3 + (-8) - 17
3 - 8 - 17
3 - 25
-22 <==
Answer:
Step-by-step explanation:
5(3g-2)+8=58
5(3g-2)=58-8
5(3g-2)=50
3g-2=50/5
3g-2=10
3g=10+2
3g=12
g=12/3
g=4
-----------------
7x-(4x-15)=13
7x-4x-(-15)=13
3x+15=13
3x=13-15
3x=-2
x=-2/3
He will get no solutions and this is for the following reasons:
1. A and B have no solutions, so they must be parallel.
2. B and C have infinite solutions, so they must represent the same line.
Answer:
192 children and 145 adults were admitted.
Step-by-step explanation:
Let c represent the amount of children and let a represent the amount of adults.
Total fees for children = (Fee for one child) x (Amount of children) = 6.5c
Total fees for adults = (Fee for one adult) x (Amount of adults) = 15a
Total fees = Total fees for children + Total fees for adults
3423 = 6.5c +15a
We know that the amount of people who entered the park was 337. Therefore a+c=337, which means a=337-c.
Sub this in to the equation above to get:
3423 = 6.5c +15 (337-c)
3423 = 6.5c + 5055 - 15c
-1632 = -8.5c
c = 192
So there were 192 children.
Since a=337-c and c=192, a=337-192=145. So there were 145 adults.
