Any four sided shape with parallel sides and parallel top and bottom is a quadrilateral called a rectangle. A more narrow definition is then those with equal side lengths are called squares.
What do you mean?.. Do you mean: e.g. How many tens are in 12.476? So you basically have the 70 as ten right? Well you need to count from the first number (12). So the answer to that example would be 1247. Forget about the decimal point.
Answer:
y=2
Step-by-step explanation:
2y + 8y - 20 = 5 (y -2)
Combine like terms
10y -20 = 5(y-2)
Divide by 5
10y/5 -20/5 = 5/5(y-2)
2y -4 = y-2
Subtract y from each side
2y-y -4 =-2
y -4 = -2
Add 2 to each side
y-4+4 =-2+4
y =2
