Hi,
Let the
Youngest brothers age = x+2
Middle brothers age = x+4
Oldest brothers age = x+6
So,
Youngest brothers age = x+2 = 28+2 = 30 years of age
Middle brothers age = x+4 = 28+4 = 32 years of age
Oldest brothers age = x+6 = 28+6 = 34 years of age
Have a great day!
Answer:
If your talking about the containers, then you would need 80
containers, hope this helps.
Step-by-step explanation:
Acceleration is simplified by assuming it is the constant -g
a=-g we integrate this with respect to time to get v...
v=-gt+C where C is the initial velocity in this case 14ft/s so
v=-gt+14 integrate again to get the height function
h=(-gt^2)/2 +14t +C we are not given an initial height so C is 0
h(t)=14t-gt^2/2 letting g=32 and neatening up a bit...
h(t)=14t-16t^2

Step-by-step explanation:
Answer:
Part 9) The number of items on Emily's grocery list is 5 and the number of items on Bobby's grocery list is 13
Part 10) The height of the taller bookshelf is 4 feet and the height of the shorter bookshelf is 1 foot
Step-by-step explanation:
Part 9)
Let
x ----> number of items on Emily's grocery list
x ----> number of items on Bobby's grocery list
we know that
----> equation A
----> equation B
Solve by substitution
Substitute equation A in equation B
![x=(2x+3)-8](https://tex.z-dn.net/?f=x%3D%282x%2B3%29-8)
solve for x
![x=2x-5](https://tex.z-dn.net/?f=x%3D2x-5)
![2x-x=5](https://tex.z-dn.net/?f=2x-x%3D5)
![x=5](https://tex.z-dn.net/?f=x%3D5)
Find the value of y
![y=2(5)+3=13](https://tex.z-dn.net/?f=y%3D2%285%29%2B3%3D13)
therefore
The number of items on Emily's grocery list is 5 and the number of items on Bobby's grocery list is 13
Part 10)
Let
x ----> the height of the taller bookshelf in feet
y ----> the height of the shorter bookshelf in feet
we have
----> equation A
Remember that
![1\ ft=12\ in](https://tex.z-dn.net/?f=1%5C%20ft%3D12%5C%20in)
To convert inches to feet divide by 12
so
![60\ in=60/12=5\ ft](https://tex.z-dn.net/?f=60%5C%20in%3D60%2F12%3D5%5C%20ft)
----> equation B
Solve the system by substitution
substitute equation A in equation B
solve for y
Find the value of x
![x=5(1)-1=4\ ft](https://tex.z-dn.net/?f=x%3D5%281%29-1%3D4%5C%20ft)
therefore
The height of the taller bookshelf is 4 feet and the height of the shorter bookshelf is 1 foot
