Answer:
n=-3.1
Step-by-step explanation:
To solve this, first subtract 3 from both sides of the equation to get 2n=-6.2. Next, divide both sides of the equation by 2 n order to get the final answer of n=-3.1

Answer:
12.5 pie , 39.25 using pie=3.14, and 39.28 to be exact
Step-by-step explanation:
BTW n=pie
10in= Diameter
5in=Radius
Area=n5^2
= 25n/2
=12.5n
12.5 times 3.14= 39.25
22/7 times 12.5= 39.2857143

you use 4 gallons of water on 30 plants in your garden. At the rate,how much water will it take to water 45 plants
Answer:4 gallons of water ... 30 plants
x gallons of water = ? ... 45 plants
If you would like to know how much water will it take to water 45 plants, you can calculate this using the following steps:
4 * 45 = x * 30
180 = 30 * x /30
x = 180 / 30
x = 6 gallons of water
Result: You will use 6 gallons of water to water 45 plants.

You lose 2 points every time you forget to write your name on a test. You have forgotten to write your name 4 times. What integer represents your change in points from forgetting to write your name?
Answer:
-8
Step-by-step explanation: since it says Times, (for me times is multiplication) you would multiply -2 and 4. negative 2 would be from that person losing 2 points. and 4 since it is your total amount of times you have forgotten to write your name. so, -2 x 4 = -8.
how i got -8. both signs from -2 and 4 are different, and when they are different the answer will always be negative.

Solve the equation for p, then justify your reasoning. -9p - 17 = 10
Answer:
p=-17/9 or p=-1.8889
Step-by-step explanation:
-9p-17=10
add 17 to each side
-9p-17+17=10+17
-9p=17
divide both sides by -9
-9p/-9=17/-9
p=-17/9
or p=-1.8889
Solution of equation - 9p - 17 = 10 is p = -3.
What is equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
For example, 3x – 5 = 16 is an equation.
Given equation
- 9p - 17 = 10
Add 17 to both sides
- 9p - 17 + 17 = 10 + 17
Adding the numbers
- 9p = 10 + 17
Adding the numbers
- 9p = 27
Divide both sides by - 9
-9p/ - 9 = 27/ - 9
Cancel terms that are in both the numerator and denominator
p = 27/ - 9
Divide the numbers
p = -3
Hence, p = -3 is the solution for equation - 9p - 17 = 10

Find the slope of the line passing through the points (-5,6) and (6,6).
slope:
Answer:
0
Step-by-step explanation:
the equation on finding slope is y2 - y1/x2 - x1
so it is...
6 - 6 = 0
6 - -5 = 11
0/11 but that doesnt work so I believe the slope is zero because the denominator is not the one being a 0
hope I helped ;)
Answer: its a zero slope

Find the midpoint of the segment.
A. (4, 2)
B. (1, 0)
C. (-4, 0)
D. (0, 1)
Answer:
B. (1, 0)
Step-by-step explanation:
9514 1404 393
Answer:
B. (1, 0)
Step-by-step explanation:
You can count grid squares on the graph to find the point that is 4 of the 8 units horizontally between the points, and 2 of the 4 units vertically between the points. That will be ...
C +(4, 2) = D -(4, 2) = (1, 0)
__
Or, you can use the midpoint formula:
M = (C +D)/2
M = ((-3, -2) +(5, 2))/2 = (-3+5, -2+2)/2 = (2, 0)/2
M = (1, 0)
The midpoint is (1, 0).
What is the distance from M to N?

Suzanne is putting a fence around her rectangular garden. The length of the garden, x, is 4 feet more than the width. The perimeter of the garden is 32 feet. Write an equation to find the length of the garden.
Enter the correct answer in the box.
Answer:
Length=10 feet
Width=6 feet
Step-by-step explanation:
Let width (W) of the garden is x feet
Then Length=L=4+x feet
Perimeter=P=2(W + L)
P=2(x+x+4)
32=4x+8
4x=32-8
x=24/4=6 feet
W=6 feet
L=10 feet

a rectangle has a length 3 meters more than three times the width. the area of the rectangle is less than 90 meters squared. write an expression that represents all possible widths (use the variable x) of the rectangle. write your answer as an inequality, a < x < b.
Answer: -6<x<5
Step-by-step explanation:
Given
Length is 3 m more than three times the width
Suppose width is x
So, the length is 3x+3
The area of a rectangle is [tex]length\times width[/tex]
Area= [tex](3x+3)x<90[/tex]
[tex]\Rightarrow 3x^2+3x-90<0\\\Rightarrow x^2+x-30<0\\\Rightarrow x^2+6x-5x-30<0\\\Rightarrow (x+6)(x-5)<0\\\Rightarrow -6<x<5[/tex]

Answer:
8
Step-by-step explanation:
8*4 is 32 8*9 is 72
so, it is 8
since it is distributive property 8(4+9)
Answer:
8
Step-by-step explanation:
1) simplify the equation
32+72=104
104=4x+9x (distibute the "x")
104=13x
x=8
hence the "blank" is 8
