Answers

part a : a coefficient is 10.5

a variable is c 

a constant is 50 

part b : $618.50

part c : the coefficient would change because instead of it being 10.5 in front of the variable "h" it is now 11.25 in front of the variable.


Part A. h and c are variables 10.15 and 15 are coefficients 50 is the constant
Part B.Put h=37 and c=12
Part C.$11.25 instead of 10.15 i.e. eq. becomes 11.25h + 15c + 50

The sum of a certain number and 8 is 23. What is the number?
equation:


n =

Answers

So mathematically, it's n + 8 = 23

Just subtract both sides by 8 and you will get n = 15
n + 8 = 23
n = 15 (subtract 8 from both sides).

There you go.

Find the greatest number you can add to 4315 without having to regroup

Answers

  4315
+5684
 9999    So 5684 is the greatest number you can write.

Final answer:

The greatest number that can be added to 4315 without having to regroup is 5644. When added together, the sum doesn't result in a carryover to the next place value.

Explanation:

In Mathematics, particularly arithmetic, regrouping is the process of making groups of tens when adding or subtracting two numbers. When the question asks for the greatest number that can be added to 4315 without having to regroup, we are essentially looking for a number that when added to 4315 doesn't result in a carryover to the next place value.

Considering the number 4315, you would notice that the units digit is 5, the tens digit is 1, the hundreds digit is 3, and the thousands digit is 4. This means for each position we can add a number up to 9 without needing to regroup. Hence, the greatest number you can add to 4315 without needing to regroup would be 5644 (which gives 9 in the units place, 1+5=6 in the tens place, 3+4=7 in the hundreds place, and 4+4=8 in the thousands place).

What is the solution of the equation
7x + 3 = 2x + 13

Answers

Answer:

Step-by-step explanation:

7x + 3 = 2x + 13

5x + 3 = 13

5x = 10

x = 2

Answer:

x = 2

Step-by-step explanation:

given

7x + 3 = 2x + 13 ( subtract 2x from both sides )

7x - 2x + 3 = 2x - 2x + 13 ( simplify both sides )

5x + 3 = 13 ( subtract 3 from both sides )

5x + 3 - 3 = 13 - 3 ( simplify both sides )

5x = 10 ( divide both sides by 5 )

(5)/(5) x = (10)/(5) , that is

x = 2

Tabitha wants to hang a painting in a gallery. The painting and frame must have an area of 58 square feet. The painting is 7 feet wide by 8 feet long. Which quadratic equation can be used to determine the thickness of the frame, x?

(See picture attached below)

Answer Choices:
A. x2 + 15x − 2 = 0
B. x2 + 15x + 58 = 0
C. 4x2 + 30x − 2 = 0
D. 4x2 + 30x + 58 = 0

Answers

If the total area of the painting and the frame is 58 sq ft, we have the equation:
(8 + 2x)(7 + 2x) = 58

Expanding the equation,
56 + 30x + 4x^2 = 58

Combining like terms and arranging the equation, we have:
4x^2 + 30x - 2 = 0

Therefore, the answer is
C. 4x2 + 30x − 2 = 0
