Answer:
30f + 20
Step-by-step explanation:
A square has four sides, all of equal length. If we call that side length x, then the perimeter - the total length around the square - is 4x. To find the side length given the perimeter then, we can simply divide the perimeter by 4.
Our perimeter here is 120f + 80, and dividing each term by 4 gives us a side length of 30f + 20.
Last night, 4 friends split the dinner bill evenly. Each friend paid $12.75 and left the same amount for a tip. The bills total was $61. What equation could describe the situation?
Answer: 4 * (12.75 + x) = 61
Step-by-step explanation:
Each of the 4 friends paid $12.75 so that is:
= 4 * 12.75
Assuming the tip is denoted as x it would be:
= 4x
Putting them together is:
4 * (12.75 + x) = 61
Solving the equation would give:
4 * (12.75 + x) = 61
51 + 4x = 61
4x = 61 - 51
x = 10/4
x = $2.50
factories:
x(x+1)-y(y+1)
Answer:
[tex](x - y)(x + y + 1)[/tex]
Step-by-step explanation:
[tex]x(x + 1) - y(y + 1)[/tex]
Lets expand it.
[tex] = > {x}^{2} + x - {y}^{2} - y[/tex]
Lets re-arrange it.
[tex] = > {x}^{2} - {y}^{2} + x - y[/tex]
[tex] = > (x + y)(x - y) + 1(x - y)[/tex]
Lets take (x - y) common.
[tex] = > (x - y)[(x + y) + 1] [/tex]
[tex] = > (x - y)(x + y + 1)[/tex]
(x-y)(x+y+1)
Step-by-step explanation:

Which company charges more per hour? Explain.
Answer:
Green Lawns is more expensive
Step-by-step explanation:
Take the hours provided in the table and place them into the function
y=10x + 15
Then compare to Green Lawns.
For 2 hours:
y = 10 * 2 + 15 = $35 / hr
For 3 hours:
y=10 * 3 + 15 = $45 / hr
What is an equation of the line that passes through the points (-6, -3) and
(-3, -5)?
Answer:
y = − 2 /3 x − 7
Step-by-step explanation:
Use the slope formula and slope-intercept form y = m x + b to find the equation.
❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤
Hey buddy ....
I really appreciate God to give me this chance to help u.
Let's see what to do...
-----------------------------------------------------------
First we need to find the slope of the line using this equation :
Suppose a = ( - 6 , - 3 ) , b = ( - 3 , - 5 )
[tex]slope = m = \frac{y(b) - y(a)}{x(b) - x(a)} \\ [/tex]
Just need to put the coordinates in the equation:
[tex]slope = \frac{ - 5 - ( - 3)}{ - 3 - ( - 6)} \\ [/tex]
[tex]slope = \frac{ - 5 + 3}{ - 3 + 6} \\ [/tex]
[tex]slope = \frac{ - 2}{ - 3} \\ [/tex]
[tex]slope = \frac{3}{2} \\ [/tex]
====================================
We have this equation as the point-slope form of the linear functions :
[tex]y - y(one \: \: of \: \: the \: \: given \: \: points) = (slope) \times ( \: x - x(o \: o \: f \: t \: g \: p) \: ) \\ [/tex]
Now just need to put the slope and one the given points ( a or b ) in the above equation:
I like to use a ( you can use b bro )
[tex]y - ( - 3) = \frac{3}{2} \times (x - ( - 6) \: ) \\ [/tex]
[tex]y + 3 = \frac{3}{2} \times (x + 6) \\ [/tex]
[tex]y + 3 = \frac{3}{2} x + 9 \\ [/tex]
Subtract sides 3
[tex]y + 3 - 3 = \frac{3}{2} x + 9 - 3 \\ [/tex]
[tex]y = \frac{3}{2} x + 6 \\ [/tex]
And this is the equation of the line.
So we're done.....

A sum of money is to be divided among three girls, Anna, Barbara and Chrissy in the ratio 5 : 3 : 2. If Barbara received $400 less than Anna, calculate the amount of money each girl received.
Answer:
Anna received $1000
Barbara received $600
Chrissy received $400
Step-by-step explanation:
Let us solve the problem
∵ The ratio of Anna, Barbara, and Chrissy is 5: 3: 2
∵ Barbara received $400 less than Anna
→ That means Anna - Barbara is 400, find the difference between their ratio
∵ The difference between their ratio = 5 - 3 = 2
→ By using the ratio method
→ Anna : Barbara : difference
→ 5 : 3 : 2
→ A : B : 400
→ By using the cross multiplication
∵ A × 2 = 5 × 400
∴ 2A = 2000
→ Divide both sides by 2
∴ A = 1000
∴ Anna received $1000
∵ B × 2 = 3 × 400
∴ 2B = 1200
→ Divide both sides by 2
∴ B = 600
∴ Barbara received $600
Let us use the ratio between Anna and Chrissy to find the amount of Chrissy
→ Anna : Chrissy
→ 5 : 2
→ 1000 : C
→ By using cross multiplication
∵ 5 × C = 2 × 1000
∴ 5C = 2000
→ Divide both sides by 5
∴ C = 400
∴ Chrissy received $400

Solve for x...............
Answer:
x=26
Step-by-step explanation:
let take the 3rd angle of the triangle y
2x + 76 + y = 180 ( angle sum property)
y = 180 ‐ 76 ‐ 2x
y = 104 ‐ 2x
5x ‐ 2 + y = 180 ( linear pair)
5x‐2+104‐2x = 180 ( y = 104 ‐ 2x)
3x+102=180
3x=180‐102
x=78/3
x=26

In a drawer, a dentist keeps 11 mint, 4 grape, and 5 orange flavored toothpastes, What is the theoretical probability of randomly selecting a grape toothpaste?
Answer:
The probability of randomly selecting a grape toothpaste is 4:20.
Step-by-step explanation:
I hope this helps and I hope u have an Amazing Day!
Answer:
The theoretical probability of selecting a grape toothpaste is 4/20.
Step-by-step explanation:
There are 20 toothpastes in total, you want to find out about the grape. The chances of you picking grape is out of 20, so it's 4/20 since there's only 4 grape.

Please help me with #3!!
Solve for x in the figure below
33
2x + 30
41
Given:
An exterior angle of a triangle = 2x+30°
Two opposite interior angles are 33° and 41°.
To find:
The value of x.
Solution:
According to the exterior angle thereom, the exterior angle of a triangle is equal to the sum of opposite interior angles.
Using exterior angle theroem, we get
[tex](2x+30)^\circ=33^\circ+41^\circ[/tex]
[tex](2x+30)^\circ=74^\circ[/tex]
[tex](2x+30)=74[/tex]
On further simplification, we get
[tex]2x=74-30[/tex]
[tex]2x=44[/tex]
[tex]x=\dfrac{44}{2}[/tex]
[tex]x=22[/tex]
Therefore, the value of x is 22.
