what is the answer of -6n-2n=16

Answers

Answer:

n = - 2

Step-by-step explanation:

Given

- 6n - 2n = 16, that is

- 8n = 16 ( divide both sides by - 8 )

n = - 2

Step-by-step explanation:

-6n-2n=16

-6n+-2n=16

(-6n+-2n)=16

-8n=16 divide both sides by - 8

-8n÷-8= 16÷ - 8

n= - 2

Triangle WXY is isosceles. ∠YWX and ∠YXW are the base angles. YZ bisects ∠WYX. m∠XYZ = (15x)°. m∠YXZ = (2x + 5)°. What is the measure of ∠WYX? 5° 15° 75° 150°

Answers

The measure of ∠WYX in the given isosceles triangle is; 150°

Angles in a triangle

We are told that Triangle WXY is isosceles..

We are given the base equal angles as;

∠YWX∠YXW

YZ bisects ∠WYX and m∠XYZ = (15x)°. Thus;

∠WYX = 2(15x)° = (30x)°

Now, we are told that m∠YXZ = (2x + 5)°

Thus, since sum of angles in a triangle is 180°, then;

30x + (2x + 5)° + (2x + 5)° = 180

34x + 10 = 180

34x = 170

x = 170/34

x = 5

Thus;

∠WYX = (30x)° = (30 × 5) = 150°

A farmer saw some chickens and pigs in a field. He counted 30 heads and 84 legs. Determine exactly how many chickens and pigs
he saw?

Answers

Answer:

51

Step-by-step explanation:

Given parameters:

Number of heads  = 30 heads

Number of legs  = 84 legs

Unknown:

Number of chickens and pigs = ?

Solution:

Since a chicken has one head, the number of chicken is the same as the number of heads;

  Number of chicken  = 30

A pig has 4 legs,

   Number of pigs  = [tex]\frac{84}{4}[/tex]   = 21pigs

Total number of pigs and chickens = 30chickens + 21 pigs  = 51

12w+10=2(3w+35)
How do I solve this?

Answers

Answer:

w = 10

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDASEquality Properties

Step-by-step explanation:

Step 1: Define equation

12w + 10 = 2(3w + 35)

Step 2: Solve for w

Distribute 2:                              12w + 10 = 6w + 70Subtract 6w on both sides:      6w + 10 = 70Subtract 10 on both sides:       6w = 60Divide 6 on both sides:            w = 10

Step 3: Check

Plug in w to verify it's a solution.

Substitute:                    12(10) + 10 = 2(3(10) + 35)Multiply:                        120 + 10 = 2(30 + 35)Add:                              130 = 2(65)Multiply:                        130 = 130

Here we see that 130 does indeed equal 130.

∴ w = 10 is a solution of the equation.

Step-by-step explanation:

Solve this equation by isolating for w.

Step-by-step explanation:

Perimeter is the sum of all the sides

P = 3y - 2 + 2y + 2 + 2y - 2 + y + 2y - 1 =10y - 3

Answer:

P = 10y - 3

Step-by-step explanation:

Perimeter is dettermined by adding all the outside surfaces information together.

Watch:

First, set up:

(3y - 2) + (2y + 2) + (2y - 2) + (y) + (2y - 1)

Now add the common alikes.

(3y + 2y + 2y + y + 2y) = 10y

(-2 + 2 - 2 - 1) = -3

1.  -3e-10 ≤ -4  => first add 10 to both sides

     +10    +10

-3e ≤ 6 => Then divide negative three on both sides.

/-3    /-3

e ≥ -2 => Since, we divided by a negative the sign switches.

2.  8c+4 ≤ 4(c-3) => First, Distribute the 4.

8c+4 ≤ 4c -12 => Next, Subtract 4 on both sides.

8c ≤ 4c -16 => then, subtract 4c on both sides.

-4c   4c

4c ≤ 16 => Finally, you divided 4 on both sides.

c ≤ 4

3. 5(x-1) < 3x +10 -8x => First, you add like terms.

5(x -1) < -5x +10 => Next, you distribute the 5.

5x -5 < -5x +10 => Then, you add five in both sides.

5x < -5x +15 => After that you add -5x in both sides.

Find the x and y intercepts for the equation 2x + 7y = 42.

Answers

Answer:

see explanation

Step-by-step explanation:

Given

2x + 7y = 42

To find the x- intercept let y = 0 in the equation and solve for x

2x + 7(0) = 42, that is

2x = 42 ( divide both sides by 2 )

x = 21 ← x- intercept or (21, 0 )

To find the y- intercept let x = 0 in the equation and solve for y

2(0) + 7y = 42 , that is

7y = 42 ( divide both sides by 7 )

y = 6 ← y- intercept or (0, 6 )

10x - (2x + 9) = -3 (15 - 4x)

Answers

Answer:

x=9

Step-by-step explanation:

First, distribute the negative sign, changing (2x+9) to -2x-9

next, distribute. 10x+−2x+−9=(−3)(15)+(−3)(−4x)

then, combine like the like terms  (10x+−2x)+(−9)=12x−45

then you get  8x+−9=12x−45, and you will subtract 12x from both sides, resulting in −4x−9=−45. To get -4x by itself, add 9 to both sides

lastly, divide both sides by -4

x=9

Answer:

x = 9

Step-by-step explanation:

Distribute

10x - (2x + 9) = -3 (15 - 4x)

10 − 2 − 9 = − 3 (15 − 4)

Combine like terms

8 − 9 = − 3 (15 − 4 )

Rearrange terms

8 − 9 = − 3 (− 4 + 15)

Distribute

8 − 9 = 12 − 45

Add 9 to both sides of the equation

8 − 9 + 9 = 12 − 45 + 9

If the point of the preimage is (5,2) and the point of the image is (1,2), what RULE was applied to the preimage to obtain the image?

B) (x + 4, y)
C) (x - 4, y)
D) (x, y - 4)

Answers

Answer: Choice C)  (x-4, y)

Explanation:

We have x = 5 turn into x = 1. We need to subtract 4 from the x coordinate to get this. Therefore x turns into x-4.

The y coordinate stays at y = 2 the entire time, so y isn't altered. We have y map to y.

3. How long is 75% of 60 minutes?

(please provide explanation for both)

Answers

Answer:

6 minutes

45 minutes

Step-by-step explanation:

There are a few ways I solve problems with percentages. First... it is easy to find 10% of 60 because you just divide 60 minutes by 10 to find the answer. (you do this because 10% is 100% divided by 10)

If you know what 10% of 60... (6) and you are trying to find 75%... all you have to do is multiply the 10% value by 7 to find 70%...if you do this... you get 70% = 42 minutes.

To find the remaining 5%.... just add half of the 10% value to 42 minutes. (1/2 of 6 = 3)

42 + 3 = 45

2.   10% of 60 minutes long, means duration of 6 minutes.

⇒ T/60×100 =10
