Step-by-step explanation:

From the question we are told that

Preston Earns \triangle x=$64-$81

Number of days D=5 days

Generally the average amount of money made by Preston is given by

[tex]X_a_v_g=\frac{64+81}{2}[/tex]

[tex]X_a_v_g=\$72.5[/tex]

Generally  a reasonable estimation of how much Preston will earn if he works 5 days P is mathematically given by

[tex]P=72.5*5[/tex]

[tex]P=\$362.5[/tex]

Answer

{3,1}

Explaination

3 +4=7[1]    x = -4y + 7

// Plug this in for variable  x  in equation [2]

  [2]    4•(-4y+7) - 3y = 9

  [2]     - 19y = -19

// Solve equation [2] for the variable  y

  [2]    19y = 19

  [2]    y = 1

// By now we know this much :

   x = -4y+7

   y = 1

// Use the  y  value to solve for  x

   x = -4(1)+7 = 3

Solution :

{x,y} = {3,1}

Answer:

x = 20

Step-by-step explanation:

added together, the angles make 180

3x + 80 + 2x = 180

subtract 80 from both sides of the equation

3x + 80 - 80 + 2x = 180 - 80

combine like terms

5x = 100

divide both sides by 5

5x/5 = 100/5

x = 20

Answer:

x = 20

Step-by-step explanation:

added together, the angles make 180

3x + 80 + 2x = 180

subtract 80 from both sides of the equation

3x + 80 - 80 + 2x = 180 - 80

combine like terms

5 x = 100

divide both sides by 5

5x/5 = 100/5

x = 20

Answer:

0.59

Step-by-step explanation:

first you have to find x, you do that by getting x by its self. when you do this you do the opposite arithmetic (equation sign like - or +) on both sides of the equal sign. for example since its plus 3.78 you have to subtract 3.78 on both sides of the equal sign, so on so on till you are left with only x on one side of the equal sign

Step-by-step explanation:

Height of buiding h= 9m

Lenght from building l= 12m

let the length of the rope be x=???

Applying Pythagoras theorem

x^2=h^2+l^2

x^2= 9^2+12^2

x^2= 81+144

x^2=225

square both sides

x=√225

x=15 m

Hence the length of the rope is 15 m

The ordered pair of a unit circle is represented as:

[tex](x,y) \to (\cos(\theta),\sin(\theta))[/tex]

The given parameters can be represented as:

[tex](x,y) \to (\frac{1}{2},\frac{\sqrt 3}{2})[/tex]

Recall that:

[tex](x,y) \to (\cos(\theta),\sin(\theta))[/tex]

Compare the above representation to:

[tex](x,y) \to (\frac{1}{2},\frac{\sqrt 3}{2})[/tex]

This means:

[tex]\cos(\theta) = \frac{1}{2}[/tex] and [tex]\sin(\theta) = \frac{\sqrt 3}{2}[/tex]

Answer:

A) 6 x² - 7x - 20

Step-by-step explanation:

Explanation:-

Given p(x) = 2 x-5 and r (x) = 3 x +4

(pr)(x) = p(x) r(x)

         = (2x -5)( 3 x +4)

        = 2x(3x +4) -5( 3x +4)

       = 6 x² + 8x - 15 x - 20

       =  6 x² - 7x - 20

(pr)(x) = 6 x² - 7x - 20

Answer:

A is 20°

Step-by-step explanation:

Given sin3A = (√(3))/2. To find A we firstly take the sin^-1 of both sides and we have:

3A = sin^-1(√(3)/2)

We know that sin60° = √(3)/2. Therefore, sin^-1(√(3)/2) = 60°. Hence, we have

3A = 60°.

To get A, divide both sides by 3:

.A = 20°. Therefore, A is 20°.

Answer:

160/100 X 60 = 96

160 - 96 = 64

Answer:

A solution of the system of equation given in the question is;

(2) x = 7 and y = 23

Step-by-step explanation:

The given system of equation are;

2·x + 3·y = 83...(1)

y = 2·x + 9...(2)

Substituting the value of y = 2·x + 9 from equation (2) into equation (1) gives;

2·x + 3·y = 2·x + 3 × (2·x + 9) =  83

∴ 2·x + 6·x + 27 = 83

8·x = 83 - 27 = 56

x = 56/8 = 7

x = 7

By substituting the value of x = 7 derived above into equation (1), we have;

y = 2·x + 9

Where;

x = 7

y = 2 × 7 + 9 = 14 + 9 = 23

y = 23.

Answer:

what class is this ???

Step-by-step explanation:

The value of each measure are,

8. ED = 16 ft

9. DF = 21 ft

10. m ∠DEF = 103°

An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.

Given that;

In trapezoid DEFG,

⇒ EG = 21 ft and m ∠DGF = 77°

Now, We know that;

In trapezoid, The sum of the angles on the same side is equal to 180°.

Hence, We get;

⇒ ∠ DGF = ∠ GDE = 77°

And, We get;

⇒ ∠ DEF + ∠ EDG = 180°

⇒ 77° + ∠ DEF = 180°

⇒ ∠ DEF = 180° - 77°

⇒ ∠ DEF = 103°

Since, In trapezoid opposite non parallel line are equal in length.

Hence, We get;

⇒ ED = FG

⇒ ED = 8 + 8

⇒ ED = 16

In trapezoid, Diagonal are equal in length.

Hence, We get;

⇒ DF = EG

⇒ DF = 21 ft

Answer:

Step-by-step explanation:

From the given graph the line is straight ,so it means that the relation between x and y is directly proportional

(or) you can also say that at each point the slope of the line is same

slope =y/x ,  slope= 26/2  = 65/2 = 117/9 =13

hence slope is same that's why relation between x and y is direct relation

y∝ x

y=k*x

k=y/x

8-y/x

Step-by-step explanation:

Here, we want to select expressions on the table having a solution of 10, given the value of x and y

For ;

-x(10) = -1(10) = -10

x + y + 7

-1 +2 + 7 = 8

8 -y/x = 8-(2/-1) = 8 + 2 = 10

-5(x)(y)

= -5(-1)(2) = 10

16-x + y - 7

16-(-1) + 2 - 7

16 + 1 + 2 - 7 = 12
