Three different recipes each make a different number of cookies and require a different amount of flour.
Recipe 1: 3 dozen cookies; 4.5 cups of flour
Recipe 2: 4 dozen cookies; 6 cups of flour
Recipe 3: 5 dozen cookies; 7.5 cups of flour
Determine if the three recipes use a proportional amount of flour.
Yes, it is proportional because the cookies increase by 1.5 dozen for every 1 cup of flour.
Yes, it is proportional because the ratios between the number of cookies and cups of flour are all equivalent.
No, it is not proportional because the number of cookies and cups of flour could not be zero at the same time.
No, it is not proportional because the ratios between the number of cookies and cups of flour are not all equivalent.
Answer:
Yes, it is proportional because the ratios between the number of cookies and cups of flour are all equivalent

Which linear equation shows a proportional relationship?
A: y equals negative 2 times x minus one fifth
B: y equals two thirds times x minus 1
C: y equals 4 times x plus 6
D: y equals three fourths times x
The linear equation shows a proportional relationship is y= 3/4 x.
What is Constant of Proportionality?If the ratio of one variable to the other is constant, then there is a proportional relationship between the two variables. If x and y are in a proportional relationship, then the ratio of y to x is the constant of proportionality. We can also express it as x is to y at times.
Given:
As, we know the constant of proportionality standard form is
y= kx
where k is constant of proportionality
So, from the given options the relation of constant of proportionality shown by
y= 3/4 x
where k = 3/4.

Write a story to represent the expression 6 divided by 3/4. Use multiplication to show the solution.
Answer: 6 divided by 3/4 is 8
Step-by-step explanation:
First when you divide 6 and 3/4. We use a dividing a fraction by a whole number. We have to make 3/4 into 4/3 to make it easier because we are trying to have a whole number. Then you multiply 6 and 4 to get 24 then you divide by 3 so you get 24/3. When you divide this, you get 8.
Once up a time there were 6 and there were 3/4. 6 was the big guy. 3/4 was the smallest in the hood. they were enemies. One day they had a fight and 6 was divided by 3/4 and became 0.5 or 1/2. now 3/4 was the big guy.

Determine the number greater than 70 but less than 85 that is divisible by both 2 and 9
20 points
The number greater than 70 but less than 85 that is divisible by both 2 and 9 will be 72.
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
The number greater than 70 but less than 85 and divisible by both 2 and 9.
The LCM of the numbers 2 and 9 will be 18. Then the number is given as,
18 x 3 = 54
18 x 4 = 72
18 x 5 = 90
The number more noteworthy than 70 yet under 85 which is distinguishable by both 2 and 9 will be 72.

5: You need to turn 8 into a fraction over 8. 8*3 = 24, so 24/3. There are 24 1/3 cups in 8.
6: She can fill more than 8 tortillas
8: This one ties back to #5, with the 24/3. You divide 24 by 2, so 12. You'll have 12 groups with 24 pieces in total. (Circle 12 groups of 2)
9: 8 / (2/3) is the same as 8*3/2 which equals 12. 12 tortillas.
10: To get a common denominator for 12/8 and 3/4, you can convert 3/4 to 6/8 [3/4 = 6/8] And since 6 is half of 12, 12/8 - 6/8 = 6/8. Mike can only fill 2 glasses

Which statement is true?
The proportional relationship is graphed correctly.
The graph does not show a proportional relationship.
Bags of Sand should be on the x-axis, and Bags of Cement should be on the y-axis.
The axes are labeled correctly with the independent and dependent variables.
Answer:
Bags of Sand should be on the x-axis and bags of Cement should be on the y-axis
Step-by-step explanation:
c = 1/3s
When we have 3 sandbags, we should have 1 cement bag (1,3)
When we have 9 sandbags, we should have 3 cement bag (3,9)
The points are plotted correctly, the labels for both axes are just switched
Answer: Bags of Sand should be on the x-axis and bags of Cement should be on the y-axis
