Make two equations
C = children, A = adults
2.50C + 7.00A = 7950
(C + A = 2100) * 2.5
2.50C + 2.50A = 5250
Use elimination
4.5A = 2700, A = 600
2100 - 600 = 1500
Solution: 600 adults, 1500 children
Answer:
5
Step-by-step explanation:
10,000,000÷2,000,000=5
(1x10^7)÷ (2x10^6) = 5
To find the answer make 25 equal to 6x+1
25=6x+1
25-1=24
24=6x
24/6=4
x=4
X=4
