Answer:
12+3-4+1=12
Step-by-step explanation:
Answer:
0.2
Step-by-step explanation:
If the arrow points to the smaller rectangle this means the square reduced size
![sf=\frac{0.5}{2.5}](https://tex.z-dn.net/?f=sf%3D%5Cfrac%7B0.5%7D%7B2.5%7D)
![sf=0.2](https://tex.z-dn.net/?f=sf%3D0.2)
Another way to look at it is that the rectangle was reduced in a factor of 5 (1/0.2=5)
Integers
positive
okso therefor
3x=some number
4y=some number
7y=some number
therefor, this 'some number' must have factors of 3,4,7
find greatest common multiplule
3=3
4=2 times 2
7=7
3 times 2 times 2 time s7=84
3x=4y=7z=84
solve
3x=84
divide 3
x=28
4y=84
divide 4
y=21
7y=84
divide 7
y=12
so
x+y+z=28+21+12=61
