Answer:
a = 195 ; c = 615
Step-by-step explanation:
So, you want to start by forming your equations...
I will use 'c' for children and 'a' for adults for my variables
3a + 30 = c
(this is because of the info that 30 more tickets than 3 times the amount of children's were sold than adult)
then for equation 2:
3c + 5a = 2820
(this is because of the prices of the tickets and the total money raised)
Then, plug in the equation for c
Your equation should look like:
3(3a + 30) + 5a = 2820
You get:
(9a +90) + 5a = 2820
Then:
14a = 2730
So:
a = 195 adult tickets sold
Plug in a, to find c:
3 (195) + 30 = c
585 + 30 = c
c = 615 children tickets sold
b
Step-by-step explanation:
x
Answer: -x because its more than one zero
Step-by-step explanation:
F(g) = 4g+6
1. when g = 2, output f(2) = 14
answer: 14
2. output = 18
18 = 4g+6
4g = 12
g = 3
answer: 3
3.when g = 4
f(4) = 16+6=22
answer
(4,22)
4. when input = 6 means g=6
f(6) = 24+6 = 30
different = 30-6 = 24
answer: 24
P=2l+2w ---> P=2(11)+2(8.5) -- Substitute
P=2(11)+2(8.5) ---> P=22+17 -- Multiply
P=22+17 ---> P=39 inches -- Add
