If you would like to simplify 3 * u^2 + 21 * u^2, you can calculate this using the following steps:

3 * u^2 + 21 * u^2 = (3 + 21) * u^2 = 24 * u^2

The correct result would be 24 * u^2.

What is X? x divided by 4/9 = 9/10
Damm [24]

Answer:

2/5

Step-by-step explanation:

\frac{x}{\frac{4}{9} } =\frac{9}{10}

(\frac{9}{10})(\frac{4}{9} )=\frac{36}{90}

36 divided by 90 is 2/5.

When solving for X you do the opposite to a number if you are moving it to the other side of the problem. so, since x is being divided by 4/9, 4/9 would be multiplied to the opposite or to the 9/10.

How can you use distributive property to find 3/4 times 2 and 1/3
zubka84 [21]

Answer:

1 3/4

Step-by-step explanation:

You can set it up like the distrubtive property first

3/4(2+ 1/3)    Next you use the distirbutive property instead of adding inside the parenthesis and you multiply the 3/4 by 2 and then the 3/4 by 1/3

Use 2 as 2/1 in fraction problems

3/4 * 2/1        Now multiply the numerators together and the denomenators together

3 * 2 = 6          4 * 1 =4

6/4

3/4 *1/3

3 * 1 =3

4 * 3 =12

3/12

Now we have to make them both like terms (same denominator) so we can add them, we will multiply the 6/4 by 3 (Both top and bottom)

6 * 3 = 18               4 *3 =12

18/12

Now we add the fractions

3/12 +18/12 = 21/12

Reduce that and you get

21/12 = 1 9/12  or 1 3/4
