Solve for x: 2/7(x-2)=4x

Mathematics
1 answer:
lawyer [7]3 years ago

Answer:

x =  -  \frac{2}{13}

Step-by-step explanation:

Simplify to:

\frac{2(x - 2)}{7}

Multiply both sides by 7

2(x-2)=28x

Divide both sides by 2

x-2=14x

Subtract x from both sides

2=14x-x

Simplify 14x-x to 13x

2=13x

Divide both sides by 13

-  \frac{2}{13}  = x

Answer:

x =  -  \frac{  2}{13}

your planning to build a boat. you have a sample board of wood that you want to use . the board has an area of 1/3 ft squared an
frosja888 [35]
Given:
Area of sample board: 1/3 square ft.
Weight of sample board: 1/5 lbs

We need to get the weight of the whole square foot.

1/3 square foot is only a part of the whole square foot. Its corresponding weight is 1/5 pounds. We need to divide the area by its corresponding weight to get the total weight per square foot.

1/3 ÷ 1/5 

Rules of dividing fractions:
1st fraction: 1/3 ; 2nd fraction: 1/5

1) Get the reciprocal of the 2nd fraction. 1/5 ⇒ 5/1

2) Multiply 1st fraction to the reciprocal of the 2nd fraction
1/3 * 5/1 = 5/3

3) Simplify fraction.
5/3 is an improper fraction. To simplify it, it needs to become a mixed fraction.

5/3 = 1 2/3 pounds.
