A+b=100
a-b=6 ⇒ a= b+6
(b+6)+b=100
2b+6=100
2b=100-6
2b=94
b=94:2
b=47
a=47+6
a=53
Answer:
15 square feet
Step-by-step explanation:
Multiply 1.5 by 3 which equals 4.5
Multiply 1.5 by 2 which equals 3
Add the above answers (4.5 plus 3)
Then multiply by 2 (7.5 times 2)
It equals 15
I hope this helps and that this is the right problem. There is no picture shown but I just did this problem for someone else so I thought I would take a shot at it :)
If it is division then it would be
![\frac{5}{3} = \frac{3}{5}](https://tex.z-dn.net/?f=%20%5Cfrac%7B5%7D%7B3%7D%20%20%3D%20%20%20%5Cfrac%7B3%7D%7B5%7D%20%20)
which would be false but since I could not determine if it is division or multiplying
if multiplying it would be
![5 (3) = 15 = 3(5) = 15](https://tex.z-dn.net/?f=5%20%283%29%20%3D%2015%20%3D%203%285%29%20%3D%2015)
which would be true
![31250 \div 500 = 62.5](https://tex.z-dn.net/?f=31250%20%5Cdiv%20500%20%3D%2062.5)
![31250 \div 250 = 125](https://tex.z-dn.net/?f=31250%20%20%5Cdiv%20250%20%3D%20125)
![31250 \div 125 = 250](https://tex.z-dn.net/?f=31250%20%20%5Cdiv%20125%20%3D%20250)
![31250 \div 175 = 178.5](https://tex.z-dn.net/?f=31250%20%5Cdiv%20175%20%3D%20178.5)
The model should be scaled so that 1 centimeter equals 250 miles.
All 20-22 are equal to 1
