Step-by-step explanation:
Explain what needs to be fixed.
2n + 10 = -2
2n = 12 Step one
n = 6 Step two
Answer:
step one needs to be fixed... you are supposed to subtract 10 from both sides of the equation.
Step-by-step explanation:
STEP 1: Move all terms not containing n to the right side of the equation.
[tex]2n=-12[/tex]
STEP 2: Divide each term by 2 and simplify.
[tex]n=-6[/tex]

Answer:
The slope of UV = 4
Step-by-step explanation:
Given the points
U(3, 1)V(-1, 2)Finding the slope of UV
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(-1,\:1\right),\:\left(x_2,\:y_2\right)=\left(-2,\:-3\right)[/tex]
[tex]m=\frac{-3-1}{-2-\left(-1\right)}[/tex]
[tex]m=4[/tex]
Thus, the slope of UV = 4

A
18.75%
B
81.25%
C
23.07%
D
16%
Given:
Laura has 160 pounds of green beans at her vegetable stand.
She sells 10 pounds of green beans every hour.
To find:
The percent decrease in green beans after 3 hours.
Solution:
We have,
Beans sold in 1 hour = 10 pounds
So, Beans sold in 3 hours = 30 pounds
Decrease in green beans after 3 hours is 30 pounds.
Now,
[tex]\%\text{Decrease}=\dfrac{\text{Decrease in green beans after 3 hours }}{\text{Initial amount of green beans}}\times 100[/tex]
[tex]\%\text{Decrease in green beans after 3 hours}=\dfrac{30}{160}\times 100[/tex]
[tex]\%\text{Decrease in green beans after 3 hours}=\dfrac{300}{16}[/tex]
[tex]\%\text{Decrease in green beans after 3 hours}=18.75\%[/tex]
Therefore, the correct option is A.

a piece of wire is 28cm in length is cut into two parts, each part bend to make a square. given that area of square is 416m^2. find the perimeter of each square.
Answer:
25.488 cm and 2.512 cmStep-by-step explanation:
Note: the area of squares is 41 cm² but not 416 m², typo
Let the sides of squares be x and y
Based on given we have equations:
4x + 4y = 28x² + y² = 41Simplify the first equation
4x + 4y = 28x + y = 7x = 7 - ySubstitute x to solve for y:
(7 - y)² + y² = 4149 - 14y + y² + y² = 412y² - 14y + 49 - 41 = 02y² - 14y + 8 = 0y² -7y + 4 =0Solving we get:
y= 6.372 cm or y= 0.628cmThen
x = 0.628 cm or x = 6.372 cmPerimeter of each square is:
4*6.372 = 25.488 cmand
4*0.628 = 2.512 cmhow do I find the percentage of filled seats verus non filled seats for a class
Answer:
since i dont have data this is the best i can do
Step-by-step explanation:
non-filled seats diveded by total number of seats, everything multilped by 100 gives you percentage of non-filled seats.
Filled seats diveded by total number of seats, everything multilped by 100 gives you percentage of filled seats.
total should add up to 100

The complete table will be:
x y
1 5
0.8 4
0.4 2
Step-by-step explanation:
Given rule is:
y = 5x
In the given rule, x is multiplied by 5 to get the values of y. The same rule can be manipulated to find the value of x in terms of y.
[tex]\frac{y}{5} = \frac{5x}{5}\\x = \frac{y}{5}[/tex]
Putting y = 5
[tex]x = \frac{y}{5}\\x = \frac{5}{5}\\x = 1[/tex]
Putting y = 4
[tex]x = \frac{y}{5}\\x = \frac{4}{5}\\x = 0.8[/tex]
Putting y = 2
[tex]x = \frac{2}{5}\\x = 0.4[/tex]
Hence,
The complete table will be:
x y
1 5
0.8 4
0.4 2
A 5-ounce can of tuna costs $0.90. A 12-ounce can of tuna costs $2.40. Which is the better buy?
Answer:
To find out which one is the better buy we have to find out what the unit price of each one is. To find a unit price you divide the ounce by the cost.
Step-by-step explanation:
5/90=18 cents
12/240=5 cents
the 12 ounce can is less per ounce so the 12 ounce can is the better buy.

What is the slope for the line 8x-4y=24
Answer:
the slope is 2
Step-by-step explanation:
subtract 8x from both sides to get -4y = -8x + 24
then divide by -4 to get:
y = 2x - 6
Find the slope of the line graphed below.
Answer:
-3/5
Step-by-step explanation:
So first, you have to find out the two points :
(-1,-1), and (4,-4)
Next, you have to put into this formula:
y1-y2/x1-x2
The y values in our points are -4 and -1, and our x values are 4 and -1. Lets now substitute:
-4-(-1)/4-(-1)
Now simplify: -4+1/4+1, and solve and you will get -3/5 as the slope
