Answer: 475 adults paid admission
Step-by-step explanation:
1.50c+4a=5050 (1.50 per child and 4 per adult)
1.50(2100)+4c=5050 (2100 children times 1.5 each)
3130+4a=5050
4a=1900
a=475
Answer:
76 degrees
Step-by-step explanation:
GE = 180 since it is a straight line
GE = GR + FE
180 = 7x+6 +6x-8
Combine like terms
180 = 13x-2
Add 2 to each side
182 = 13x
Divide by 13
182/13 = 13x/13
14 =x
We want FE
FE = 6x-8
FE = 6(14) -8
=84 -8
=76
Count the negative signs, if you get an odd number of negative signs, the product is a negative. If you get an even number of negative signs, the product is a positive.
in this case, there are two negatives, the the product is a positive number
