Bill and Amy travel the same distance from home to school of 14.4 kilometers. Amy takes 40 minutes of time to arrive to school which means she has a rate of 14.4 km /40 minutes or 6 meters/ second. Bill takes a total 60 minutes to arrive to school. Hence Bill's rate is equal to 14.4 km/60 minutes or 4 meters/ second.Amy's is 2 m/s faster than Bill's speed, then.
Sum of two numbers is 62?
Let's call the two numbers
![a](https://tex.z-dn.net/?f=a)
and
![b](https://tex.z-dn.net/?f=b)
let's find two same numbers that would add up to 62: 31.
31 + 31 = 62
since it said the difference is 8, we have to add 4 to one number and subtract 4 from another.
31 - 4 = 27
31 + 4 = 35
Therefore, the two numbers following the given rules are 27 and 35
Plotting the data to get the line of best fit, it is:
y<span> = 0.087</span>x<span> + 0.587
substitute x=2030-1980=50,
y = $4.94 is the price in 2030</span>
Answer:
<u><em>A</em></u>
Step-by-step explanation:
<u>a)</u>
<u></u>
<u></u>
<u>8(9) / 9 = 8 x 7 = 56</u>
b)
![2(3)^{2} * 3 - 4(3)](https://tex.z-dn.net/?f=2%283%29%5E%7B2%7D%20%2A%203%20-%204%283%29)
2(9) * 3 - 12
18 * 3 = 54 - 12 = 42
c)
![4(3)^{2} - 6(3) + 12](https://tex.z-dn.net/?f=4%283%29%5E%7B2%7D%20-%206%283%29%20%2B%2012)
4(9) - 18 + 12
36 - 18 = 18 + 12 = 30
d)
![7(3) + (3 * 8)](https://tex.z-dn.net/?f=7%283%29%20%2B%20%283%20%2A%208%29)
21 + 24 = 45
