Which ordered pair has an x-coordinate value of 7? (4, 7) (3, 4) (3, 10)(3, 10) (7, 10)

Okay -

An ordered pair is in the form of (x, y). The first value is the x-coordinate, and the second is the y-coordinate. 

So, we simply have to look at all of the ordered pairs and see which one has the first value equal to 7. 

In this case, it is (7, 10)! =)

Answer/Step-by-step explanation:

The circle by your left:

(4x + 3y) + (2x - y)

Distribute +1

4x + 3y + 2x - y

Add like terms together

6x + 2y

The rectangle by at the bottom right:

(4x + 5y) - (x + 4y)

Distribute -1

4x + 5y - x - 4y

Group like terms

4x - x + 5y - 4y

3x + y

The circle at the bottom middle:

(2x - y) + (3x + y)

Distribute +1

2x - y + 3x + y

Group like terms

2x + 3x - y + y

5x
