Answer: C. 966

Step-by-step explanation: First find the ft. of the entire area, the deck, and pool. Then get the area of the pool

Entire area: (35+7+7) * (20+7+7)= 1666

Pool: 35*20=700

Then subtract the ft. of the entire area by the pool

1666-700= 966

Answer:

Whole numbers are positive numbers (this includes 0) that do not have decimals or fractions to them.

Example:

1, 2, 3, 4, 5,etc are all whole numbers, because they are positive and do not have decimals or fractions

1.25 would not be a whole number, because although it is positive, it has a decimal.

Answer:

x>-33/8

Step-by-step explanation:

9+8x>-24

1) Subtract 9 from both sides:

8x>-33

2) Divide both sides by 8:

x>-33/8

The algebraic representation of the problem is 9 + 8x > -24. After isolating 'x', the solution to the inequality is x > -4.125, which means any number greater than -4.125 satisfies the equation.

The problem presented is a linear inequality, a topic of mathematics. The sentence 'Nine increased by the product of a number and 8 is greater than -24' can be represented algebraically as 9+8x > -24, where 'x' is the number in question.

To solve it, as we aim to find the value for 'x', you first isolate 'x' on one side of the inequality. Start by subtracting 9 from both sides to get 8x > -24 - 9, which results in 8x > -33. Then, you divide both sides by 8 to solve for 'x'. As a result, x > -33/8, or x > -4.125.

This means that any number greater than -4.125 will satisfy the equation 'Nine increased by the product of a number and 8 is greater than -24'. So, the solution to this inequality is x > -4.125.

Answer:

120 mins

or

2hrs

Step-by-step explanation:60 min=1 hr

60 min/5=12 min

12(4)=48 min

24 min=1/5 of room

24(5)=120 min

120 min=2 hrs

It would take 2 hours to paint one room.

Ratio basically compares quantities, that means it shows the value of one quantity with respect to the other quantity.

If a and b are two values, their ratio will be a:b,

Given that,

Time taken to paint 2/5 of the room = 4/5 hour

To find the time taken to paint one room,

Use ratio property,

2/5 room takes = 4/5 hour

1 room takes = 4/5 x 5/2 hours

                      = 4 / 2 hours

                      = 2 hours.

Given, (4x+6)/2=(3x-15)/3

Apply cross multiplication method

3(4x+6)=2(3x-15)

12x+18=6x-30

12x-6x=-30-18

6x=-48

20%

Step-by-step explanation:

15= 100%

100% divided by 5 is 20%

proportion: 1/5

Mimi has 15 cousins, and after subtracting the 3 who do not live in Texas, 12 of her cousins live there. By setting up a proportion, we calculate that 80% of Mimi's cousins live in Texas.

Mimi has 15 cousins, and all but 3 live in Texas. To find the percentage of her cousins that live in Texas, we first need to calculate the number of cousins who live in Texas. We do this by subtracting the 3 that do not live in Texas from the total number of cousins, which is 15.

Number of cousins living in Texas = Total cousins - Cousins not living in Texas
Number of cousins living in Texas = 15 - 3 = 12

Next, we set up a proportion to find the percentage. The proportion is based on the number of cousins in Texas over the total number of cousins:

Proportion = (Number of cousins in Texas / Total number of cousins) ×100%
Percentage = (12 / 15)× 100%
Percentage = 0.80 × 100%
Percentage = 80%

Therefore, 80% of Mimi's cousins live in Texas.

1. Simplifying

9x + 2y = 30

Solving

9x + 2y = 30

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-2y' to each side of the equation.

9x + 2y + -2y = 30 + -2y

Combine like terms: 2y + -2y = 0

9x + 0 = 30 + -2y

9x = 30 + -2y

Divide each side by '9'.

x = 3.333333333 + -0.2222222222y

Simplifying

x = 3.333333333 + -0.2222222222y

3. Reduce expression by...cancelling your common factors...

Cancel...2 from 2y/2

6x+4y=12

Divide y by 1...

y=30/2+-9x/2

6x+4y=12

4.Simplify each term...

-Divide thirty by two.

y=15+-9x/2

6x+4y=12

-Move your negative in the front of your fraction.

y=15 - 9x/2

6x+4y=12

5.  Subtract 6x from both sides of your equation...

y=15 - 9x/2

4y=12-6x

6. Divide each term by four...divide terms in 4y=12-6x by four...

y=15 - 9x/2

4y/4=12/4+-6x/4

-Reduce expression by cancelling common factors in 4y/4...

Divide y by one...

y=15 - 9x/2

y=12/4+-6x/2

7. Simplify each term...Divide twelve by four...

y=15 - 9x/2

y=3+-6x/4

-Reduce expression by cancelling all common factors...

Your factor is 2 our of -6x...

y=15 - 9x/2

y=3+2(-3x)/4

-Cancel the common factors.. two out of four...

y=15 - 9x/2

y=3+2(-3x)/2(2)

-Cancel common factors again...

y=15 - 9x/2

y=3+-3x/2

8. Move your negative over to the front of your fraction...

y= 15 - 9x/2

y=3 - 3x/2

You get... (4,-3)

HEY LUVS

Final answer:

To simplify an algebraic equation, combine like terms, reduce fractions, and cancel factors; multiply or divide both sides by the same number if needed, and check your work by substituting values back into the original equation.

Explanation:

Simplifying Algebraic Equations

To simplify an algebraic equation, you need to eliminate terms wherever possible. This process may involve combining like terms, reducing fractions, and canceling out factors. Multiplication or division by the same number on both sides of the equation does not change the equation's equality, so apply these operations carefully to all terms. Often, you'll want to collect constants inside the parentheses to consolidate them into a single value, making the equation simpler. After simplifying, it's important to check your answer to ensure that it is reasonable, which may involve plugging the solution back into the original equation or assessing the steps you've taken to make sure no errors were made.

Let's consider an example:

Simplify the equation by dividing both sides by a common factor, if applicable.

Collect like terms together and simplify further.

Check the simplified equation by substituting numbers to see if both sides remain equal or by ensuring logical algebraic steps were taken.

Remember, solving for an unknown variable requires doing the same operation on both sides of the equation, thereby maintaining balance. Systematic simplification and attentive checking are your keys to mastering algebraic equations.

Answer:8

Step-by-step explanation: trust me

The relationship between y and x, given that g is the midpoint of FH is y = (1/3)x + (1/3).

If g is the midpoint of FH, it means that FH is divided into two equal segments, FG and GH, such that FG = GH.

Given that FH = 6y - 2, set up an equation to represent this:

FH = FG + GH

Substituting the values we know:

6y - 2 = FG + GH

Since FG = GH then

6y - 2 = x + x

Now, combine like terms:

6y - 2 = 2x

To find the value of y, isolate it on one side of the equation:

6y = 2x + 2

Now, divide both sides by 6 to solve for y:

y = (2x + 2) / 6

y = (2/6)x + (2/6)

y = (1/3)x + (1/3)

So, y is equal to (1/3)x + (1/3).
