Brittany went grocery shopping , she spent 4/7 of her money on fresh foods. she spent 2/3 of the remainder of her money on frozen foods. if she spent 22$ on frozen foods. how much money did she spend on fresh foods?
Answers
Answer:
$44
Step-by-step explanation:
Let the total amount of money be represented by Y
Amount spent on fresh food =
[tex] \frac{4}{7} \times y[/tex]
Remainder =
[tex]y - \frac{4}{7}y = \frac{3}{7} y[/tex]
Amount spent on frozen foods = two-thirds of remainder = $22
[tex] = \frac{2}{3} \times \frac{3}{7} y = \frac{2}{7} y[/tex]
[tex]\frac{2}{7} y = 22 \\ y = 22 \times \frac{7}{2} \\ y = 77[/tex]
The total amount for grocery shopping is $77
Therefore, Brittany spent $44 on fresh foods
[tex] = \frac{4}{7} \times 77 \\ = 4 \times 11 \\ = 44[/tex]

Cheryl, Rita and four of their friends go to a movie and share a 48-ounce bag of popcorn equally and three 48 inch licorice laces equally write a ratio comparing the number of ounces of popcorn to the number of friends. then write a unit rate comparing the lenght of licorice lace for each person.
Answers
Answer:
Ratio of 48:5 and 28.8 inches of licorice per friend
Step-by-step explanation:
Ratio: Rita AND 4 of her friends go to the movie, meaning there would be 5 people. All 5 of them decide to share a 48 0unce bag of popcorn. The number problem is asking you to create a ratio comparing the number of ounces of popcorn (48) to the number of friends (5). Therefore, your ratio would be 48:5
Unit rate: Once again, there are 5 people there. Those 5 friends would like to share three 48inch long peices of licorice. The question is asking you to decide how many inches of licorice each friend gets. The first step would be to see how many inches in total we have by multiplying 48*3. That is 144 inches of licorice. The next step would be to divide the number of inches by the number of friends. That would be 144/5 and give you 28.8. The last step is to write out your unit rate. 28.8 inches of licorice per friend.
Hope that helped!

What is the equation of the line?
Answers
Answer:
y = 1/2 - 3/2
Step-by-step explanation:
All we need to do is find the y-intercept of the line using the formula for slope intercept form [ y = mx + b ].
-3 = 1/2(-3) + b
-3 = -1.5 + b
-1.5 = b
We can put all the information we know/solved for into the formula.
y = 1/2 - 1.5
Best of Luck!
Answer:
The equation of the line is y = 1/2x - 3/2
Step-by-step explanation:
Plug in point (-3, 3) with slope 1/2 into y = mx + b
-3 = 1/2(-3) + b
-3 = -3/2 + b
+3/2 +3/2
-------------------
-3/2 = b
hence, y = 1/2x - 3/2

Mrs. Balbas makes a batch of cookies for her math class. Aaron takes 1/6 of the cookies and runs out the door. Matthew then takes 1/5 of the cookies that are left. Paige takes 1/4 of what remains after Matthew leaves. Koji takes 1/3of what remains after Paige, and then Dylan grabs half of the remaining cookies after Koji. Gavin then swoops in and grabs the last remaining 6 cookies. The rest of the class gets nothing and begins to collectively cry. How many cookies were in the batch, to begin with?
Answers
Answer:
36
Step-by-step explanation:
After dylan took half of the cookies and 6 were left there were
12 before he took any
Than If Koji took a 3rd when 12 were left there were 18
Than if Paige took a 1/4 of what was left when there were 18 there were 24
This same pattern is the same for the next 2
24+6 = 30 and than 30+6 = 36
TLDR;
remove 6 per person meaning there were 36 to begin
Mrs. Balbas makes a batch of cookies for her math class. Aaron takes 1/6 of the cookies and runs out the door. Matthew then takes 1/5 of the cookies that are left. Paige takes 1/4 of what remains after Matthew leaves. Koji takes 1/3of what remains after Paige, and then Dylan grabs half of the remaining cookies after Koji. Gavin then swoops in and grabs the last remaining 6 cookies then the batch initially had 432 cookies.
Mrs. Balbas baked a batch of cookies for her math class.
1. Aaron takes 1/6 of the cookies:
If "C" represents the initial number of cookies, Aaron takes (1/6)C cookies, leaving (5/6)C cookies.
2. Matthew takes 1/5 of the remaining cookies:
Matthew takes (1/5)(5/6)C = (1/6)C cookies, leaving (5/6)C - (1/6)C = (2/3)C cookies.
3. Paige takes 1/4 of the remaining cookies:
Paige takes (1/4)(2/3)C = (1/6)C cookies, leaving (2/3)C - (1/6)C = (1/2)C cookies.
4. Koji takes 1/3 of the remaining cookies:
Koji takes (1/3)(1/2)C = (1/6)C cookies, leaving (1/2)C - (1/6)C = (1/3)C cookies.
5. Dylan takes half of the remaining cookies:
Dylan takes (1/2)(1/3)C = (1/6)C cookies, leaving (1/3)C - (1/6)C = (1/6)C cookies.
6. Gavin takes the last 6 cookies:
The remaining (1/6)C - 6 cookies are taken by Gavin.
7. The rest of the class gets nothing, leaving 0 cookies.
Now, let's add up the amounts taken by each student:
- Aaron: (1/6)C
- Matthew: (1/6)C
- Paige: (1/6)C
- Koji: (1/6)C
- Dylan: (1/6)C
- Gavin: 6 cookies
Adding all these together, we get:
(1/6)C + (1/6)C + (1/6)C + (1/6)C + (1/6)C + 6 = (5/6)C + 6
Since the remaining cookies are accounted for,
we know that (5/6)C + 6 = 0, which gives us C = 432.
Therefore, the initial batch had 432 cookies.

the sum of three consecutive odd integers. what are the three integers
Answers
Answer:
I dont know
Step-by-step explanation:
Answer:
Complete step-by-step answer:
Sum of 3 consecutive odd numbers is equal to 51.
Let the odd number be ‘x’. Then the next consecutive odd number becomes ‘x + 2’ and the next term becomes x + 2 + 2 = ‘x + 4’.
Now the sum of these three odd consecutive terms = x + x + 2 + x + 4 = 3x + 6.
According to the given, 3x + 6 = 51.
⟹3x = 51 – 6
⟹x =453=15.
Hence, the numbers are 15, 17 and 19.
Note: In order to solve this type of questions the key is to consider a variable to be odd and compute the sum of three consecutive odd numbers in terms of this variable. Then by solving for this variable we can determine the numbers. Any odd number added with 2 gives an odd number itself.
