It would be -145 if its below sea level.
Answer:
37.5%
Step-by-step explanation:
15 (total number of correct answers)
divided by
40 (total questions)
= 0.375
you now want to mltiply by 100
0.375 x 100
37.5
therefore Bernie has a percentage of 37.5% or when rounded, he has a 38%.
A= adult ticket c=child ticket
1. 6a+4c=88
12a+9c=186
2. so you need to multiply the top number by -2 so you can cancel out the 12a
-2(6a+4c=88)=. -12a-8c=-176
3. then you add them all together
12a+9c=186
-12a-8c=-176
——————————-
c=10
4. now you have to find ‘a’
6a+4(10)=88
6a+40=88
-40. -40
6a=48
divide both sides by 6
a=8
And your final answer should be (8,10)
