Answer:

The CD player's price decreased by 35%

Answer:

5x + 2 - 2(x - 1) = 3x + 4

⇔ 5x + 2 - 2x + 2 = 3x + 4

⇔ 3x + 4 = 3x + 4

⇔ 4 = 4

⇒ infinite solutions

Answer:

  Perimeter of the rectangle  = 6 x +20

 Perimeter of the rectangle  = 0 x² + 6 x + 20

Step-by-step explanation:

Step(i):-

Given that the length of the rectangle = 2x +3

Given that the width of the rectangle = x +7

Perimeter of the rectangle   = 2(length + width)

Step(ii):-            

  Perimeter of the rectangle   = 2(length + width)

                                                  = 2(2 x +3 + x+7)

                                                 =  4x +6+2x+14

                                                 = 6 x +20        

Final answer:-

 Perimeter of the rectangle  = 6 x +20

 Perimeter of the rectangle  = o x² + 6 x + 20

Answer:

X-intercept is (9,0) and y-intercept is (0,21)

Step-by-step explanation:

X-intercept:

7x+3(0)=63

7x=63

x=9

y-intercept:

7(0)+3y=63

3y=63

y=21

Answer:

Step-by-step explanation:

A proportion is simply a statement that two ratios are equal.  In problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. To find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.

Answer:

Write a proportion using the ratios. Find the cross products. If the cross products are equal, then the ratios form a proportion.

Answer:

The solution of the equation    y = 36

Step-by-step explanation:

Explanation:-

Given equation -3x-y =-51

Given that x =15 in equation -3x-y=-51

                 ⇒        - 3(15) - y = -51

                ⇒         - 15 - y =-51

                 ⇒         -15+ 51 = y

               ⇒            y = 36

Answer:

180° on a straight line

180 = 18x - 54

add 54 to both sides

234 = 18x

X = 234/18

X= 13°

6 X 13 - 5 = 73

12 X 13 - 49 = 107

107 + 73 = 180

Answer:

(C) x=50

Step-by-step explanation:

[tex]\frac{3}{5 }x -7=23[/tex]

[tex]\frac{3x}{5} -7=23[/tex]

[tex]\frac{3x}{5} -7+7=23+7[/tex]

[tex]\frac{3x}{5}=30[/tex]

[tex]3x=30* 5[/tex]

[tex]3x=150[/tex]

[tex]x=50[/tex]

Answer:

(C) X = 50

Step-by-step explanation:

(3/5)*x-7 = 23 // - 23

(3/5)*x-23-7 = 0

3/5*x-30 = 0 // + 30

3/5*x = 30 // : 3/5

x = 30/3/5

x = 50  (Sorry if it's wrong)

Answer:

(7z-3)(z-5)

Step-by-step explanation:

7z^2-38z+15

(7z-3)(z-5)

Answer:

(z - 5)(7z - 3)

Step-by-step explanation:

Given

7z² - 38z + 15

Consider the product of the factors of the coefficient of the z² term and the constant term which sum to give the coefficient of the z- term

product = 7 × 15 = 105 and sum = - 38

The factors are - 35 and - 3

Use these factors to split the z- term

7z² - 35z - 3z + 15 ( factor the first/second and third/fourth terms )

= 7z(z - 5) - 3(z - 5) ← factor out (z - 5) from each term

= (z - 5)(7z - 3) ← in factored form

Answer:

-1y + z

Step-by-step explanation:

2y + z - 3y [Given Expression]

-1y + z [Combine like-terms]

Answer:

-y + z

Step-by-step explanation:

2y + z −3y = 2y + z + −3y = ( 2y + −3y ) + ( z ) = −y + z

Answer:

Step-by-step explanation:

B The number that is 6 to the right of 1 on the number line

Answer:

x= -2

Step-by-step explanation:

Let's solve your equation step-by-step.

15−10x=5(x+9)

Step 1: Simplify both sides of the equation.

15−10x=5(x+9)

15+−10x=(5)(x)+(5)(9)(Distribute)

15+−10x=5x+45

−10x+15=5x+45

Step 2: Subtract 5x from both sides.

−10x+15−5x=5x+45−5x

−15x+15=45

Step 3: Subtract 15 from both sides.

−15x+15−15=45−15

−15x=30

Step 4: Divide both sides by -15.

−15x/-15 = 30/ -15  

x= −2

Answer:

80 spotted frogs

Step-by-step explanation:

We can write a ratio

spotted frogs:frogs

12:180

x:1200

To solve we just multiply 12*6.66667 (because this is what we multiplied 180 to get to 1200)

the answer is 80
