Explain in sentences how you can add or subtract two fractions with common denominators?

If two fractions have the same denominators, then just simply add up the numerators together and keep the denominator.

Examples:

\frac{4}{10} +  \frac{5}{10} =  \frac{9}{10}

\frac{10}{12} - \frac{2}{12} = \frac{8}{12}

At what value of x do the graphs of the equations below intersect?
Bogdan [553]

Answer:

Step-by-step explanation:

The intersection is the point where two equations meet. It is calculated by substituting terms into the equations involved. For the given systems of equation, calculations are as follows:

2x - y = 6

y = 2x - 6

We substitute the equation above to the second equation.

5x + 10y = –10

5x + 10( 2x - 6 )= –10

Simplifying, 

5x + 20x - 60 = -10

25x = 50

x = 2

Therefore, the intersection has the value of x equal to 2.

Follow the steps to solve for the variable in this two-step equation:
lesya692 [45]

The solution of the equation is x = 2

Step-by-step explanation:

The original equation is

5x-10 = 0

We solve it using the following steps:

1) We apply the addition property of equality: by adding the same factor on both sides of the equation, the equation does not change.

In this case, we add +10 on both sides, and we get:

5x-10+10=0+10\\5x=10

2) We apply the division property of equality: by dividing both sides of the equation by the same number (different from zero), the equation does not  change.

In this case, we divide both sides of the equation by 5, and we get:

\frac{5x}{5}=\frac{10}{5}\\x=2

Therefore, the solution of the equation is x=2.
