How do I solve for x

Answer:

x=7

Step-by-step explanation:

6x+8+7x-9=90

13x+8-9=90

13x-1=90

add 1 to both sides

= 13x=91

divide both sides by 13

= x=7

Answer:

B

Step-by-step explanation:

By applying basic formula of probability we got that statement  "The probability of randomly selecting a green or a black button from Package L is equal to the probability of randomly selecting a red button from Package M." is True

Probability means chances of  an event to occur .

Probability = favourable outcome /the total number of possible outcomes.

Total button in package L= 50

Total button in package M= 30

(a)

Probability of selecting green or black button from package L= (8+7)/50

=15/50=3/10

Probability of selecting red  button from package M=9/30 = 3/10

Hence statement is true

(b)

Probability of selecting black button from package L= 7/50

Probability of selecting black button from package L=8/50

Hence statement is false

(c)

Probability of selecting red button from package L=12/50=6/25

Probability of selecting green button from package M=6/30=1/5

Hence statement is false

(d) Probability of selecting yellow button from package L=10/50=1/5

Probability of selecting yellow or green button from package M=9/30=3/10

Hence statement is false .

By applying basic formula of probability we got that statement  "The probability of randomly selecting a green or a black button from Package L is equal to the probability of randomly selecting a red button from Package M." is True .

Answer: 5 and 12

Step-by-step explanation:

2 and 12 is not it   because 12 can be divided by 2 meaning that the LCM of those two numbers will be 12.

6 and 12 is not it because  12 can also be divided  by 6 meaning that the LCM of 6 and 12 is also 12.

3 and 12 is also the same,  12  can be divided by 3 so their LCM will be 12.

With 5 and 12, 12 is not divisible by 5 so  you will have to find the multiples of 5 and 12 and it will eventually be 60.

Multiples of 5:  5, 10,15,20,25,30,35,40,45,50,55,60,65

Multiples of 12:  12, 24, 36, 48, 60, 72  

As it appears in both multiples, 60 is the least number that appears in both multiples so the LCM of 5 and 12 is 60.

Answer:   $14.02

Step-by-step explanation:

Marked down by 45% means it will have a 45% percent discount.

Subtract 45% from 100%  then multiply it by the amount .

100% - 45% = 55%

55% * 25.49 =  14.0195  Round it to the nearest hundredth to convert it to money.

NL = 20 units

Step-by-step explanation:

Property of a rectangle,

"Diagonals of a rectangle are equal in measure and divide each other in two equal parts"

By using this property,

PT = TL

(x + 3) = (3x - 11)

3x - x = 11 + 3

2x = 14

x = 7

Length of PT = (x + 3) = 10

Length pf PA = 2(PT) = 20 units

Length of NL = PA = 20 units

Answer:

40 degrees

Step-by-step explanation:

360/9=40

The solution is 40°

The measure of one exterior angle of a nonagon is is given by the equation A = 360°/9 and the measure of A is 40°

What is the sum of an exterior angle of a polygon?

The sum of exterior angles in a polygon is always equal to 360 degrees. Therefore, for all equiangular polygons, the measure of one exterior angle is equal to 360 divided by the number of sides in the polygon. The sum of an interior angle and its corresponding exterior angle is always 180 degrees since they lie on the same straight line

Sum of exterior angles of a polygon = 360°

Measure of each exterior angle = 360° / N

where N is the number of sides

Given data ,

Let the measure of each exterior angle be = A

Let the number of sides of the polygon be = N

Now , the polygon is a nonagon

So , the number of sides N = 9

Now , The sum of exterior angles of a polygon is 360°

So ,

The measure of each exterior angle is given by the equation  360° / N where N is the number of sides

Substitute the value for N in the equation , we get

The measure of each exterior angle = 360°/9

The measure of each exterior angle = 40°

Therefore , the value of A is 40°

Hence , the measure of each exterior angle is 40°

Answer: Interior angles at Jamestown and Yorktown are 40° and 20°, respectively

Step-by-step explanation: Jamestown, Williamsburg and Yorktown form a triangle. The sum of the interior angles of a triangle is 180°.

Suppose interior angle at Yorktown is x. As Jamestown is twice the measure at Yorktown, it means this interior angle is 2x.

Then, the measures will be:

2x + x + 120 = 180

3x = 60

x = 20

Angle at Yorktown is 20°.

So, angle at Jamestown is

2x = 2.20 = 40°

The measures of the interior angles at Jamestown and Yorktown are 40° and 20°, respectively.

Answer:

15.4%

Step-by-step explanation:

Calculate the volume of both containers.

The volume (V) of a cylinder is calculated as

V = πr²h ( r is the radius and h the height )

[tex]V_{A}[/tex] = π × 10² × 11 = 1100π ft³

[tex]V_{B}[/tex] = π × 7² × 19 = 931π ft³

Subtract volume of B from volume of A to find quantity left in A

quantity left in A = 1100π - 931π = 169π ft³

To calculate the percentage left in A after B has been filled

[tex]\frac{left}{full}[/tex] × 100%

= [tex]\frac{169\pi }{1100\pi }[/tex] × 100%

= [tex]\frac{169}{1100}[/tex] × 100%

= 15.4% ( to the nearest tenth )

The correct statements are:

In a paragraph proof, statements and their justifications are written in sentences in a logical order.

A two-column proof consists of a list of statements and the reasons the statements are true.

A flowchart proof is a visual way of describing the statements and reasons for a proof.

A flowchart is a graphical representation of a process, algorithm, or system that uses symbols, shapes, and arrows to depict the various steps and their interconnections.

We have,

In a two-column proof, each statement is listed in one column, and the justification for the statement is listed in a separate column.

A flowchart proof also provides a visual representation of the sequence of steps, but it includes justifications for each step.

So,

The following statements are incorrect:

A flowchart proof gives a visual representation of the sequence of steps without justifications.

A two-column proof lists only the given information and what is to be proven.
