Explain the steps you use to solve the equation: 2(x-2) =26
Answers
Solution:
Simplify the distributive property and solve.
2(x - 2) = 26=> 2x - 4 = 26=> 2x = 26 + 4=> 2x = 30=> x = 15The solution to the equation is 15.
Your required solution :
Let us solve this equation..!!
Firstly multiplying 2 by (x - 2)
⇒ 2 × (x - 2) = 26
⇒ 2x - 4 = 26
On transposing -4 to R.H.S. it would be positive,
⇒ 2x = 26 + 4
⇒ 2x = 30
On dividing 30 by 2 we gets,
⇒ x = 30/2
⇒ x = 15
Therefore, value of x is 15.

The Gift Basket Store had the following premade gift baskets containing the following combinations in stock. Cookies Mugs Candy Coffee 20 13 10 Tea 12 10 12 Choose 1 basket at random. Find the probability that it contains a. Coffee or candy b. Tea given that it contains mugs c. Tea and cookies
Answers
Using it's concept, it is found that the probabilities are:
a. 0.7143 = 71.43% probability that is contains coffee or candy.
b. 0.4348 = 43.48% probability that it contains tea, given that it contain mugs.
c. 0.1558 = 15.58% probability it contains tea and cookies.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
Item a:
There is a total of 20 + 13 + 10 + 12 + 10 + 12 = 77 baskets, of which 20 + 13 + 10 + 12 = 55 contain coffee or candy, hence:
[tex]p = \frac{55}{77} = 0.7143[/tex]
0.7143 = 71.43% probability that is contains coffee or candy.
Item b:
13 + 10 = 23 contain mugs, of which 10 contain tea, hence:
[tex]p = \frac{10}{23} = 0.4348[/tex]
0.4348 = 43.48% probability that it contains tea, given that it contain mugs.
Item c:
Out of the 77, 12 contain tea and cookies, hence:
[tex]p = \frac{12}{77} = 0.1558[/tex]
0.1558 = 15.58% probability it contains tea and cookies.

1) The sum of the two numbers is 36 and their difference is 9. Find the average of the two numbers.
Answers
Answer:
22.5 and 13.5 are the numbers. average of both numbers is 18.
Step-by-step explanation:
Given that there are two numbers.
let them be, x and y
using the unknown numbers,
x + y = 36x - y = 9make x the subject:
x + y = 36x = 36 - y ..........equation 1 x - y = 9x = 9 + y ..........equation 2Solve them simultaneously:
9 + y = 36 - yy + y = 36 - 92y = 27y = 13.5Then another number, x:
x = 9 + yx = 9 + 13.5x =22.5Average:
( sum of both the numbers ) ÷ 2( 22.5 + 13.5 ) ÷ 218
Let the two numbers be x and y
x+y = 36 -----(1)
x - y = = 9-----(2)
(1)+(2)
x +y = 36
x - y = 9
---------------
2x = 45
x = 45/2
Then y =?
x - y =9
45/2 - y =9
y = 45/2-9
y = (45-18)/2
y = 27/2
The two numbers are 45/2 and 27/2

Find the lettered angles.
Answers
Answer:
a) ∠a = 72°
∠b = 108°
b) ∠[tex]x[/tex] = 56°
c) ∠m = 95°
Step-by-step explanation:
Sum of interior angles of a polygon = (n − 2) × 180(where n is the number of sides)
If the side of a polygon is extended, the angle formed outside the polygon is the exterior angle.
The sum of the exterior angles of a polygon = 360°
The sum of angles on a straight line = 180°
a) This shape is a regular polygon with 5 sides.
Therefore, sum of the interior angles = (5 - 2) x 180 = 540°
Therefore, ∠b = 540 ÷ 5 = 108°
∠a = 180 - 108 = 72°
b) The sum of the exterior angles of a polygon = 360°
Therefore, 55 + 63 + 52 + 44 + 90 + [tex]x[/tex] = 360
304 + [tex]x[/tex] = 360
[tex]x[/tex] = 360 - 304 = 56°
c) The sum of the exterior angles of a polygon = 360°
Therefore, 40 + 40 + 35 + 40 + 50 + 60 + m = 360
265 + m = 360
m = 360 - 265 = 95

It can help to start by writing the similarity statement for each figure. To do that, you can identify corresponding features, then work around the figure in a direction that maintains the correspondence of the vertices. Here the figures are dilated, and problem 5 has the figure rotated. Since there is no reflection involved, the corresponding vertices remain in clockwise order.
Once you have written the similarity statement, you can identify the values given for corresponding parts. Here, the values are all for side lengths (not angles). Corresponding sides will have their vertices in the same relative position in the similarity statement.
5.Working counterclockwise from the acute angle, we have ...
KNML ~ PSRQ
Then corresponding sides are ...
KN = 7x -9 . . . . PS = 60
NM = not given . . . . SR = not given
ML = 4x +4 . . . . RQ = 48
LK = not given . . . . QP = not given
Now, you can write a proportion that involves corresponding sides. The main point here is to put corresponding parts in the same relative locations in the proportion. We can write this a couple of ways:
KN/ML = PS/RQ ⇔ (7x -9)/(4x +4) = 60/48
or
KN/PS = ML/RQ ⇔ (7x -9)/60 = (4x +4)/48
We note here that solution is generally easier if the variable is put in the numerator of the expression. We might choose the latter form for that reason. We might choose the first form because we know we can reduce the fraction 60/48 to 5/4, simplifying the problem a bit.
Using the second form of the proportion, we can solve it as follows:
(7x -9)/60 = (4x +4)/48
4(7x -9) = 5(4x +4) . . . . . . multiply by the LCM of 60 and 48, which is 240
28x -36 = 20x +20 . . . . . eliminate parentheses
8x = 56 . . . . . . . . . . . add 36-20x to both sides
x = 7 . . . . . . . . . divide by 8
__
6.Counterclockwise from S, the similarity statement can be written ...
ΔSYZ ~ ΔSRT
Corresponding parts are ...
SY = not given . . . . SR = not given
YZ = 2x +2 . . . . RT = 3x -7
ZS = 40-5 = 35 . . . . TS = 40
A suitable proportion is ...
(2x +2)/35 = (3x -7)/40
8(2x +2) = 7(3x -7) . . . . . . . . multiply by 280
16x +16 = 21x -49 . . . . . . eliminate parentheses
65 = 5x . . . . . . . . . add 49-16x to both sides
x = 13 . . . . . . . divide by 5
YZ = 2x +2 = 2(13) +2
YZ = 28
