Solve for this equation. x-2/5=1/5

Studentka2010 [4]

Answer:

3/5 or

0.6

Step-by-step explanation:

You could change these fractions to decimals, but you may not be convinced that the answer you get is the same as just using fractions. I'll start by using fractions.

x - 2/5 = 1/5 Add 2/5 to both sides

x - 2/5 + 2/5 = 1/5 + 2/5 The left side cancels to 0.

x = 1/5 + 2/5 The denominators (bottom the fraction) are the same. Just add the tops.

x = (1 + 2)/5

x = 3/5

=======================

If you use your calculator to find 2/5 and 1/5, you can get the same answer as 3/5

0.4

By the same method, 1/5 = 0.2

Substitute into the original equation

x - 0.4 = 0.2 Add 0.4 to both sides

x - 0.4 +0.4 = 0.2 + 0.4 The left side reduces just to x

x = 0.2 +0.4

x = 0.6

If you let your calculator do the work, like this

0.6

The answers are the same.

I need to find the area of the shaded region, but I need detailed steps

olasank [31]

The shaded region is a parallelogram.

The formula for the area of any parallelogram is $A=bh$ .

The base of the parallelogram is 2 meters long (given).

The height of the parallelogram is 9 meters (do not be fooled by the unnecessary information of 14 meters)
The height is 9 meters because the height has to be perpendicular to the base. Thus, the side length must be 9 meters.

Multiply them together.

$2 \times 9 = 18$

The area of the parallelogram is 18 square meters.
