Answer: x = 5

Step-by-step explanation:

1. Set the two given expressions equal to each other (because the problem says they are interchangeable)

-5x = -40+3x

2. Subtract 3x from -5x to have x on one side of the equation.

-8x = -40

3. Divide each side by -8 to get the value of x.

x = 5

To find the perimeter of this blue figure, add together the shown lengths of the six sides.  

The three measurements on the top have the LCD 4, so we combine 14 3/4, 4 2/4 and 8 2/4.  The sum is 26 7/4, or 27 3/4, or 27.75.

The three measurements on the bottom share the LCD 5, so we can immediately combine them, obtaining 32 8/5, or 33 3/5, or 33.60.

Combining 27.75 and 33.60 results in 61.35, or 61 35/100, or 61 7/20.

The perimeter of the given figure is 61 7/20.

I am an improper fraction whose numerator and denominator are made of odd digits only. In my simplest form, my representation as
ASHA 777 [7]

Answer:

The fraction is =  \frac{21}{9}

Step-by-step explanation:

In simplest form the fraction is represented in mixed number as 2\frac{1}{3}.

The fraction form of the mixed number can be given as :

2\frac{1}{3}=\frac{7}{3}

Let the fraction be = \frac{7x}{3x} [As multiplying same numbers to numerator and denominator does not affect the proportion.

Sum of numerator and denominator is = 30

This, can be represented as:

7x+3x=30

Solving for x.

10x=30

Dividing both sides by 10.

\frac{10x}{10}=\frac{30}{10}

x=3

So, the fraction will be = \frac{7\times 3}{3\times 3}

⇒ \frac{21}{9}

What is c/22 + 668 = 684 I NEED HELP!!!!!!!!!!!!!!
scoundrel [369]

Answer:

352

Step-by-step explanation:

So first you need to subtract 668 from both sides.

c/22 + 668 = 684

          -668  -668

---------------------------

c/22 = 16

Then multiply both sides by 22.

c/22 * 22 = 16*22

c = 352

Check-

352/22=16

16+668=684
