Step-by-step explanation:
Thanks Okay
Answer:
The answer is 0.
Step-by-step explanation:
solve 9+5=14
14/7=2
2-2=0
solve the pther side
25-20=5
4*5=20
0*20=0
That it is 4,6090 because when u divide that ,400 by 2,400 u will get 4,000

The answer is D
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
