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.

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.

At Frameworks Hardware Store's annual start-of-summer sale, every drill set in the shop gets marked down. Arianna purchased 2 drill sets during the sale: one for herself and one to give her grandpa on Father's Day. Each drill set cost $25 less than its full price. She paid a total of $86.
write an equation you can use to find f, the cost of each drill set at full price?
Assuming f to be the cost of the drill set at full price,
The equation which will represent this is
2( f- 25) = 862(f−25)=86
Solve for f to get
2f - 50 = 862f−50=86
2f = 1362f=136
f = 68f=68
The cost of the drill set at full price is $68.

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:

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.

The equation c equals one third times s represents the proportional relationship between the number of bags of cement (c) and the number of bags of sand (s) required to make concrete. A graph of this relationship is shown.
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

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.

Dena wants to make a birdhouse with the leftover wood. she needs 105 3/5 centimeters of wood for the birdhouse. write and evaluate an expression to determine how much how much more wood will be needed. PLEASE HELPPP
Answer:
Step-by-step explanation:
hi sorry if this is wrong but the answer is Dena wants to make a birdhouse with the leftover wood. but She needs 105 3/5 of wood
Dena needs 1.15 centimeters more of wood is needed to make the birdhouse.
What is an expression?An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division.
A. To find the total length of wood left over, we need to add the lengths of all 5 pieces of wood.
We can represent each piece of wood with a fraction and then add all the fractions.
The total length of wood can be represented as:
12.7 + 26 3/10 + 15 4/5 + 21 1/4 + 19.2 = (12.7 + 26 + 15 + 21 + 19.2) + (3/10 + 4/5 + 1/4)
To simplify the expression, we can convert the mixed numbers (26 3/10 and 21 1/4) to improper fractions and convert the fractional part of decimals (3/10 and 4/5) to decimals:
12.7 + 26 3/10 = 12.7 + 26.3
15 4/5 = 15 + 0.8
21 1/4 = 21 + 0.25
3/10 = 0.3
4/5 = 0.8
So, the expression becomes:
12.7 + 26.3 + 15 + 0.8 + 21 + 0.25 + 19.2 = (12.7 + 26.3 + 15 + 0.8 + 21 + 0.25 + 19.2) + 0.3 + 0.8 = 104.45
Therefore, the total length of wood left over is 104.45 centimeters.
B. To determine how much more wood will be needed for the birdhouse, we can subtract the total length of wood left over from the required length:
105 3/5 - 104.45 = (105 + 0.6) - 104.45 = 105.6 - 104.45 = 1.15
Therefore, 1.15 centimeters more of wood is needed to make the birdhouse.
