Answer:

x=4

Plz, mark brainiest! ^.^

Answer:

x = 4

Step-by-step explanation:

Use the distributive property to distribute the -3 amongst the 2x and the -3 in the parenthesis. Once distributed you should have -6x + 9 = -5x + 5. Next, you want to get all like terms on the same side, and to do that you must swap the +9 and the -5x. When you swap these, you must 'flip' the sign and change 9 to -9 and -5x to 5x. Now the equation should look like this: -6x + 5x = -9 + 5.

Now just solve. After solving, it should look like this: -1x = -4. Now to get rid of the negatives. Just divide each side by negative one and your answer is x = 4.

Answer:

C

Step-by-step explanation:

the three binomial factors are (x+2)(x-1)(x-3)

Answer:

C

Step-by-step explanation:

Given a zero x = a then the corresponding factor is (x - a )

Here the zeros ( where the graph crosses the x- axis ) are at

x = - 2, x = 1 and x = 3

Thus the corresponding binomial factors are

(x - (- 2) ), (x - 1) and (x - 3), that is

(x + 2), (x - 1), (x - 3) → C

Answer:

(x,y)=(-4/5,10/19)

Step-by-step explanation:

x+2y=3

x-8y=-16

x+2y=3

-x+8y=16 (multiply both sides by-1)

10y=16

y=16/10

x+2(16/10)=3

x=-4/5

I just it into a calculator and got 162.72. Hope this helps you! Have a nice day and a nice rest of the holidays!

The product of 4.52 times by 36 is 162.72

Given,

4.52 times by 36

We need to find the product.

Example:

2.3 x 3.4 = 7.82

There are two numbers after the decimal point.

In 2.3 there is one number after the decimal point.

In 3.4 there is one number after the decimal point.

Now,

1 + 1 = 2 numbers

7.82 has two numbers after the decimal point.

We have,

4.52 times by 36

4.52 x 36 = 162.72

4.52 x 6 = 27.12

4.52 x 3 = 13.56

         4.52

       x   36

        27.12

     13.56        

     162.72

4.52 has two numbers after the decimal point.

162.72 has two numbers after the decimal point.

Thus the product of 4.52 times by 36 is 162.72

Remember "of" means multiply so you multiply 25% to 200

25% x 200

Convert 25% into a decimal

0.25 x 200 = 50

Answer:

15. [tex] x = 8 [/tex]

16. m<V = 103°

17. [tex] x = 14 [/tex]

Step-by-step explanation:

15. The figure given is quadrilateral. Sum of interior angles of a quadrilateral = 360°

Therefore:

[tex] (10x + 6) + (13x - 2) + (8x - 1) + (180 - 71) = 360 [/tex]

Solve for x

[tex] 10x + 6 + 13x - 2 + 8x - 1 + 109 = 360 [/tex]

Add like terms

[tex] 31x + 112 = 360 [/tex]

Subtract 112 from each side

[tex] 31x = 248 [/tex]

Divide both sides by 31

[tex] x = 8 [/tex]

16. The polygon is a hexagon. Sum of interior angles of a hexagon = 720. Therefore:

[tex] 90 + (7x + 3) + 128 + (5x + 8) + 111 + (9x - 19) = 720 [/tex]

Solve for x

[tex] 90 + 7x + 3 + 128 + 5x + 8 + 111 + 9x - 19 = 720 [/tex]

Add like terms

[tex] 321 + 21x = 720 [/tex]

Subtract 321 from each side

[tex] 21x = 399 [/tex]

Divide both sides by 21

[tex] x = 19 [/tex]

m<V = 5x + 8

Plug in the value of x

m<V = 5(19) + 8 = 95 + 8

m<V = 103

17. The polygon is a regular pentagon. This means each of the angles measures 108°. The sum of the interior angles all together is 540.

Therefore:

[tex] (9x - 18) = 108 [/tex]

Solve for x

[tex] 9x - 18 = 108 [/tex]

Add 18 to both sides

[tex] 9x = 126 [/tex]

Divide both sides by 9

[tex] x = 14 [/tex]

Answer:

Answer:

Step-by-step explanation:

Step one:

given data

weekly earnings= $375

Commission is 4% of sales.= 0.4

supposing sale is x, and the total earning is y

the expression for the total earning will be

y=375+0.4x

Step two:

for x= 2513, y will be

y=375+0.4(2513)

y=375+1005.2

y=1380.2

Hence  her total earnings for the week will be $1380.2

Answer:

The slope of the line represented by y = 5x is 5

Step-by-step explanation:

The form of the linear function is y = m x + b, where

To find the slope of a line from its equation compare the equation with the form of the linear function, then find the coefficient of x which is the slope of the line

∵ The equation of the line is y = 5x

→ Compare it with the form of the equation above

∵ The coefficient of x = 5

∴ m = 5

∴ The slope of the line represented by y = 5x is 5

Answer:13/6/7

Step-by-step explanation:

A line passes through point A(14,21). A second point on the line has an x-value that is 125% of the x-value of point A and a y-value that is 75% of the y-value of point A. Use point A to write an equation of the line in point-slope form.

Step-by-step explanation:

Answer:

76

Step-by-step explanation:

19 * 4 = 76

Answer:

Yes it is.

Step-by-step explanation:

Best way is to use percentages you know when estimating.

We know 50% is half.

50% of 242 is 121.

So it has to be more than 121.

10% of 242 is 24.2  so add that to 121 and you get 145.2

You are 60% so far. You just need 9% more.

Add another 10% which is 24.2 and you get 169.4, which is over but we used 10% instead of 9% so the estimate is reasonable and close.
