3 1/8 means 8 x 3 + 1 = 25/8
Step-by-step explanation:
4/5 x 25/8
= 4x25/5x 8
= 100/40
= 5/2
The perimeter because the fence goes AROUND the yard, not in it.
P = 2w + 2l
P = 2(60) + 2(20)
P = 120 + 40
P = 160
Charlene needs 160 meters of fencing material.
76 cm,
(4•10=40)+((10-4)•6)= 76 units
You divide the difference of the y-coordinates of 2points on a line by the difference of the x-coordinates of the same 2points
<span>The answer to this question is Step 7.
Step 7 ⇒ −8 + 10 = x
− 10 + 10
This is where 10 is being added to both sides. It is not Step 4 as that uses the Subtraction Property of Equality (which can be proved true by taking the addition of a negative number).
