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

The number greater than 70 but less than 85 that is divisible by both 2 and 9 will be 72.

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.

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.

Answer:

b) -9.2y - 49.6

Step-by-step explanation:

Given expression,

→ 4(-2.3y - 12.4)

Simplifying the expression,

→ 4(-2.3y - 12.4)

→ (4 × -2.3y) - (4 × 12.4)

→ -9.2y - 49.6

Hence, option (b) is correct.

The linear equation shows a proportional relationship is y= 3/4 x.

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.
