Answer:

2 3/8

Step-by-step explanation:

First get the LCM (Least Common Multiple) for the denominators so we can subtract them. The denominators would both be 8 because it is the lowest number that they can have to be able to subtract. (The LCM). So is 4 3/4 has a denominator of 8 it'll become:

4 3/4= 4 6/8 because if 4 turned into 8, that means it multiplied by 2. So, you need to multiply 3 by 2 as well which equals 6. This is it as a ratio:

3:4 into x:8

So 4 times 2, which means you need to do 3 times 2 as well. It equals 6.

So now that we know 4 3/4 is 4 6/8, it is time to subtract. 2 3/8 already has a denominator of 8 so we don't need to do anything with that. Subtract.

4 6/8-2 3/8= 2 3/8. 4-2=2, so the whole number is 2. 6-3= 3, so the numerator (the top number) is 3. The denominator (the bottom number) always stays the same so it is the same, which is 8.

To solve this problem you must know the following information:

1. Two lines are parallel when they are equidistant and never intersect each other, therefore, the have equal slope.

2. A transversal line is a line that cut two or more lines at different points.

3. Based on the information shown above, you have that the 30-yard line and the goal line are equidistant, they do not intersect each other and both have the same slope. Therefore, they are parallel.

4. The straight line with an angle intersect the parallel lines, therefore, it is the transversal.

The answer is: The 30-yard line and the goal line are parallel. The straight line that shows the path of the football player is the transversal line.
