1.) 9 more than 1/2 the number no more than -8.
n = number
n + 9 = nine more
1/2 n = half the number
no more than -8 (means) <= -8
1/2 n + 9 <= -8
1/2 n <= -17
Multiply both sides by 2
n <= -34
number is 34 (less than or equal -34)
2.) h hours at rate of 55 mi/hr
D = RT (Distance = Rate x Time)
h = hours
55h = h hours at 55 mph
Did not reach goal of 385 (means) < 385
55h < 385
h < 7
Drove 7 hours (less than 7 hours)
Write then solve the inequality.
1. nine more than half the number n is no more than -8. Find n.
