Answer:

3x+10

Step-by-step explanation:

(5x+7)-(2x-3)

5x-2x=3x

7-(-3)=7+3=10

3x+10 is the answer

How to Verify:

2x-3+3x+10 MUST equal 5x+7.

Add the Variables:

2x+3x=5x

-3+10=7

5x+7

Aha! We get the original expression.

Have a marvellous day!:-)

For question 4 the Y needs to be by itself. So instead of it being x+2y>/-12 it would be y>/-6+x. You would have to subtract x on both sides and then divide 2 on both sides as well. whatever you do on one side, you have to do it on the other side. Hope this helps. After you redo all the equations, you graph them. If you need anymore help , let me know!

Paula made this model to show the sum of two mixed numbers. Write the addition equation shown by the model and solve it.
kipiarov [429]

Answer:

3\frac{2}{3} + 2\frac{2}{3} = 6\frac{1}{3}

Step-by-step explanation:

Given

See attachment for number line

Required

Determine the model

From the attachment, we can see that each partition is 1/3

The gray rectangle covers 11 partitions.

So:

Gray = 11 * \frac{1}{3}

Gray = \frac{11}{3}

Express as a mixed number

Gray = 3\frac{2}{3}

The black rectangle covers 8 partitions

So:

Black= 8 * \frac{1}{3}

Black= \frac{8}{3}

Express as a mixed number

Black= 2\frac{2}{3}

So, the model is:

Gray + Black = Total

Where Total is the point where the black rectangle stops

3\frac{2}{3} + 2\frac{2}{3} = 6\frac{1}{3}
