It is divided by two each time. They will sell 10 slices of pizza on week 6.
Step-by-step explanation:
Answer:
2, 10, 6
Step-by-step explanation:
160 is half of 320, so that's a divide by 2. 80 is half of 160, so that's also divide by 2. This is the first answer.
Now, we want to know how many weeks until 10 slices are sold in the week. That's the second answer.
To get the third answer, we'll just go down from 80. 80 divided by 2 is 40, so in the 4th week, the cafeteria would sell 40 slices. Divide 40 by 2 and we'll get 20. So, in the fifth week, the cafeteria would sell 20 slices.
20 divided by 2 is 10. That's the sixth week. So, in the sixth week, the cafeteria sells 10 slices. That's the third answer.

Cecile packages snack mix at a health food store.
She uses 13 of her supply of sunflower seeds to make a salted snack mix and 29 of her supply to make an unsalted snack mix. If Cecile uses 10 pounds of sunflower seeds, how many pounds of seeds are in her supply?
18 pounds
23 pounds
30 pounds
40 pounds
Answers
Answer:
Her supply has 18 pounds
Please give branliest :)
Explanation:
Assume that the number of pounds in her supply is x.
We are given that:
She uses 1/3 x in salted mix and 2/9 x in unsalted mix.
This means that:
Total amount used = 1/3 x + 2/9 x = 5/9 x of her supply
Now, we are also given that:
She used 10 pounds of her supply.
This means that:
5/9 x = 10
5x = 9*10 = 90
x = 18 pounds

What is the surface area of the following triangular prism?
screenshot below :)
a. 24 yd 2
b. 96 yd 2
c. 50 yd 2
d. 90 yd 2
Answers
Answer:
The answer is 96 yd 2
Step-by-step explanation:
First for the triangle bases, you multiply the 3 by 4 and divide by 2 to get one base which is 6, then double it to get the other base on the top to get a total of 12. Then you just find the area of the other sides of the prism by multiplying the lengths and widths.
5x7=35
4x7=28
3x7=21
then you add all of the total values together:
35+28+21+12=96

Solve the following system of equations.
2x+y=3
x=2y+1
Make sure there are NO SPACES in your answer. Include a comma in your answer.
ANSWER: {( )}
Answers
now we have
2x = -y + 3
divide both sides by 3
x= -y/2 + 3/2
the other x equals 2y +1, set these equal to eachother
2y + 1 = -y/2 + 3/2
add y/2 to both sides
2.5y + 1 = 3/2
subtract 1 from both sides
2.5y = 0.5
divide both sides by 2.5
y=0.2
plug in 0.2 for y in an original equation
x = 2(0.2) + 1
solve
x = 1.4
ANSWER:
x= 1.4
y= 0.2
