The Perimeter of a Pentagon is 20.5 centimeters. Four sides of this pentagon have the same length, in centimeters, x, and the other side has a length of 2.1 centimeters, as shown below. What is the value of x?
Answer:
[tex]4.6\ \text{cm}[/tex]
Step-by-step explanation:
Perimeter of the pentagon = 20.5 cm
Length of 4 sides = [tex]x[/tex]
Length of the other side = 2.1 cm
Perimeter of the pentagon will be
[tex]x+x+x+x+2.1=20.5\\\Rightarrow 4x+2.1=20.5\\\Rightarrow 4x=20.5-2.1\\\Rightarrow 4x=18.4\\\Rightarrow x=\dfrac{18.4}{4}\\\Rightarrow x=4.6\ \text{cm}[/tex]
The value of [tex]x[/tex] is [tex]4.6\ \text{cm}[/tex].

helppp i don’t know how to find where the lines will intercept
Answer:
(-5,10)
Step-by-step explanation:
You need to do this by finding a point where it is a solution to both equations. You can do this by using systems of equations.
y=25+3x
y=-5-3x
subtracting, you get 0=30+6x
simply, -30=6x, x=-5.
you're half way done! now plug in x in one of the equations to get the y value.
-5*3+25 = y = 10

Answer:
y=−8x+53
Step-by-step explanation:
I think... I'm not sure so I'm sorry if its wrong
Answer: Here is an explanation of how to get the answer.
Step-by-step explanation:
It tells you the slope is -8, so you know your equation will look like this:
y = -8x + b,
where b is the intercept. You also are given a point that is on the line, so that is an x and a y value that are a solution to the equation. You can plug those in and solve for b.
5 = -8(6) + b
53 = b
So, your equation is y = -8x + 53
Write the equation of the line fully simplified slope-intercept form
Answer:
y=mx+b
Step-by-step explanation:
standard slope intercept form. just plug in slope and intercept

What is the value of the expression -8×3.4 ?
Answer:
-27.2
Step-by-step explanation:
what is greater than 1/2 what fractions are greater than 1/2
Answer:
3/4
Step-by-step explanation:
3/4 is one example of a fraction that is greater than 1/2. If 1/2 become 2/4, therefore 3/4 is a fraction which is greater than 1/2.
A sailboat begins a voyage with 145 lb of food. The
crew plans to eat a total of 15 lb of food per day. The crew plans to have 25 lb
of food remaining when they end their voyage. How many days does the crew
expect their voyage to last?
Answer:
The crew expects their voyage to last 8 days.
Step-by-step explanation:
There are initially 145 lb of food in the sailboat.
The crew plans to eat 15 lb of food per day, and they want to leave 25 lb of food remaining when they end the voyage.
The amount of food to eat during the voyage is 145 - 25 = 120 lb.
Since the daily consumption of food is 15 lb, there is enough food for 120/15 = 8 days.
The crew expects their voyage to last 8 days.

What is 3/16= c-7/8 please answer
Answer:
c=17/16
Step-by-step explanation:
3/16=c-7/8
find the common denominator
3/16=c-14/16
add 14/16 on both sides to cancel
c=17/16
Answer:
c= 17/16
Step-by-step explanation:
move 7/8 to the right so cancel it out by adding which would add with 3/16 giving 17/16 = c

Step-by-step explanation:
what is the slope of a line parallel to the line y=3x-4=8y+1
Answer: If the original equation is y = 3x -4, the slope is 3.
Any equation of a line parallel to the line y = 3x -4 will have a slope of 3.
Step-by-step explanation:
In slope-intercept form, y =mx + b the coefficient of x, m is the slope.
Here 3 is that value.
It is very unusual to have two equal signs in a question about slope.
I am not sure what to do with the =8y + 1

Beth plays a video game in which she starts with 0 points. In round 1, she losses 31/2 points in round 2, she wins 281/2 points ,and in round 3, she losses another 3 1/2 points .What is her final score?
Answer:
[tex]21\frac{1}{2} \ or\ 21.5[/tex]
Step-by-step explanation:
Given that:
Initial score of Beth = 0
Round 1 scores:
Points lost = [tex]3\frac{1}{2} = 3.5[/tex]
Round 2 scores:
Points won = [tex]28\frac{1}{2}=28.5[/tex]
Round 3 scores:
Points lost = [tex]3\frac{1}{2} = 3.5[/tex]
To find:
The final score of Beth in the video game = ?
Solution:
Let us calculate the total points lost and total points won by Beth in the video game.
Then we will subtract the total points lost from the total points won to find the final score in the video game.
Total points won = 28.5
Total points lost = 3.5 + 3.5 = 7
So, final score = Total points won - Total points lost
Final score = 28.5 - 7 = 21.5 or [tex]\bold{21\frac{1}{2}}[/tex]

Can someone pls help
Answer:
x=10
Step-by-step explanation:
3x+10=6x-20 Set the angles equal to each other b/c they are alt. int. angles.
-3x -3x Subtract by 3x on both sides to get x by itself
----------------
+10 =3x-20
+20 +20 Add 20 to both sides to get x by itself
---------------------
30 =3x
/3 /3 Divide both sides by 3 to get x by itself
-------------
10 =x
x=10 Write x first.
