Step-by-step explanation:
-7-30
=-37
You are adding the negatives therefore, you will get a larger number of negatives.
you would have to plug the numbers given.
“A” would now be (-7) “B” would now be (30) = (-7)-30 = -37
reason it equals a negative is because a positive & a negative = a negative

-7.5
Step-by-step explanation:
Whole numbers are natural numbers from 0 to infinity. This does not include decimals or fractions. For example, these numbers are 0, 1, 2, 3, 4...
Integers are whole numbers, but they include negative numbers. So, from negative infinity to positive infinity. This does not include decimals or fractions. For example, these numbers are ... -3, -2, -1, 0, 1, 2, 3 ...
A rational number is any number that can be expressed as a fraction. So, this includes -7.5, as -7.5 can be expressed as -[tex]\frac{15}{2}[/tex].
Therefore the answer is -7.5.

10x²+6x
Answers
Answer:
2x(5x + 3)
Step-by-step explanation:
Factor out common factors. Note that both terms have x inside it. Therefore, you will factor out one x from each term.
Note the factors of both 10 & 6:
10: 1 , 2 , 5, 10
6: 1 , 2 , 3, 6
Note that the greatest factor shared is 2. Divide 2 and x out from both terms:
(10x² + 6x)/2x = 5x + 3
2x(5x + 3) is your answer.

15 - 5k ≥ 0
solve the inequality
Answers
15 + 15 will cancel out
15 + 0 = 15
After you are left with just 5k and 15
Divided 5 on both sides of the inequality
5k/5 ( this will cancel out)
15/5 = 3
Bring down the k & inequality sign
Final Answer :
The solution is, the value of the inequality is, 3 ≥ k.
What is inequality?An inequality is a relation which makes a non-equal comparison between two numbers or mathematical expressions.
here, we have,
given that,
15 - 5k ≥ 0
now, we get,
Start by adding 15 to both sides
15 + 15 will cancel out
15 + 0 = 15
After you are left with just 5k and 15
Divided 5 on both sides of the inequality
5k/5 ( this will cancel out)
15/5 = 3
Bring down the k & inequality sign
3 - k ≥ 0
adding k on both side,
3 ≥ k
Final Answer : 3 ≥ k

Step-by-step explanation:
3100
The amount of money in the account that he has after 4 years will be $3100.
What is simple interest?Simple interest is the concept that is used in many companies such as banking, finance, automobile, and so on.
A = P + (PRT)/100
Where P is the principal, R is the rate of interest, and T is the time.
You make a $2,500 initial deposit into an account that pays 6% simple interest per year.
Then the amount of money in the account that he has after 4 years will be given as,
A = 2500 + (2500 x 6 x 4)/100
A = 2500 + 600
A = $3100
The amount of money in the account that he has after 4 years will be $3100.

Step-by-step explanation:
A pet store has three fish tanks, each holding a different volume of water and a different number of fish.
Order the tanks by volume per fish from least to greatest.
Tank A holds 40 L and 5 fish.
= 40L/5 fishes
= 8 volume per fish
Tank B holds 100 L and 12 fish
= 100L/12 fishes
= 8.3333333333 volume per fish
Tank C holds 180 L and 23 fish.
= 180L /23 fish
= 7.8260869565 volume per fish
The tanks by volume per fish from least to greatest

The length of a rectangle is twice the width. The area of the rectangle is 80 square units. Notice that you can divide the rectangle into two squares with equal area. How can you estimate the side length of each square? Estimate the length and width of the rectangle.
Answers
Answer:
Width of the rectangle = 6.325 units
Length of the rectangle = 12.65 units
Side length of the square the 6.325 units.
Step-by-step explanation:
The length of a rectangle is twice the width. The area of the rectangle is 80 square units.
The area of the rectangle = Length × Width
Length = 2W
80 square units = 2W × W
80 = 2W²
W² = 80/2
W² = 40
W = √40
Width of the rectangle = 6.3245553203 units
Approximately = 6.325 units
Length = 2 × Width
= 2 × 6.325
= 12.65 units
• Notice that you can divide the rectangle into two squares with equal area. How can you estimate the side length of each square?
We you divide a rectangle into 2 squares,
The length is divided into two.
Hence, the length of the rectangle = 12.65 units
12.65 units ÷ 2 = 6.325 units.
Hence, the side length of the square the 6.325 units.
Elsa is staining the wooden floor of a court. The court is in the shape of a rectangle. Its length is 43 feet and its width is 36 feet. Suppose each can of wood stain covers 172 square feet. How many cans will she need to cover the court?

Ellie bought cookies and cupcakes from Publix for $102.44. If she spent $36.44 on cookies and the cupcakes are $11 per box, which equation represents this situation?
A)11x - 36.44 = 102.44
B)102.44x + 11 = 36.44
C)11x + 36,44 = 10244
D)102.44 + 36.44x = 11
Answers
Answer:
C
Step-by-step explanation:
She spent $102.44 in total.
She spent $36.44 on cookies.
And $11 per box of cupcakes.
This means that she knows the exact amount she spent on cookies and in total so now to find out how much she spent on cupcakes, she subtracts $36.44 from $102.44($66) and then divides 66 by 11(6). So if you needed the problem solved x=6.
