Constant of proportionality is 4
equation: x/y = 4
explanation:
let's take 20 and 5 for example, if you divide 20 by 5, you will 4 of course. that's the proportionality for the first one. if you continue to divide x value by y value you will get 4. for the last two you would divide 28 by 4 and multiply 8 by 4.
30 degrees is what the answer is because it says it in the question
Answer:
60 mph
Step-by-step explanation:
Time:miles
4:240
1:x
To get x divide 240 by 4 because that's what we divided 4 by to get 1
The rate is 60
select all times with the rate of 60 mph
Yes because all sides would be equal to 5 which would give you 5*4 = 20 units.
4y ≥ 3x + 2
Plugging in the values in the options, then the required values are when x = 6 and y = 5, then
4(5) ≥ 3(6) + 2
20 ≥ 18 + 2
20 ≥ 20
