Answer:
22,440
Step-by-step explanation:
204 = 2 * 2 * 3 * 17
1320 = 2 * 2 * 2 * 3 * 5 * 11
They both have 2 2's and a 3 in common, so use them once
2 * 2 * 3 * 17 * 2 * 5 * 11 = 22,440
Answer:
258
Step-by-step explanation:
Set up the two equations needed (x is the adult tickets and y is the student tickets)
x+y=372
6x+2y=1776
Solve by elimination
-2(x+y=372)
=-2x-2y=-744
Cancel like figures:
-2x-2y=-744
6x+2y=1776
= 4x=1032
x=258
Using how tall it is over how wide
=>tall/wide
The model 15in/1.5in
The actual x/55ft
Convert everything into the same units so 55ft to inches
There are 12in in 1ft
55ft * 12in/1ft
The ft cross out leaving in
55*12in= 660 in
So
15in/1.5in = x/660in
Now solve for x my multiplying both side by 660in
660in *15in/1.5in=x
x= 6600in tall
11 / 12 - 8 / 12 = 3 / 12 = 1/4 square meters;
