calculate the rise and run to find the slope of the line ​

The solution of the equation 2(4-3x)+5(2x-3) = 20-5x+9 is 3.

Two or more expressions with an Equal sign is called as Equation.

The given equation is 2(4-3x)+5(2x-3) = 20-5x+9

x is the variable in the equation.

Plus and minus are the operators

Apply distributive property.

8-12x+10x-15=20-5x+9

Take the variable terms on one side and constants on other side

5x-12x+10x=20-8-15+9

3x=6

Divide both sides by 3

x=2

Hence, the solution of the equation 2(4-3x)+5(2x-3) = 20-5x+9 is 3.

Answer:

the price before the discounted price is  £120

Step-by-step explanation:

The computation of the price before the discounted price is shown below:

After giving 35% off the price is £78  that means it is 65% value

So we have to determine the 100% value

So,

= £78 × 1 ÷ 0.65

= £120

Hence, the price before the discounted price is  £120

Answer: 67.27

Step-by-step explanation:

7.1 x 7.1 for the square = 50.41

7.1 divided by 2 = 3.55

3.55 x 4.75= 16.86

Normally here you would divide by 2, but you don’t need two because there is 2 triangles that are the same

Add the 50.41 and the 16.86 and you have your answer!

Answer:

The 2 numbers = 81 and 83

Step-by-step explanation:

As, one number = x

The other, because it's an even number and consecutive = x + 2

So the larger numbef here is x + 2

And they are saying 3 times x + 2 plus x = 330

So let's solve!

3 times x + 2 = 3(x+2) = 3x + 6

So we will add it to x = (3x + 6) +(x) = 4x + 6

So they are saying the sum of them will be 330

So, 4x + 6 = 330

4x = 330 - 6

4x = 324

x = 324/4

x = 81

So x is the first number = 81

And the second is x + 2 = 81 + 2 = 83

So the 2 numbers are 81, 83

Lets check!

3 times the bigger number = 83 x 3 = 249

We will add it to 81 and we will get 330

So, 249 + 81 = 330

So the answer is right

Answer:

B. y = 11x - 7 passes through the points (2 , 15) and (3 , 26)

Step-by-step explanation:

Answer:

x = 17

Step-by-step explanation:

Since its a right triangle, you can use Pythagorean Theorem.

8² + 15² = x² (Given)

64 + 225 = x² (Simplify)

289 = x² (Add like terms)

17 = x (Square root both sides)

The number of red cells are 4 and the number of blue cells are 8. Then the correct option is C.

A ratio is a collection of ordered integers a and b represented as a/b, with b never equaling zero. A proportionate expression is one in which two items are equal.

In the grids, there are 12 square box.

Let R be the red and B be the blue.

R + B = 12   ...1

R / B = 1/2  ...2

By solving equation 1 and 2, we have

R + 2R = 12

      3R = 12

        R = 4

Then  

4 + B = 12

     B = 8

Then the correct option is C.

Answer:

The question you posted was a bit confusing for me, but I'm assuming that you want the simplified ratio of the number of white marbles to the number of green marbles.

The answer would be 8:3.

Step-by-step explanation:

There are 8 white marbles and 3 green marbles, so you get 8:3. And since 8 and 3 are relatively prime, no simplifying is needed.

The answer is 8:3.

Answer: [tex]2\dfrac14\text{ hours}[/tex]

Step-by-step explanation:

Given:  It takes a robin [tex]1\dfrac12[/tex] hours to fly 45 miles.

[tex]1\dfrac12=\dfrac32[/tex]

Speed of robin= [tex]\dfrac{distance}{time}=\dfrac{45}{\dfrac32}[/tex]

[tex]\dfrac{45}{3}\times2= 15\times2= 30\text{ miles per hour}[/tex]

A robin can fly 10 miles per hour faster than a blue jay. It

Speed of Blue jay = Speed of robin - 10 miles per hour

= 30 miles per hour - 10 miles per hour

= 20 miles per hour

Time taken to cover 45 miles = [tex]\dfrac{45}{20}=\dfrac{9}{4}=2\dfrac14\text{ hours}[/tex]

Hence, it will take [tex]2\dfrac14\text{ hours}[/tex]  by a blue jay to fly that same distance.

Answer:

B) 12

Step-by-step explanation:

(9y + 7)° + (7y - 19)° = 180° (interior angles in the same side of transversal)

(9y + 7 + 7y - 19)° = 180°

(16y - 12)° = 180°

16y - 12 = 180

16y = 180 + 12

16y = 192

y = 192/16

y = 12

Answer:

9y+7=7y-19

7+19=7y-9y

26=-2y

26/-2=-2y/-2

y=-13

Answer:

Step-by-step explanation

Given

Total number of pages to complete the packet = 6400 pages

If each ream contains 500pages, then:

Total number of reams needed = Total pages/number of pages per ream

Total number of reams needed = 6400/500

Total number of reams needed = 12.8

Hence you will need about 13 reams for all the packets

Answer:

interior angle of a heptagon = 900 degrees

900 = 4x + (3x + 60)

840 = 7x

840/7 = 120

X = 120

120 X 4 = 480

120 X 3 = 360

480 + 360 + 60 = 900

4 angles = 120 degrees each

3 angles = 140 degrees each

Answer:

The Miami Dolphins had 3 touchdowns and 3 field goals.

Step-by-step explanation:

It is given that During their last game, the Miami Dolphins scored 6 times, for a total score of 30 points. They scored 7 points for each touchdown and 3 points for each field goal.

We need to write and solve the system of equations to find the total touchdowns and field goals scored.

Let x represents the number of touchdowns.

Let y be the number of field goals.

It is given that the Miami Dolphins scored 6 times

[tex]x+y=6[/tex]

[tex]x=6-y[/tex]....(1)

They scored 7 points for each touchdown and 3 points for each field goal.

The total score is 30 points:

[tex]7x+3y=30[/tex] ...(2)

Put the value of x from equation (1) into equation (2).

[tex]7( 6-y)+3y=30[/tex]

[tex]42-7y+3y=30[/tex]

[tex]-4y=30-42[/tex]

[tex]-4y=-12[/tex]

[tex]y=3[/tex]

Put y = 3 in equation 1.

[tex]x=6-3[/tex]

[tex]x=3[/tex]

Hence, the Miami Dolphins had 3 touchdowns and 3 field goals.
