Step-by-step explanation:

use mathw a y to help solve questions like this

A)

   a

———=8       :a=64

5+3  

Steps:Multiply both sides by 8

     ———-=8  ·   8

      5+3

B)

3b/7 - 1 = 5

Add 1 in both sides

3b/7 - 1 + 1 = 5 + 1

3b/7 = 6

Multiply both sides by 7 and then divide by 3.

3b/7 . 7/3 = 6 . 7/3

b = 2.7

b = 14

Answer:

3 miles

Step-by-step explanation:

Slope is simply the change in position per unit rate. We could conclude that the steepness of the Applachian is the rate of change in position per unit time. Since the distance hiked on the Applachian is said to be 3 miles per hour, then we can conclude that the slope of the applachian is 3 miles

This is the change in miles / change in time.

Chang in miles = 3

Change in time = 1

Slope = 3/1

Slope = 3

Answer:

I think the asnwer A or B !!

Step-by-step explanation:

Answer:

Correct Answer is B. The first equation in B is the sum of the equations in A, while the other is obtained  by multiplying the first equation in A by 2.

Step-by-step explanation:

As given,

A : 6x + 8y = -10     .......equation (1)

     2x - 5y = 12      .......equation (2)

B : 8x + 3y = 2         .......equation (1)

  12x + 16y = - 20    .......equation (1)

Correct Answer is B. The first equation in B is the sum of the equations in A, while the other is obtained  by multiplying the first equation in A by 2.

Proof :

The first part says that ,

Sum of equation (1) of A and equation (2) of A = Equation (1) of B

Firstly , find the Sum of equation (1) of A and equation (2) of A

⇒6x + 8y + 2x - 5y = -10 + 12

⇒8x + 3y = 2

this is same as equation (1) of B

So, it satisfies the first part

The second part says that,

The equation (2) of B is obtained by multiplying the first equation in A by 2.

It means , if the equation (1) is multiplied by 2 = equation (2) of B

Firstly , if the equation (1) is multiplied by 2 , we get

2 ( 6x + 8y = -10 )

⇒ 2 ( 6x + 8y ) = 2 ( -10)

⇒ 12x + 16y = -20

this is same as equation (2) of B

So, it satisfies the second part.

Equation of the ellipse = 3x² + 5y² = 32

The equation of an ellipse is given by,

[tex]\sf \dfrac{x^2}{a^2} +\dfrac{y^2}{b^2} =1[/tex]

Given that the ellipse passes through the point (-3, 1)

Hence,

[tex]\sf \dfrac{(-3)^2}{a^2} +\dfrac{1^2}{b^2} =1[/tex]

Cross multiplying we get,

Multiply by 4 on both sides,

Also by given the ellipse passes through the point (2, -2)

Substituting this,

[tex]\sf \dfrac{2^2}{a^2} +\dfrac{(-2)^2}{b^2} =1[/tex]

Cross multiply,

Subtracting equations 2 and 1,

Substituting in 2,

Substituting the values in the equation for ellipse,

[tex]\sf \dfrac{x^2}{32/3} +\dfrac{y^2}{32/5} =1[/tex]

[tex]\sf \dfrac{3x^2}{32} +\dfrac{5y^2}{32} =1[/tex]

Multiplying whole equation by 32 we get,

3x² + 5y² = 32

What Are The Options?

Step-by-step explanation:

Answer:

0.42

Step-by-step explanation:

given:

P (penny) = 1/4

P (dime) = 1/3

since the only other possibility is to pick a nickel, hence

P (nickel)

= 1 - 1/4  - 1/3

= 5/12

= 0.4166667

= 0.42 (nearest hundredth)

Answer:

25%

Step-by-step explanation:

Divide 89.99 or 90 (since you are rounding) by 120, and you get .7499 or 75%.  You have 25% ($30) as the discount because 90 is 75% of $120.

Please check the explanation.

Step-by-step explanation:

We know that a pentagon is a polygon with 5 sides and 5 angles.

Given the polygon with 5 angles.

A pentagon is a polygon with 5 sides and 5 angles.

The angles of the given pentagon are:

∠P = (4x + 2)°

∠Q = 132°

∠R = (4x - 10)°

∠S = (5x - 11)°

∠T = 128°

We know that the sum of the measures of the interior angles of a pentagon is 540 degrees.

Therefore,

∠P + ∠Q + ∠R + ∠S + ∠T = 540°

(4x + 2)° + 132° + (4x - 10)° + (5x - 11)° + 128° = 540°

group similar elements

4x + 4x + 5x + 2 + 132 - 10 - 11 + 128 = 540

simplify

13x + 241 = 540

subtract 241 from both sides

13x + 241 - 241 = 540 - 241

13x = 299

divide both sides by 13

13x/13 = 299/13

x = 23

Thus, the value of x = 23

Therefore, the measure of angle ∠S is:

m∠S = (5x - 11)°

        = (5(23) - 11)°

        = (115 - 11)°

        = 104°

Thus,

m∠S = 104°
