61 should be correct
Simora [160]3 years ago
6 0

Answer:

61

Step-by-step explanation:

let the number be x then twice the number is 2x, hence

42 + 2x = 164 ( subtract 42 from both sides of the equation )

2x = 122 ( divide both sides by 2 )

x = 61

Hence the number is 61

The length of a rectangle is five times its width.
Vera_Pavlovna [14]

Answer:

72

Step-by-step explanation:

l = 5w

A = l*w

180 = 5w *w

180 = 5w^2

Divide each side by 5

180/5 = 5w^2 /5

36 = w^2

Taking the square root of each side

sqrt(36) = sqrt(w)^2

6 =w

l = 5w = 5*6 = 30

The perimeter is

P = 2(l+w)

P = 2(6+30) = 2(36) = 72
