Answer:

C and D, x = 5

Step-by-step explanation:

To solve this problem, you add 9.2 to both sides then divide both sides by 5.5. The Addition Property of Equality states that if two expressions are equal to each other, and you add the same value to both sides of the equation, the equation will remain equal. This is the first step to solve the problem. The Division Property of Equality states that when we divide both sides of an equation by the same non-zero number, the two sides remain equal. That is the second step to solve the problem. To solve the problem, add 9.2 to both sides, that gets us 5.5x = 27.5. Now, we divide both sides by 5.5. That gets us x = 5.

1/3 equivalent first 2 fractions

andreyandreev [35.5K]

Hey there!

1/3 is equivalent to 2/6
Here is why:

1 x 2 = 2
3 x 2 = 6
You can do this by cross multiplying 1/3 and 2/6
That's how you get 2/6 as an equivalent fraction.

1/3 is also equivalent to 3/9
Here is why:
3 x 1 = 3
3 x 3 =9
You can also do this by cross multiplying 1/3 and 3/9
That's how you get 3/9 as an equivalent fraction.

There are also many other fractions that are equal to 1/3, but these are the first two.

Hope this helps you.
Have a great day!

I have a question where I need to add the mixed numbers 5 3\8 and 3 2\5 using a model and number line I have absolutely no idea

VMariaS [17]

Answer:

$8\frac{31}{40}$

Step-by-step explanation:

In representing mixed numbers on a number line, we need first to pay attention to the denominators. Here, denominators are 8 and 5, their least common multiple is 40, so, we will need to cut up space between two numbers on the number line on 40 pieces. Also, we have 5 and 3 wholes at these mixed numbers, so, our answer is going to be greater than 8.

We will cut the space between 8 and 9 on a number line on 40 pieces, and we will add $\frac{3}{8}$ and $\frac{2}{5}$ and get :
