Answer:
237
Step-by-step explanation:
This is a system of equations.
The theater sold 364 adult and child tickets, so a + c = 364
They made a total of $1930. Each adult ticket was $6 & child tickets were $4. The second equation is 6a + 4c = 1930.
Let's line them up
a + c = 364
6a + 4c = 1930
Since we need to solve for the number of adult tickets, we want to get rid of the c variable. I'm going to multiply the entire first equation by -4 to do this. The second equation stays the same. Now, I have:
-4a - 4c = -1456
6a + 4c = 1930 Add them together
----------------------
2a = 474 Divide by 2 to solve for a
a = 237
There were 237 adult tickets sold
187 cm squared.
Based on rectangle:
2L + 2W = 56
Draw the square and name your sides the following:
(W+4) , (L-2), (W+4), (L-2)
Because it’s a square, all sides are equal and we can remove and solve for one of the variables but keep in mind the parameter changed..
The new parameter is 56 minus 4cm + 8cm...keep in mind I used 4cm and 8cm because we have a 2 Lengths and 2 Widths.
Solving 60= 4 (w+4)
W= 11
So the side of our square is 11+4=15
L-2 = 15
L=17
So the area of the Rectangle is 11*17=187 cm squared.
Please let me know if it’s correct !

Answer: 45
Step-by-step explanation:
When multiplying by 10^2 you first multiply 10 by itself twice like 10x10=100 and then multiply .45x100=45 because multiplying by 100 simply moves the decimal place over twice to the right
Answer:
25$
Step-by-step explanation:
If 4 stickers cost 2$, then each sticker would cost .50$
50(.5)=25
You would have spent 25$
