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
Aaron's plane flew 2.25 cm More than noah's plane
Answer:
-11
Step-by-step explanation:
First we plug -2 in for c
4(-2)-3=-8-3=-11
It is equivalent to 23/99 but not for the rest.
As the denominator gets larger, the decimals gets smaller.
eg. 23/999 = 0.023232323...
As you can see , it is 0.02 now so it is not equivalent to 0.232323 as it is 0.2
False, since it we substitute x = 4 into the equation we get y = -4 + 3 = -1
