Meaning you don't have to solve the equation in a certain order just left to right in order to find the answer unlike division and subtraction
Answer:
70 yards.
Step-by-step explanation:
50% is also 1/2, so you put 140/2, and get 70.
I think that 3 rolls is wrong and that 6 rolls is right. If you create a 15 by 15 square and draw two lines through the center that connect to the opposite corner, you'll be able to use the Pythagorean Theorem.
Perimeter: 15+15+15+15=60ft.
Length of Line from Corner to Corner:
(15)(15)+(15)(15)=C^2
225+225=C^2
450=C^2
21.2=C
21.2(2)= 42.4ft.
42.4ft.+60ft.= 102.4ft.
102.4ft. divided by 20ft. = 5.12 = <u>6 rolls</u>
Answer:
-16
Step-by-step explanation:
