Answer:
P=18
Step-by-step explanation:
The formula given is P=2L+2W
so, multiply the length and width by 2:
6×2=12
3×2=6
now, add 6 and 12:
6+12= <u>18</u>

Answer:
15.3 in
Step-by-step explanation:
The lengths are proportional, so you can write ...
model/train = 3 in/(35 ft) = (x in)/(178.5 ft)
Multiplying by 178.5 ft, we get ...
x in = (3 in)(178.5/35) = 15.3 in
The length of the model is 15.3 inches.
Area=lw
l=2w
aera=2l^2
72=area
72=2l^2
divide both sides by 2
36=l^2
sqrt both sides
6=l
length=6 units
Answer: 40 tickets.
Step-by-step explanation:
Let's call:
x: the number of child tickets sold that day.
y: the number of adult tickets sold that day.
Based on the information given in the problem, you can make the following system of equations:
![\left \{ {{y=3x} \atop {6.20x+9.40y=1376}} \right.](https://tex.z-dn.net/?f=%5Cleft%20%5C%7B%20%7B%7By%3D3x%7D%20%5Catop%20%7B6.20x%2B9.40y%3D1376%7D%7D%20%5Cright.)
You must use the method of substitution to solve the system of equations:
Substitute y=3x into the second equation and solve for x:
![6.20x+9.40y=1376\\6.20x+9.40(3x)=1376\\6.20x+28.2x=1376\\34.4x=1376\\x=40](https://tex.z-dn.net/?f=6.20x%2B9.40y%3D1376%5C%5C6.20x%2B9.40%283x%29%3D1376%5C%5C6.20x%2B28.2x%3D1376%5C%5C34.4x%3D1376%5C%5Cx%3D40)
Then the answer is: 40 tickets.
0.015 or 3/200
15 divided by 1000 is 0.015
15/5 is 3 1000/5 is 200
