Answer:
185 adults and 184 children
Step-by-step explanation:
People entering the park = adults plus children
369 = a+c
Total money = admission fee for kids * number of children + admission fee for adults * number of adults
1671 = 3.25c + 5.80a
We have 2 equations and 2 unknowns
Solve the first equation for a by subtracting c from each side
369-c = a+c-c
369-c =a
Substitute this in to the second equation
1671 = 3.25 c +5.80 (369-c)
Distribute the 5.8
1671 =3.25c +5.8*369 - 5.8c
1671 = 3.25c +2140.2-5.8c
Combine like terms
1671 = -2.55c +2140.2
Subtract 2140.2 from each side
1671-2140.2 = -2.55c +2140.2-2140.2
-469.2 = -2.55c
Divide by -2.55 on each side
-469.2/-2.55 = -2.55c/-2.55
184 =c
There were 184 children
Now we need to find a
369 = a+c
369 = a+184
Subtract 184 from each side
369-184 = a+184-184
185 =a
There were 185 adults
I believe that the answer is B 17

Answer:
1) 45 degrees
2) 75 degrees
3) 37 degrees
4) 43 degrees
5) 137 degrees
Step-by-step explanation:
1) Angle 1 is equal to the 45 degree angle above it, so we know it is 45 degrees
2) All triangles are 180 degrees. Angle 2 = 180 - 60 - Angle 1 = 180 - 60 - 45 = 75
3) These three angles = 180 degrees. 180 - 68 - Angle 2 = 180 - 68 - 75 = 37
4) All triangles are 180 degrees. 180 - 100 - Angle 3 = 180 - 100 - 37 = 43
5) 180 - Angle 4 = 180 - 43 = 137
Answer:
Yes!
Step-by-step explanation:
Yes, because 2>1.
