Part B.

Describe two different ways you could find measure of CFD. What is the measure of

this angle?

Answers

Answer 1

Answer:

∠CFD = 60°

Step-by-step explanation:

Along line CE:

∠AFE + ∠AFB + ∠BFC = 180° (sum of angles on a straight line)

(7x + 4) + (8x + 6) + (6x + 2) = 180

collecting alike terms:

7x + 8x + 6x + 4 + 6 + 2 = 180

21x + 12 = 180

21x = 168

x = 8°

We could find the  measure of CFD using:

a) Along line AD:

∠AFB + ∠BFC + ∠CFD = 180° (sum of angles on a straight line).

(8x + 6) + (6x + 2) + ∠CFD = 180

14x + 8 + ∠CFD = 180

∠CFD = `180 - (14x + 8)

∠CFD = 172 - 14x

b) ∠CFD = ∠AFE (vertical opposite angles are equal)

∠CFD = 7x + 4

To find value of ∠CFD, substitute x = 8

∠CFD = 7(8) + 4

∠CFD = 60°

A company has 64 employees of whom x are members of a union. How many employees are not union members?

Answers

Answer:

To find the number of members that are not part of the union, we take the total number of workers (64) and subtract it with the number of workers that are in a union (x). So because of this, the answer is:

64 - x

Which statement is true?
x = 157, because 180 - 23 = 157
x = 33, because 180 - (124 + 23) = 33
x = 56, because 180 - 124 = 56
x = 147, because 23 + 124 = 147

This is called system of innequalities

we know y= 3-x and we substitute that into 2x+y=6 and we get

2x+3-x=6 we solve and get x=3

then we substitute x into the first equation and we get y=3-3 and get 0

A linear inequality is an inequality that involves a linear function.

Examples of linear inequality are: 2x + y < 5, x + y > 2, y - x

A linear equation is represented as:

[tex]\mathbf{y = mx + b}[/tex]

A linear inequality can be gotten from a linear equation by changing the equality sign to any of the following inequality sign: >, < !=, >= and <=

So, examples of linear inequality are:

2x + y < 5, x + y > 2, y - x >= 2, 12x + 4y <= 20 and 6y - 7x > 1

On Monday you sent x number of text messages. On Tuesday you sent twice as many. On Wednesday you sent 12 more texts than you sent on Tuesday. On Thursday you sent half as many as you sent on Wednesday. Which expression represents the number of text messages you sent on Tuesday? Which expression represents the number of text messages you sent on Wednesday? Which expression represents the number of text messages you sent on Thursday?

Answers

Answer: Expression represents the number of text messages you sent on Tuesday = 2x

Expression represents the number of text messages you sent on Wednesday = 12+2x

Expression represents the number of text messages you sent on Thursday = x+6

Step-by-step explanation:

Given:

Number of text messages sent on Monday = x

On Tuesday, Number of text messages sent  = 2 (Number of messages sent on Monday)

= 2 x

On Wednesday, Number of text messages sent  = 12+ (Number of messages sent on Tuesday)

= 12 +2x

On Thursday, Number of text messages sent  = [tex]\dfrac12(2x+12)[/tex]

= x+6

Expression represents the number of text messages you sent on Tuesday = 2x

Expression represents the number of text messages you sent on Wednesday = 12+2x

Expression represents the number of text messages you sent on Thursday = x+6

On Monday you sent x number of text messages. On Tuesday you sent twice as many. On Wednesday you sent 12 more texts than you sent on Tuesday. On Thursday you sent half as many as you sent on Wednesday.

A recipe calls for 3 cups of pecans for every 5 cups of walnuts. How many cups of pecans should be added to 8 cups of walnuts?
A. 1.3 cups
B. 1.875 cups
C. 4.8 cups
D. 15 cups

Answers

Answer:A

Step-by-step explanation:

A ratio shows us the number of times a number contains another number. The correct option is C.

What is a Ratio?

A ratio shows us the number of times a number contains another number.

Given that a recipe calls for 3 cups of pecans for every 5 cups of walnuts. Therefore, the ratio of pecans to walnuts is,

Pecans/ Walnuts = 3 cups / 5 cups

Now, the number of cups of pecans that should be added to 8 cups of walnuts is,

Pecans/ Walnuts = 3 cups / 5 cups

Pecans/ 8 cups = 3 cups / 5 cups

Pecans = (8×3)/5 cups

Pecans = 4.8 cups

Hence, the correct option is C.

Angle ABF is 120°.

Step-by-step explanation:

Vertical angles are used to get the measure of angle ABG (3x) and FBE (2x) and all of those added together are 180. Then you use PEMDAS to get x. Then you find ABF by multiplying 3 by 30 (what you get when you use PEMDAS to find x) then you add 30 to that and you get 120.
