100-20 round the last numbers so they have a 0 at the end so 4 or under is 0 and 5 or higher is 10 so 100 - 20 is 80
Answer:
Perimeter of square Q is 49 inches.
Step-by-step explanation:
Let x be the length of side of square P and y be that of square Q.
It is given in the question that :

Also it is given that x=3.5 inches.Hence

∴ y=12.25 inches.
Perimeter of square Q is 4y =
inches.
Answer: x=5
Step-by-step explanation:
If you break the fraction into a whole number it would be 5 and 10 minus 5 is 5. so x=5
Move 6x to the right side: 2y=12-6x
Divide both sides by 2: y=6-3x
m is the slope which in this case is -3
