Answer:
4/5
Step-by-step explanation:
x2-x1/y2-y1
-2-2=-4
-1-4=-5
-4/-5
Simplify
4/5
The slope is 4/5
Yes they are equivalent because their ratio is 9
81/9= 9
63/7=9
Answer:
50/50
Step-by-step explanation:
You could use many methods to find the answer to this problem, but I am going to use the most efficient one I know.
18f+15(4f)=156
F is for fins. We should now solve the equation.
18f+60f=156
78f=156
156÷78=2
So fins cost 2 dollars. Now, we know snorkels cost four times the amount of fins. Four times 2 is eight. So the snorkels cost $8 to rent. Let's check our math.
15(8) + 18(2)
120+36=156
So it cost $8 to rent a snorkel.
It is most likely equal to two soccer fields
