257 1/2 should be the correct answer
(a) He would drive 96 km in an hour because 1152 divided by 12 is 96
(b) He is technically on schedule because he is driving 104 km per hour, instead of 96, so if he keeps driving at the same rate, he should get there in under 12 hours
Answer: One solution
Step-by-step explanation:
Given
-5x-8=8
Add 8 on both sides
-5x-8+8=8+8
-5x=16
Divide -5 on both sides
-5x/-5=16/-5
x=-3.2
Therefore, it has one solution
Hope this helps!! :)
