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
Answer:
d= 90 degrees
e= 99 degrees
f= 81 degrees
Step-by-step explanation:
To find d, you know that the other side is equal to 90. Because two sides that are opposite of each other must be equal to 180, you do 180-90 which is 90 to get d. Therefore, d=90 degrees. 99 degrees and e are alternate interior angles so that means they have to be the same. Because f is on the other side of 99 degrees and two sides that are opposite of each other must equal 180 degrees, you have to do 180-99 which is equal to 81 degrees. Therefore, d=90 degrees, e=99 degrees, and f=81 degrees
