Answer:
y = 3x - 5
Step-by-step explanation:
The equation of a line parallel to y=3x+6 has exactly the same form but a different constant on the right: y=3x+C
To find C, take the coordinates of the given point and substitute them into y=3x+C:
7 = 3(4) + C, or
7 = 12 + C, and so C = -5
The desired equation is y = 3x - 5
Answer: 15 crocodriles
Step-by-step explanation:
We know that the ratio is 4:3
This means that for each 4 hippos, we have 3 cocodriles.
We know that there are 20 hippos.
How many groups of 4 hippos we have?
n = 20/4 = 5
So we have 5 groups of 4 hippos, this means that we also have 5 groups of 3 crocodiles, then we have:
3*5 = 15 crocodiles
Answer:
Step-by-step explanation:
1 hour = 3600 seconds
Distance traveled in 90 seconds = 5 feet
Distance traveled in 1 second = 5/90
Distance traveled in 3600 seconds = 5*3600 / 90
= 5 * 40 = 200 feet
