Answer:
x = 5
Step-by-step explanation:
I'm assuming the question is asking to solve for variable x.
The two red arrows signify the two lines are congruent, meaning they equal the same measurement.
In other words:
23x - 5 = 21x + 5
Isolate the variable x
Add 5 to both sides to cancel 5 from the left side
23x - 5 + 5 = 21x + 5 + 5
23x + 0 = 21x + 10
23x = 21x + 10
Subtract 21x from both sides to cancel 21x from the right side
23x - 21x = 21x - 21x + 10
2x = 0x + 10
2x = 10
Divide both sides by 2 to isolate the variable x
2x ÷ 2 = 10 ÷ 2
x = 5
When solving for these types of problems, always isolate the variable. Also, keep in mind that whatever you do to one side, you must do to the other (such as how I added 5 to both sides).

The scatter plot shows a hiker's elevation above sea level over time. The equation of the trend line shown is y = 8.77x + 686. To the nearest whole number, predict what the hiker's elevation after 145 minutes
Answers
Answer:
707 feet above sea level
Step-by-step explanation:
2 hours and 25 minutes is about 2.4167 hours.
Therefore:
y=8.77x+686
y=8.77(2.4167)+686
y=21.1944+686
y=707.1944
So the hiker's elevation will be approximately 707 feet above sea level

Example: Solve this triangle
right angled triangle 5 12 c
Start with: a2 + b2 = c2
Put in what we know: 52 + 122 = c2
Calculate squares: 25 + 144 = c2
25+144=169: 169 = c2
Swap sides: c2 = 169
Square root of both sides: c = √169
Calculate: c = 13
A group of 53 tourists visit a museum. Museum volunteers lead tours for groups of no more than 8 tourists. Draw a model to show the least number of groups that can be formed for these 53 tourists. Use circles to show the groups and choose a symbol to show each person.
Answers
Answer:
Total number of group formed = 7
Step-by-step explanation:
As given,
1 group has 8 people
Total people = 53
Let
Total number of group made = x
As 1 group = 8 tourist
⇒x group = 8x tourist
As Total tourist = 53
⇒8x = 53
⇒x = [tex]\frac{53}{8}[/tex] = 6.6
This means,
There are 6 full group of 8 people in each group = 48 tourist
and 1 group of 53-48 = 5 people.
So,
Total number of group formed = 7

A person on a moving sidewalk travels 24feet the in 7 seconds. The moving side walk has a length of 180 feet. How long will it take to move from one end to the other?
Answers
Given:
A person on a moving sidewalk travels 24 feet the in 7 seconds.
The moving side walk has a length of 180 feet.
To find:
Time taken by the person to move from one end to the other.
Solution:
A person on a moving sidewalk travels 24feet the in 7 seconds.
The speed of the person is
[tex]\text{Speed}=\dfrac{\text{Distance}}{\text{Time}}[/tex]
[tex]\text{Speed}=\dfrac{24}{7}[/tex]
[tex]\text{Speed}=\dfrac{24}{7}[/tex]
The moving side walk has a length of 180 feet.
[tex]\text{Time}=\dfrac{\text{Distance}}{\text{Speed}}[/tex]
[tex]\text{Time}=\dfrac{180}{\dfrac{24}{7}}[/tex]
[tex]\text{Time}=\dfrac{180}{1}\times \dfrac{7}{24}[/tex]
[tex]\text{Time}=52.5[/tex]
Therefore, the time taken by the person to move from one end to the other is 52.5 seconds.

3a + 3c = 40.50
What values of a and c represent the solution to the system?
a =
c =
Answers
Answer:
a=8
c=5.5
Step-by-step explanation:
solve simultaneously:
2a + 4c = 38.00
3a + 3c = 40.50
times the first eq. by 3 and the second by 2
6a + 12c = 114
6a +6c = 81
subtract from one another
6a + 12c = 114
-6a +6c = 81
6c = 33
c=5.5
3a + 3x5.5 = 40.50
3a= 24

A point R (-2,5) is mapped to point R',as described by a translation of 6 units to the rights and 7 units down.Mark R' on the coordinate plane.
Answers
Answer:
(4, -2)
Step-by-step explanation:
Given a point R (-2,5), if the point R' is described by a translation of 6 units to the rights and 7 units down, then the coordinate of R' will be;
6 units to the rights is towards the positive x axis
7 units down is towards the negative y axis
R' = (-2+6, 5-7)
R' = (4, -2)
Hence the coordinate point of R' on the plane is (4, -2)

The fabric cost 7cents per square inch. She will only pay for the fabric used to cover the box, even if there is waste or extra. How much money did shyla spend on fabric? Is the box is 7 by 11by 8 inchs
Answers
Answer:
Shyla will pay about 63 cents to cover the box
Step-by-step explanation:
Length of the box ( l ) = 7 inches
Width of the box (b) = 11 inches
Height of the box (h) = 8 inches
We can solve this equation by following two simple steps.
1. The first step is to find the total surface area of the box. This is the total area that the decorative fabric will be covering.
We can get this by the following formula:
SA=2( length X width) +2( length X height )+2(height X width)
SA = 2( 7 X 11 ) + 2(7 X 8) + 2 (8 X 11 ) = 442 square inches
2. The second step is to divide the total surface area by the price of the fabric per square inch.
This will be 442 square inches divided by 7 cents per square inch = 63.14 cents
Shyla will pay about 63 cents to cover the box

The length of a rectangle is six times its width.
If the perimeter of the rectangle is 84 ft, find its area.
Answers
The area of the rectangle is 216 square feet
How to determine the area?Let x represents the length and y represents the width.
So, we have:
x = 6y
So, the perimeter is:
P = 2(x + y)
The perimeter is given as:
P = 84
So, we have:
2(x + y) = 84
Divide by 2
x + y = 42
Substitute x = 6y in x + y = 42
6y + y = 42
Evaluate the sum
7y = 42
Divide by 7
y = 6
Substitute y = 6 in x = 6y
x = 6 * 6
x = 36
The area is calculated as:
Area = xy
So, we have:
Area = 36 * 6
Evaluate
Area = 216
Hence, the area of the rectangle is 216 square feet
