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}

What is 7/10 + 7/10 =
Nonamiya [84]

The correct answer is 1.4 or 1 4/10

I did this by turning 7/10 into a decimal which is 0.7.

Now I just add 0.7 + 0.7.

For that equation i got 1.4

This would equal 1 4/10

HELPP 30 POINTS A bag of marbles has a mass of 45 grams. What is the mass of 250 bags of marbles in kilograms?
Leto [7]

Answer:

11.25 kg

Explanation:

1 bag of marbles → 45 grams

250 bags → (45 *250) = 11250 grams

Conversion:

1 kg ↔ 1000 grams

So,

11250 g → (11250/1000) kg = 11.25 kg

What is the quotient (x3 – 3x2 + 5x – 3) ÷ (x – 1)?
NeTakaya

Answer:

The quotient of the expression will be (x² - 2x + 3).

Step-by-step explanation:

The given expression is (x³ - 3x² + 5x - 3) ÷ (x - 1)

Now we will use the synthetic division method to solve this question.

We will note down the coefficient of the expression as below

                         x³               x²            x               constant

                         1               (-3)            5                   -3

                 1       1       (1×1-3)=(-2)   [1×(-2)+5]=3     (1×3-3)=0

Therefore (x -1) is a perfect zero factor.

Now we can easily say that coefficient of the expression is [1.x² + (-2)x + (3)]

and remainder is 0.

Or in more simplified way coefficient of the expression will be

(x² -2x + 3).

Write the equation of a line that passes through the point m(2,3) and has slope 1/2.
denis-greek [22]

Answer:

Step-by-step explanation:

Equation \ of \ a \ line,  (y-y_1)=slope(x-x_1)

(x_1, y_1) = (2,3)

                                y-3=\frac{1}{2}(x-2)\\\\y -3= \frac{1}{2}x-1\\\\y = \frac{1}{2}x-1+3\\\\y = \frac{1}{2}x+2
