PLEASE HELP ASAP!!!!

Step-by-step explanation:

If two lines have the same slope and the same y-intercept, there are infinite solutions.

If two lines have the same slope and different y-intercepts, there are zero solutions.

Otherwise, if the two lines have different slopes, then there is one solution.

The slope of the first line is 3/8.  The slope of the second line is 16/32 = 1/2.  The slopes are different, so there is only one solution.

The solution of the given system of equations is (x, y) = (8.75, 2).

Given: System of equations

3x - 8y = 10                           …(1)

16x - 32y = 75                       …(2)

Consider equation (2).

⇒ 16x - 32y = 75

Dividing both sides by 16, we get:

⇒ x - 2y = 75/16

⇒ x = 2y + 75/16                  …(3)

Now, substitute the value of x = 2y + 75/16 in equation (1), we get:

⇒ 3(2y + 75/16) - 8y = 10

⇒ 6y + 225/16 - 8y = 10

⇒ 2y = 225/16 - 10

⇒ 2y = (225 - 160)/16

⇒ 2y = 65/16

⇒ y = 65/32

⇒ y ≈ 2

Now, put the value of y = 65/32 in equation (3), we get:

⇒ x = 2(65/32) + 75/16

⇒ x = (65/16) + (75/16)

⇒ x = 140/16

⇒ x = 8.75

Therefore, the solution for the given simultaneous equation is;

(x, y) = (8.75, 2)

What is that supposed to mean

Answer:

r = - 8

Step-by-step explanation:

First, put -3r + 16 and -r - 4r equal to each other. -3r + 16 = -r - 4r, then combine the -r -4r to equal -5r so the equation is easier to solve. -3r + 16 = -5r, then add 3r to both sides to get 16 = = -2r and then divide both sides by -2 to get r = -8.

Answer: 21

Step-by-step explanation:

y = x + 8

Subtract 8 from both sides

y - 8 = x

Answer:

38.08mph

Step-by-step explanation:

The question tells us that the speed of

Speed of boat = 35mph

Wind blowing = 15mph

We have to use the pythagorean theorem in other to find the resulting speed.

So,

Speed² = 35² + 15²

Such that

Speed = √35² + 15²

Speed = sqr(1225 + 225)

Speed = sqr(1450)

Speed = 38.08

The approximate resulting speed of the boat is therefore 38.08mph

Answer:

67/24

Step-by-step explanation:

Remember PEMDAS

First you solve the parenthesis which is 11/12.

Then do exponents 2^4=16

For division do left to right so 2/3 ÷ 16 = 1/24

and the other division is 11/12 ÷ 1/3 = 11/4

Add the two 1/24 + 11/4 = 67/24

67/24 is the answer

Answer: 5 people

Step-by-step explanation:

For this word problem, we can use the description in the problem to construct an equation. Let's use x for number of people.

3.5x+5.5x+6=51         [combine like terms]

9x+6=51                      [subtract both sides by 6]

9x=45                         [divide both sides by 9]

x=5

Answer:

scientific notation = 2.226 * 10^8

Standard form = 222600000

As it is 22.26 * 10^7

Step-by-step explanation:

(5.3x10^4)(4.2x10^3)

Since all the numbers are being multiplied by each other, one can use the associative property to change the order in which they are multiplied.

5.3 x 10^4 x 4.2 x 10^3

= 5.3 * 4.2 * 10^4 * 10^3

= 22.26 * 10^7

Either convert back to scientific notation, standard form or keep as it is.

scientific notation = 2.226 * 10^8

Standard form = 222600000

As it is 22.26 * 10^7

Step-by-step explanation:

1. 13x + 2 = 4x + 38

   9x + 2 = 38

    9x = 36

     x = 4

2. 6(2/3 + q/6 = 5/6q + 1/3)

      4 + q = 5q + 2

    4 - 4q = 2

     -4q = -2

       q = 2/4= 1/2

3. 6n + 24 = -18

    6n = -42

     n = -7

4. -11 + 3b + 15 = 7

   3b + 4 = 7

    3b = 3

    b = 1

5. 5 + 2n + 2 = 2n

   2n + 7 = 2n

   0 ≠ 7

6. 7 - 3r = r - 8  - 4r

  7 -3r = -3r - 8

  0 ≠ -15

7. 14v + 6 = 10 + 14v - 4

  14v + 6 = 14v + 6

  0 = 0

The answer is D.

Turning fractions into decimals will help you eliminate answers!!

How I got D:

-2 3/4 can be turned into -2.75 by dividing 3/4.

-2 3/4 is the smallest number out of all of them so it has to be first.

-2.67 is the second smallest value.

3/5 is .60 making it the third smallest value.

4 is the second largest value.

17/4 is 4.25, which is the largest.

A is not correct because -3/5 is not the smallest number.

B Is not correct because the largest number is 17/4.

C is not correct because -2.67 is not the smallest number.

Answer:

15.155857

Step-by-step explanation:

I used a calculator by typing [tex]\sqrt{229.7}[/tex]

The angle "b" and the angle "d" are both the same angle measure. In other words, they are opposite angles that share the black dot in the middle. Angle "a" and angle "c" are both opposite angles which make them the same. They can also be called congruent angles. Even if they are facing a different direction, they are the same.

Therefore, the answer is 130 degrees

Best of Luck!

answer:

130 degrees

explanation:

the angles "a" & "c" are opposite (also called congruent) so they are the same.
