C. 15 units
D. 16 units

2nd question;
Mary wants to find the horizontal distance between coordinate points (9,4) and (3,4) what can be so to find that distance?

A. Add the x-coordinates
B. Add the y-coordinates
C. Subtract the x-coordinates
D. Subtract the y-coordinates

Explanation:

For the first question, look at the y values. They are 3 and 12. To find the length between those values, subtract and you'll get 9 units.

For the second question, you would subtract the x-coordinates.

* For both of these questions, make sure you know your x and y axes. The    y-axis is always vertical and the x-axis is always horizontal.

Answers:

1. 9 units

2. subtract the x-coordinates

yes

step-by-step explanation:

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls
