the number=A

5xA/7+A=2

5A/7 +A =2

5A/7=2-A/1

7(2-A)=1(5A)

14-7A=5A

14=5A+7A

14/12=12A/12

A=14/12

A=7/6

Twice the difference of a number and 5 is 2.<br> Use the variable W for the unknown number
Kitty [74]
Hey there!

The difference of a number, w, and 5 will be represented by (w – 5). Twice this would simply multiply this expression by 2, making it 2(w – 5). Finally, just set this expression equal to 2. Your equation is 2(w – 5) = 2. 

To solve this, expand the two to the terms in parentheses. Then, solve the rest of the way as you would normally, using addition, subtraction, multiplication, or division to cancel out and move around terms. Remember, what you do on one side must be done to the other!

2(w – 5) = 2
(2*w – 2*5) = 2
(2w – 10) + 10 = (2) + 10
(2w) ÷ 2 = (12) ÷ 2
w = 6

Hope this helped you out! :-)

Solve for the indicated variable. Include all of your work in your answer. Submit your solution.

P = 2L + 2W
factor out 2 from right side
P = 2(L+W)
Divide both sides by 2

P/2 = L + W
subtract W from both sides

L = P/2 - W

a rectangle has an area of 7/8 square units if the width is 7/16 unit what is the length of the rectangle in units?
djyliett [7]

Answer:

Length=2 units

Step-by-step explanation:

Given :

Area of the rectangle =\frac{7}{8}  square units

Width of the rectangle=\frac{7}{16} units

Area of the rectangle= Length* Width

                         \frac{7}{8} =Length*\frac{7}{16}

Multiplying  \frac{16}{7} both the sides

                      \frac{7}{8} *\frac{16}{7} =Length

                     Length=\frac{16}{8}

                   Length=2 units

The length of the rectangle is 2 units
