means "n – 8", but
8 <em>less</em> a number means "8 – n," so
8 – n ≤ 17 Subtract 8 from each side
-n ≤ 9 Multiply each side by -1
n ≥ -9
<em>Note</em>: When we multiply by a negative number, we must reverse the inequality.
<em>Check:</em>
Try n = -8.
8 – (-8) ≤ 17
8 + 8 ≤ 17
16 ≤ 17
<em>True</em>.

Answer:
Adult’s ticket = $ 18
Child’s ticket = $ 16
Step-by-step explanation:
Adults: x
Children: y
(3x + 4y = 118) * (2) = 6x + 8y = 236
(2x + 3y = 84) * (-3) = -6x - 9y = -252
Add both equations:
-y = - 16
y = 16
3x + 4(16) = 118
3X + 64 = 118
3X = 118 - 64
X = 54/3=18
