Andreas93 [3]

Answer:

j=1/2k+5/2

Step-by-step explanation:

2j−k=5

Step 1: Add k to both sides.

2j−k+k=5+k

2j=k+5

Step 2: Divide both sides by 2.

2j/2=k+5/2

j=1/2k+5/2

3x - 2 = x + 1
2x = 3

x = 1.5

3x - 2 = 3(1.5) - 2 = 2.5
or
x + 1 = 1.5 + 1 = 2.5

P = 4(2.5) = 10

perimeter of square is 10 cm so side of square = 2.5cm
