What is the valuable of x in the equation 1.8-3.7x=-4.2x+0.3

Mumz [18]

Answer:

x = 3

Step-by-step explanation:

1.8 - 3.7x = -4.2x + 0.3

add -4.2x to both sides

1.8 - 0.5x = 0.3

subtract 1.8 from both sides

-0.5x = 0.3 - 1.8

-0.5x = -1.5

divide by -0.5 on both sides

x = 3

we know that

The perimeter of rectangle is equal to

$P=2L+2W$

In this problem we have

$P=42\ m$

$42=2L+2(6)$

simplify

$21=L+(6)$

$L=21-6=15\ m$
