So,
#1:

Convert to like improper fractions.

Add.

So, one solution could be

.
Another solution could by 9. There is also 10, 11, 12, etc., and all numbers in between.
#2:

Convert into improper fraction form.

Multiply.

Cross-cancel, and we have our final result.

k < 96
96 is not a solution.
95 is a solution.
So is 94, 93, 92, etc, and all numbers in between.
Answer:
x=1.5
Step-by-step explanation:
- 5=10(5x-7)
- 0.5=5x-7
- 7.5=5x
- x=1.5
Yes. Use pythagorean theorem to find that: 9^2 + 12^2 =225 and 15^2 =225.
slope=y2-y1/x2-x1
5-2/3-2
denominator will show 3-2
