Step-by-step explanation: Just use the calculator next time, hope this helps.

Answer:

12.39669421

Step-by-step explanation:

30/2.42=12.39669421

Step-by-step explanation:

2(x+7)=72 no, because this only changes the value on the right side. so this equation is not about the same equality anymore.

x+7=18 yes, because both sides were transformed by the same operation (division by 2). the equality is still maintained.

2x+7=36 no, because 2x+7 is NOT equal to 2(x+7). resolving 2(x+7) is 2x+14.

x+14=36 no, because again, x+14 is NOT equal to 2(x+7).

(2×x) + (2×7) = 36 yes, because the left side is a valid transformation of 2(x+7).

2x+14=36 yes, because the left side is a valid transformation of 2(x+7).

Answer:

C. 15

Step-by-step explanation:

1. First, let's solve the system of equations; [tex]-m - n = 5, m - n = -3[/tex]

Solve -m - n = 5 for m.

Substitute -n - 5 for m in m - n = -3.

Substitute -1 for n in m = -n - 5.

2. Okay, now that we know m = -4 and n = -1, let's solve for m^2 -n^2.

Therefore, the answer is C. 15!

Answer:

Answer:

2hrs 30 mins on Friday or 2:30 in the afternoon on Friday

Step-by-step explanation:

it took the aero plane 8 h 45 minutes to travel

it reached its destination at 6 : 15 on Friday

to find the time and day it started, we just subtract the time it used to travel from the time and day it landed

which is;

8 45

-6 15

=2 30

that is 2hrs 30mins on Friday

Step-by-step explanation:

Answer:

(-3.2 , 12.3)

(0.7 , 3.6)

Step-by-step explanation:

The rule :

(x, y)→(x−7.5, y+6.8)

For the x - coordinate ; Subtract 7.5

For the y - coordinate `; add 6.8

First input : (4.3, 5.5)

Output :

x = 4.3 - 7.5 = - 3.2

y = 5.5 + 6.8 = 12.3

Output = (4.3, 5.5) →(-3.2 , 12.3)

Second input : (8.2, -3.2)

Output :

x = 8.2 - 7.5 = 0.7

y = - 3.2 + 6.8 = 3.6

Output = (8.2, -3.2)→(0.7 , 3.6)

The outputs obtained are :

(-3.2 , 12.3) and (0.7 , 3.6)

Answer:

  y = -3/4(x -2)

Step-by-step explanation:

You are given point (2, 0) on the new pipeline. To find the equation of it, you need to know the slope of the line on the graph. A careful look at the graph shows you the line goes through grid points that are separated by 4 units horizontally, and 3 units vertically. For a positive horizontal change, the vertical change is negative, so the slope is ...

  m = rise/run = -3/4

The point-slope form of the equation for a line is ...

  y -k = m(x -h) . . . . . . line with slope m through point (h, k)

For m = -3/4 and (h, k) = (2, 0), the equation is ...

  y = -3/4(x -2)

_____

Additional comments

If you use the distributive property to eliminate parentheses, the equation becomes ...

  y = -3/4x +3/2

The slope of the red pipeline can also be determined by considering the slope of the blue pipeline. The two marked points on that line have a horizontal separation of 3 and a vertical separation of 4. Its slope is ...

  m = rise/run = 4/3

The slope of the perpendicular (red) line is the opposite reciprocal of this:

  -1/m = -1/(4/3) = -3/4 . . . . as we determined from the red line's graph

The height of the wall of the building is 13.067 feet.

Pythagorean theorem states that in the right angle triangle the hypotenuse square is equal to the square of the sum of the other two sides. According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.

Given that the base of a 14-foot ladder is 5 feet from a building. The height of the building will be calculated as below:-

Applying the Pythagorean theorem to calculate the height of the building.

H² = P² + B²

14² = P² + 5²

P² = 14² - 5²

P = √171 = 13.07 feet

Therefore, the height of the wall of the building is 13.067 feet.

Answer:

let Karen's music library be represented by K

let Clarann's music library be represented by C

C = K +18

C +K =40

put C = K +18 into (C +K =40)

K + 18 +K =40

2K +18 = 40

collect like terms

2K =40 -18

2K =22

divide both sides by 2

K =11

since C = K+18

C= 11 +18

C =29

Karen's music library contains 11 playlists while Clarann's music library contains 29 playlists

Answer:

10 percent is the answer

Manuel needs 20 liters of the 8% and 5 liters of 20% mixtures to be mixed so as to get 30 liters of a mixture of water and 10% lemon juice.

Let x represent the amount of 8% lemon juice in liters and y represent the amount of 20% lemon juice in liters.

Since Manuel wants to produce a 30 liters mixture from 8% lemon juice and 20% lemon juice, hence:

x + y = 30      (1)

Also, Manuel wants 30 liters of a mixture of water and 10% lemon juice, hence:

8% of x + 20% of y = 10% of 30 liters

0.08x + 0.2y = 3         (2)

Solving equation 1 and 2 simultaneously; multiply equation 1 by 0.2 and subtract equation 2 from the result:

0.12x = 3

x = 25 liters

x + y = 30

25 + y = 30

y = 5 liters

Manuel needs 20 liters of the 8% and 5 liters of 20% mixture

Step-by-step explanation:

7(0)+y=10

y=10

Answer: (0, 10)

Step-by-step explanation:

The given expression is in the standard form of linear equations: Ax + By = C, where A and B are constants.

The definition of y-intercept is the point that intersects with the y-axis, meaning that the [x] value of the point will be zero.

To find the y-intercept of an equation, substitute the [x] variable with 0, as mentioned above, the [x] value of a y-intercept is 0.

[tex]7x+y=10\\[/tex]

[tex]7(0)+y=10[/tex]

[tex]0+y=10[/tex]

[tex]y=10[/tex]

As we find the [y] value is 10, while the given [x] value is 0, therefore, the y-intercept of [tex]7x+y=10[/tex] is [tex]\boxed{(0,10)}[/tex].

Answer:

9.75, 2, and 56.25

Step-by-step explanation:

Since it's 4 movie tickets, 2 popcorns (which are $6.25),

4(9.75) + 2(6.25 -> Popcorn) + 4.75

= 39 + 12.5 + 4.75

= 39 + 17.25

= $56.25

As for the total cost,

4 * 9.75 = 39

2 * 6.25 = 12.5

1 * 4.75 = 4.75

Answer: 1. x=-7 2. m=6

Step-by-step explanation:

1. 5 + x=-2

to get the x by itself, you need to subtract 5 from both sides

5-5 +x = -2-5

there for 0 + x = -7 which means x=-7

2. to get 8m to just m, you need to divide 8m by 8. and what you do to one side of the equation, you need to do to the other. therefore 8m/8=48/8 and 48/8=6. therefore m=6

Answer:

1. 5+x=-2

x=-2-5

x= -7
