2. Definition of supplementary angles

3. [tex]\angle 1 + \angle 2 = \angle 1 + \angle 3[/tex]

4. [tex]\angle 2 = \angle 3[/tex]

5. Definition of congruent angles

Step-by-step explanation:

Required

Fill in the gaps

1. Given

Supplementary angles: [tex]\angle 1[/tex] and [tex]\angle 2[/tex]

Supplementary angles: [tex]\angle 1[/tex] and [tex]\angle 3[/tex]

2. Supplementary angles add up to 180.

So:

[tex]\angle 1 + \angle 2 = 180[/tex]

[tex]\angle 1 + \angle 3 = 180[/tex]

3. Apply transitive property on (2)

[tex]\angle 1 + \angle 2 = 180[/tex] and [tex]\angle 1 + \angle 3 = 180[/tex], then

[tex]\angle 1 + \angle 2 = \angle 1 + \angle 3[/tex]

4. Subtract [tex]\angle 1[/tex] from both sides

[tex]\angle 1 - \angle 1 + \angle 2 = \angle 1 + \angle 3 - \angle 1[/tex]

[tex]\angle 1 - \angle 1 + \angle 2 = \angle 1 - \angle 1+ \angle 3[/tex]

[tex]\angle 2 = \angle 3[/tex]

This property is called the subtraction property

5. If [tex]\angle 2 = \angle 3[/tex],

Then [tex]\angle 2[/tex] and [tex]\angle 3[/tex] are congruent

Answer:

A compound inequality contains at least two inequalities that are separated by either "and" or "or". ... A number is a solution to the compound inequality if the number is a solution to both inequalities. It can either be written as x > -1 and x < 2 or as -1 < x < 2.

Isolate the variable by dividing each side by factors that contain the variable.

Answer:

Angle D = m∠D= 50°

Step-by-step explanation:

In ΔCDE we are given: 3 angles

m∠C=(5x+18) ∘

m∠D=(3x+2) ∘

m∠E=(x+16) ∘ .

The sum of angles in a triangle = 180°

Hence:

m∠C + m∠D + m∠E = 180°

(5x+18)° + (3x+2)° + (x+16)° = 180°

5x + 18 + 3x + 2 + x + 16 = 180°

5x + 3x + x + 18 + 2 + 16 = 180°

9x +36= 180°

Subtract 36 from both sides

9x + 36 - 36 = 180° - 36°

9x = 144°

x = 144°/9

x = 16

From the above question, we are asked to find:angle D (m∠D )

Hence:

m∠D=(3x+2)°

m∠D=( 3 × 16 + 2)°

m∠D=(48 + 2)°

m∠D= 50°

Answer:

0.33333333

Step-by-step explanation:

4 divided by 12 would be written like this: 4/12

it's always good to simplify if possible, so it should look like this: 1/3

3 which is the denominator would be divided by 10, so 3/10 = 0.33333333

0.33333333 is the answer because the numerator is how many times you multiply it, and 1*0.33333333 = 0.33333333

1. Collect like terms.

(6g^2+2g^2-3g^2)+(6-2)+(-4g+5g+2g)

2. Simplify

Sorry i'm hoping that helps, i'm on a school computer i cant see the picture you attached but i did 6g^2 + 6 - 4g + 2g^2 - 3g^2 + 5g + 2g - 2 because that's what it seemed you were asking.

Answer: [tex]0.1x-0.25y<0[/tex]

Step-by-step explanation:

Let the two numbers be x and y

10% of the first number will be;

10% of x

[tex]=\frac{10}{100} of x[/tex]

[tex]=0.1x[/tex]

25% of the other number will be ;

25% of y

[tex]0.25y[/tex]

If 10% of the first number is less than 25% of the other number, this is expressed as;

[tex]0.1x<0.25y[/tex]

[tex]0.1x-0.25y<0[/tex]

Hence the required inequality is [tex]0.1x-0.25y<0[/tex]

Answer:

96 apple pies, 64 cherry pies, and 48 blueberry pies.

Step-by-step explanation:

6 + 4 + 3 = 13, and 208 / 13 = 16. Now multiply each number in the ratio by 16, so 6 x 16 = 96, 4 x 16 = 64, and 3 x 16 = 48. You can check your answer by adding all 3 numbers and making sure it adds up to 208. Hope that helps

Answer:

m = 1/2

Step-by-step explanation:

To find the slope, all you have to do is find the rise and divide it by the run. Rise means how many units you move up or down from point to point. Run means how far left or right you move from point to point.

You can pick any two points on the line. Let's say I choose (10, 5) and (20, 10).

Let's look at the y coordinates first. You have 5 and 10. To get from 5 to 10,  you have to go up 5 units. Your rise is 5. Let's look at the x coordinates now. To get from 10 to 20, you have to go up 10 units. Your run is 10.

As I said before, the slope is rise/run. In this case, we have 5/10, which can be simplified to 1/2. Your slope is 1/2.

Note that any two points on this would give you the same answer of 1/2 for this line. If I had picked (30, 15) and (70, 35), I would still get 1/2.

Hope this helped!

Answer:

4 and 6

Step-by-step explanation:

Judging by the table and how x = 1 and y = 2, you can estimate that y is twice as much as x.

This is supported by the equation, if you take 2 and multiply it by x (1) and take 3 and multiply it by y (2), then add the 2x1 (2) and 3x2 (6), you should get 8.

Answer:

x=-14 is the answer. Hope this helps :)

Answer:

x=-14

Step-by-step explanation:

-x  =14 (multiply by 4)

x = -14 (multiply by -1)

Answer:

each person gets 40 pennies.

Step-by-step explanation:

Hudson AND 7 = 8

320 ÷ 8 = 40

Each person gets 40 pennies.

I hope this helped and if it did I would appreciate it if you marked me Brainliest. Thank you and have a nice day!

Each person gets 40 pennies.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Hudson and 7 of his friends found a bag of pennies.

Total pennies= 320

So, Pennie get by each

=320 ÷ 8

= 40

Hence, Each person gets 40 pennies.
