Answer 1

Answer:

2x+20 + x+40 = 180

Step-by-step explanation:

The angles are supplementary so they add to 180

2x+20 + x+40 = 180

Answer 2

Answer:

( 2 x + 20 )° + ( x +40 )° = 180°

Step-by-step explanation:

They both angles are on straight line so , its supplementary angles and we know that sum of angles of supplementary angle is 180°.

( 2 x + 20 )° + ( x +40 )° = 180°

Which of the following best describes the equation below? 3(x + 9) + 6x = 9x - 27 A. no real solutions B. exactly one real solution, x = -1 C. exactly one real solution, x = D. infinite real solutions

Answers

Answer:

no solutions

Step-by-step explanation:

3(x + 9) + 6x = 9x - 27

Distribute

3x+27 +6x = 9x -27

Combine like terms

9x +27 = 9x -27

Subtract 9x from each side

27 = -27

Answers

Answer:29

Step-by-step explanation:

Opposite angles in a quadrilateral (the trapezium inside the circle) must add up to 180, so 180-92 = 88.

So DAB = 88

Angles on a straight line add up to 180, so to find t, you have to 180 - 88 - 63 =  29

So t is 29.

Solve the following equation for A. Be sure to take into account whether a letter is
capitalized or not.
q2 = g(-h + A)

Answers

Answer:

A = (q² + gh) / g

Step-by-step explanation:

Given equation:

q² = g(-h + A)

Solve for A

q² = g(-h + A)

q² = -gh + gA

Add -gh to both sides

q² + gh = -gh + gA + gh

q² + gh = gA

Divide both sides by g

(q² + gh) / g = gA / g

A = (q² + gh) / g

Ruth is knitting hats to sell at a local fair. The booth costs her $63 and the materials for each hat cost $10. She plans on selling them for $19. How many hats will Ruth have to make to break even, and how much will sales and costs be at that point? ​

Answers

Answer: Ruth have to make 7 hats to break even.

Step-by-step explanation:

Break even point is a point where Cost = Revenue.

Let x be the number of hats sold.

Given: Cost of booth = $63

Each hat cost = $10

Selling price for each cost = $19

As per given,

Total cost = Cost of booth+ (Cost of each hat)(Number of hats)

= 63+10x

Total selling price = 19x

For break even,

63+10x=19x

9x=63

x=7

Hence, Ruth have to make 7 hats to break even.

Consider the figure below, where line a is parallel to line b:

Angle 4 = 12m - 4
Angle 5 = 10m + 20
Calculate the measure of Angle 5.

Answers

Answer:

Angle 5= 140

Step-by-step explanation:

I assume you are talking about parrallel lines and a transversal. If that is the case, I can guess that angles 4 and 5 are alternate exterior angles. Therefore they are congruent.

12m-4=10m+2012m=10m+24     You add 4 to -4 and 202m=24                You subtract 10m from 10m and 12mm=12                    Divide both sides by 210(12)+20             Substitute m for 12 in the equation for Angle 5120+20                Multiply 10 by 12140                      Add 120 and 20

Point J is on line segment \overline{IK} IK . Given IK=5x,IK=5x, IJ=4,IJ=4, and JK=4x,JK=4x, determine the numerical length of \overline{IK}. IK

Answers

Answer:

IK = 20

Step-by-step explanation:

If Point J is on the line segment IK, then;

IK = IJ + JK

Given that

IJ = 4

IK = 5x

JK = 4x

Substitute into the expression

5x = 4 + 4x

5x - 4x  = 4

x = 4

Get the value of IK

IK = 5x

IK = 5(4)

IK = 20

Hence the numerical length of IK is 20
