Răspuns:

38

Explicație pas cu pas:

Dat fiind :

Diferența dintre numere = 38

Subtractorul = x

Scădere = 76

Diferența dintre numere;

Scădere - scădere = diferență

76 - scădere = 38

76 - 38 = subtractor

Subtractor = 38

Answer:

= 7/12

Answer:

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>9/5

Step-by-step explanation:

2/3x-1/5(+1/5)>1(+1/5)

[add 1/5 on both sides]

2/3x (÷3/2)>6/5 (÷3/2)

[flip 2/3 to 3/2 so that they cancel out]

x>9/5

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

Answer:

14 units²

Step-by-step explanation:

The area (A) of a triangle is calculated as

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )

Here b = 7 and h = 4 , so

A = [tex]\frac{1}{2}[/tex] × 7 × 4 = [tex]\frac{1}{2}[/tex] × 28 = 14 units²

Answer:

( 1, 5 )

x = 1

y = 1

Step-by-step explanation:

y = x + 4

2x + 3y = 17

Since they gave us the value of "y" we can use that and substitute it into the equation to find what "x" is.

2x + 3y = 17

2x + 3 ( x + 4 ) = 17

Distributive Property

2x + 3 * x + 3 * 4 = 17

2x + 3x + 12 = 17

Combine Like Terms ( 2x and 3x)

5x + 12 = 17

Subtract 12 on both sides of the equation

5x + 12 - 12 = 17 - 12

5x = 5

Divide by 5 on both sides to isolate the variable

5x/5 = 5/5

x = 1

Now that we have what "x" is, we can substitute that into one of the equations to get the value of "y"

y = x + 4

y = 1 + 4

y = 5

x = 1

y = 5

( x, y )

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:

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:

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 price of ribbon is $0.63 per meter.

Step-by-step explanation:

It is given that:

Cost of 3 meter ribbon = $1.89

Unit price per meter = [tex]\frac{1.89}{3}[/tex]

Unit price per meter = $0.63 per meter

Therefore,

The price of ribbon is $0.63 per meter.

Answer:

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

⇔ 5x + 2 - 2x + 2 = 3x + 4

⇔ 3x + 4 = 3x + 4

⇔ 4 = 4

⇒ infinite solutions
