he pentagon has five sides as shown in the figure. The perimeter can be expressed as 5 + 5 + 2 x + x + 2 x.
A pentagon with side lengths of 5, 5, 2 x, 2 x, and x.
Which expression is equivalent to the perimeter expression?
5 + 4 x
10 + 4
5 + 5 x
10 + 5 x
Answer:
10+5x
Step-by-step explanation:
To find the perimeter, let's add up all the sides and combine like terms.
5 + 5 + 2x + 2x + x
Adding 5 and 5 gets us 10, and adding 2x, 2x, and x gets us 5x.
So, the perimeter should be 10 + 5x, or D
What is the closest integer to 190?
Answer:
When a number is halfway between the two possible numbers, round up to the greater number. Since 186 is between 180 and 190, and 186 is closer to 190, you round up to 190. You can use a number line to help you round numbers.

“ a number increases by thirty-five “ (translating expressions)
Answer:
n + 35
Step-by-step explanation:
Let's convert the words to math:
"a number" we can define as n.
"increases" we can define as addition, or sum (+).
"thirty-five" we can define as 35.
We then combine all the translations:
n + 35

One person takes up about 2.5 square feet of space. Use this value to estimate how many people can fit in an area that is 120 feet wide and 300 feet long.
9514 1404 393
Answer:
14,400 people
Step-by-step explanation:
The area is the product of length and width:
A = LW
A = (300 ft)(120 ft) = 36,000 ft^2
Then the number of people is the area divided by the area per person:
(36,000 ft^2)/(2.5 ft^2/person) = 14,400 persons

This week we worked on inequalities with two variables. We used graphing to show what the inequalities looked like.
Question # 1: Describe a test you can use to see if a coordinate pair is the solution to an inequality using its graph.
Question #2: Which kind of line ( solid or dashed) is used for ?
Question #3: Now that we can graph an inequality in two variables>>> What do you think we will be trying to learn next week ?
Answer:
1. you have to describe a test so just tell of a test you took that was about graphing and has the symbols <, ≤, ≥, >
2. > or < is dashed line
≥ or ≤ is solid line
3. what do you think?

Find an equation of the line passing through each of the following pairs of points (−3, 1), (0, 3)
Answer:
y = 2/3x + 3
Step-by-step explanation:
Use rise over run (y2 - y1) / (x2 - x1)
Plug in the points:
(3 - 1) / (0 + 3)
= 2/3
So, the slope is 2/3
Plug this and another point into y = mx + b to find b:
y = mx + b
3 = 2/3(0) + b
3 = b
Then, plug b and the slope into y = mx + b
y = 2/3x + 3 is the equation of the line

Find the slope and the y-intercept of the line.
y=7x-4. slope: ? y-intercept: ?
Answer:
Slope: [tex]\boxed {7}[/tex]
Y-intercept: [tex]\boxed {-4}[/tex]
Step-by-step explanation:
About the Slope-Intercept Form equation, the variable [tex]m[/tex] is the slope and variable [tex]b[/tex] is the y-intercept. So, according to the following expression, the slope would be [tex]7[/tex] and the y-intercept would be [tex]-4[/tex]:
-Slope-Intercept Equation:
[tex]y = mx + b[/tex]
Slope: [tex]m[/tex]
Y-intercept: [tex]b[/tex]
-The following expression:
[tex]y = 7x - 4[/tex]
Slope: [tex]\boxed {7}[/tex]
Y-intercept: [tex]\boxed {-4}[/tex]

1.Use the midpoint formula to find the midpoint of AB¯¯¯¯¯¯¯¯ and CD¯¯¯¯¯¯¯¯. Show that the midpoint of these two sides has the same x-coordinate. Then, show that the midpoint of BD¯¯¯¯¯¯¯¯ and AC¯¯¯¯¯¯¯¯ has the same y-coordinate. Thus, the quadrilateral is a parallelogram.
2.Use the midpoint formula to find the midpoint of AD¯¯¯¯¯¯¯¯ and BC¯¯¯¯¯¯¯¯. Show that the midpoint for both segments is the same. Since the diagonals of a quadrilateral intersect each other, then the quadrilateral is a parallelogram.
Use the midpoint formula to find the midpoint of line segment cap A cap d and Show that the midpoint for both segments is the same. Since the diagonals of a quadrilateral intersect each other, then the quadrilateral is a parallelogram.
3.Use the midpoint formula to find the midpoint of line segment cap A cap d and Show that the midpoint for both segments is the same. By the definition of midpoint and bisect, line segment cap A cap d and line segment cap b cap c bisect each other. Since the diagonals of a quadrilateral bisect each other, then the quadrilateral is a parallelogram.
4.Use the midpoint formula to find the midpoint of AB¯¯¯¯¯¯¯¯ and CD¯¯¯¯¯¯¯¯. Show that the midpoint for both segments is the same. Since opposite sides of a quadrilateral have the same midpoint, then the quadrilateral is a parallelogram.

The distance from the center of a circular tent to the tent’s edge is 50 feet. Kelly walked around the edge of the tent twice and then straight to the center of the tent. About how far did Kelly walk?
Answer:
678.32 feet
Step-by-step explanation:
Circumference=2π(radius)=2·π·50≈314.15927
314.15927·2=628.31854
628.31854+50=678.31854
Answer:
678 ft (nearest foot)
Step-by-step explanation:
The distance from the center of a circle its edge is its radius.
Given that the distance from the center of a circular tent to the tent’s edge is 50 ft then:
⇒ radius (r) = 50
The edge of a circle is its circumference
Circumference of a circle = [tex]2\pi r[/tex] (where r is the radius)
Therefore, the circumference of the tent is:
[tex]\implies 2 \cdot \pi \cdot 50=100\pi[/tex] ft
If Kelly walked around the edge of the tent twice, then walked straight to the center:
⇒ total distance walked = 2 × circumference + radius
= 2 × [tex]100\pi[/tex] + 50
= 678.3185307...
= 678 ft (nearest foot)
Find the slope (15 points)
Answer:
-5/3
Step-by-step explanation:
We pick two points on the line
(0,4) and ( 3, -1)
Then use the slope formula
m = ( y2-y1)/ (x2-x1)
= ( -1-4)/(3-0)
= -5/3
Answer: -5/3
Step-by-step explanation: The function follows the slope of rise 5 units, run 3.
A coach is buying snacks for 22 players at a soccer match. She pays a total of $77 to
buy each player a bottle of water and an energy bar. The price of one energy bar is $2.
Which quantity is unknown?
A. the total amount paid
B. the number of players
C. the price of a bottle of water
D. the price of an energy bar
Answer: C the price of a water bottle
Step-by-step explanation: The problem states that the energy bar is $2 so it can’t be D. The math problem also states how many players they have so it’s not B. The math problem says how much they paid which is $77 so it’s not A. However the problem doesn’t state how much the price of a water bottle is so therefore it is C.

Answer: How many pets does Alisha have at home?
Step-by-step explanation:
A statistical question, put simply, is something based on facts and numbers. The only option here that is not an opinion is the first option, "How many pets does Alisha have at home?"
Two of the other options have something to do with a bias or an opinion. This is stuff such as "your favorite" or "do you like." The last one has to do with a name, not a number.
