Answer:

6 hours

Step-by-step explanation:

( 7h + 5h)/2 =6h

ANSWER:

It would take them about 3 hours to paint the room together.

EXPLANATION:

The least common denominator of 7 and 5 would be 35, so if we set 7x+5x equal to 35, the answer rounds up to 3. (or 2.9 if rounded to the nearest tenth.)

Answer:

160 degrees

Step-by-step explanation:

That is a straight line, meaning that the sum of a and 20 has to equal 180.

a + 20 = 180

a = 180-20

a = 160

Answer:

7x+3y2-4x

Step-by-step explanation:

The value of the difference of the polynomials are,

⇒ 7x² + 3y² - 4x

Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.

We have to given that;

The expression is,

⇒ (12x² - 11y² - 13x) - (5x² - 14y² - 9x)

Now, We can subtract the expression as;

⇒ (12x² - 11y² - 13x) - (5x² - 14y² - 9x)

⇒ 12x² - 11y² - 13x - 5x² + 14y² + 9x

⇒ 12x² - 5x² - 11y² + 14y² - 13x + 9x

⇒ 7x² + 3y² - 4x

Thus, The value of the difference of the polynomials are,

⇒ 7x² + 3y² - 4x

Answer:

Step-by-step explanation:

Answer:

Step-by-step explanation:

1) Number of white chocolate bars = x

Number of dark chocolate bars = y

Total bars = 15

x + y = 15 --------------(I)

Total cost = Php. 340

20x + 25y = 340 ----------------(II)

2)  We can use elimination method to solve this equations.

Multiply equation (I) by (-20) and then add the equations.

(I)* (-20)          -20x  -20y = - 300

(II)                    20x + 25y = 340     {Now add and x will be eliminated}

                                  5y = 40

                                    y = 40/5

y = 8

Substitute y = 8 in equation (I)

x + 8 = 15

      x = 15 - 8

x = 7

3) Number of dark chocolate bars = 8

Answer:

Step-by-step explanation:

First you have to figure out the total.  

42+23= 65

So plug it in.

23/65 = 35%

Your answer is 35%.

Hope this helped!!!!!!!!!!!!!!!!!

Answer:

35.4%

Step-by-step explanation:

Total of tiles:  42+23= 65 tiles

red tiles/ total amount of tiles

23/65= 0.3538= 35.38%

rounded to the nearest tenth= 35.4%

Answer:

-2

Step-by-step explanation:

The opposite of 2 is -2.

Answer: 12.5%

Step-by-step explanation:

108-96=12, so he grew 12 inches.

12/96=0.125,

0.125*100=12.5, 12.5%

The actual distance between the two cities is 96 miles.

The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.

We have been given that the map shows that 16 miles are represented by 0.5 inches.

Let x miles would be the actual distance between the two cities

When they are 3 inches apart on the map

According to the given situation, we can write the ratio would be as:

16 miles : 0.5 inches = x miles : 3 inches

⇒ 16/0.5 = x/3

Apply the cross-multiplication operation,

⇒ 0.5x = 48

⇒ x = 48/0.5

⇒ x = 96

Therefore, the actual distance between the two cities is 96 miles.

Answer:

t=2

Step-by-step explanation:

Literally just move all the common like terms onto one side.

6=3t

It is usually prefered to have the variables on the left and the coefficients on the right so you would flip your equation.

3t=6

Then you get t by itself by dividing by 3. Your final answer should be 2.

Answer:

x = -6, 2

Step-by-step explanation:

A zero is the x-value of a point on the x-axis that the graph intersects. Knowing this, we can set the function itself to 0 to find the zeros.

1) Set the function to 0.

[tex]x^2+4x-12 = 0[/tex]

2) Factor out the polynomial. Ask yourself, what are two numbers that have a product of -12 and add up to 4? (In this case, it's 6 and -2.)

[tex]x^2+4x-12 = 0\\(x+6)(x-2) = 0[/tex]

3) Look at the answer from the last step. What do the x's have to equal in order for equation to equal 0? They have to be -6 and 2. Therefore, those are the zeros.

Answer:

24y^3/x^5

Step-by-step explanation:

Since 6x and 4x are not in a parentheses, they are not being powered by anything. Therefore, those stay on the numerator side.

Anything to the power of something times another to the power of something is always added together. Since -1 + (-4) is -5, x would end up having a power of -5, which would just make it go on the denominator side with just a power of 5.

Same rule with y follows. This would make it 5+ (-2) = 3. Since this is a positive power, it stays at the numerator side.

Answer:

the answer is c because it is the only one with the y intercept

Please check the explanation below.

Step-by-step explanation:

Note: As you forgot to mention the graphs of a linear function. But, let me clear your concept with an example of a linear function.

We know that linear function is of the form

y = mx+b

where

We know that the graph of a linear function is a straight line because the highest power of the exponent of the x variable is 1.

Thus, y = mx+b represents a straight line.

For example,

Let the linear function

y = 2x+3

comparing with the linear function of the form y = mx+b

As the highest power of the exponent of a variable is 1, therefore y = 2x+3 represents a straight line.

The graph of the linear function y = 2x+3 is also attached below.

The volume of a rectangular prism is defined as the space occupied within a rectangular prism. A rectangular prism is a polyhedron that has two pairs of congruent and parallel bases. It has 6 faces (all are rectangular),12 sides, and 8 vertices. As the rectangular prism is a three-dimensional shape (3D shape), the unit that is used to express the volume of the rectangular prism is cm3, m3 and so on.

Given here: The dimensions as 3,3,3

Thus the volume is = 3³

                                =27
