Answer:
let the number of race entries be x
55x+10,000-15x =55000
55x-15x=55000-10000
40x=45000
x = 500
It must receive 500 race entries.
Step-by-step explanation:
Answer: 2(2x+4y)
Step-by-step explanation:
4(x+2y) would be simplified to 4x+8y, so you just have to make an expression that would get you that answer.
Answer:
Adult tickets = 84
Children tickets = 33
Step-by-step explanation:
At a play 117 tickets were sold.
Adult's tickets (a) cost $2.50 each and,
Children's (c) tickets cost $1.00 each
Money collected = $243
This is the simultaneous equation formed:
a + c = 117 ... (i)
2.5a + c = 243 ... (ii)
Subtracting (ii) - (i) we get;
1.5a = 126
a = 126 ÷ 1.5 = 84
So there were 84 adult's tickets sold and 117 - 84 = 33 children's tickets sold.
