parallel line: m1 x m2 = -1
-3 x 1/3 = -1
Answer:
a) x = 24
b) x = 20
Step-by-step explanation:
a) x÷3 - 2 = 6
+2 +2
x÷3 = 8
×3 ×3
8 × 3 = 24
x = 24
b) x÷5 + 1 = 5
-1 -1
x÷5 = 4
×5 ×5
4 × 5 = 20
x = 24
Answer:
25 inches
Step-by-step explanation:
If square has a perimeter of 20 inches, the length of each side is:

After cutting the square in half, we are left with two rectangles of 5 in x 2.5 in
Attaching those two smaller rectangles by their short end (2.5 in side), gives us a new rectangle with a height of 2.5 in and a length of 10 in (sum of the 5 in sides in each rectangle). The perimeter of this new rectangle is:

The perimeter is 25 inches.
