Answer: x^2 - 4x - 12
Step-by-step explanation:
Factors are (x + 2) and (x - 6)
(x +2)(x - 6)
*multiply the first x by the second x and then by the -6
x^2 - 6x
* multiply the 2 by the second x and then the -6
2x - 12
* combine the two expressions
x^2 - 6x + 2x - 12
*simplify
x^2 - 4x - 12

1.5 * 35=
52.5 Km
Answer:
52.5 km/h
Step-by-step explanation:
convert in m/s
90km×1000m=90000m
1hr=3600sec
9000m÷3600sec÷35m/s

Answer:
See belowStep-by-step explanation:
Given:
Total number = 700Off grid class = 450Online class = 320Both = 275Based on the given we find the following
1) Off-grid class only:
450 - 275 = 1753) Online class only:
320 - 275 = 452) None of the classes:
700 - (175 + 275 + 45) = 2054) Not online:
700 - 320 = 3805) Not off-grid:
700 - 450 = 250Find the range of possible values of x satisfying:

Find the gradient of the line
3y + 2x = 1
how to guys
Answer:
-2/3
Step-by-step explanation:
The gradient of a line is its slope. You can just convert the equation to slope-intercept form (y=mx+b where "m" is the gradient/slope):
3y + 2x = 1
3y = 1 - 2x
y = 1/3 - 2/3x
y = -2/3x + 1/3
So, as we can see, -2/3 is the gradient/slope of the line.

What is the measure of Zx?
Angles are not necessarily drawn to scale.
B
42
109°
D
29
E
А
F
Answer:
a straight line has an angle of 180
therefore 180-109=71
71÷2 = 35.5
x is 35.5 degrees
The measure of x is 29 degree.
What is Parallel line?Straight lines that are always the same distance apart from one another are called parallel lines.No matter how far apart they are from one another, parallel lines can never intersect.As, Parallel line have property
Any two lines are considered to be parallel if the angles formed by them are equal.If the Opposite interior angles formed by two lines are equal, they are said to be parallel.If the Opposite exterior angles formed by two lines are equal, they are said to be parallel.If the Successive interior angles on the same side of the transversal are additional, two lines are said to be parallel.As, <CBA = <BAD (Alternate Interior Angle)
So, <BAD = 42
Now, <BAD + <BAC + <CAE = 180 (Linear Pair)
42 + 109 + x = 180
151 +x = 180
x = 180- 151
x = 29

Step-by-step explanation:
the nickels can add up to 60 nickels for 3$. then, i just started adding dimes until i get to $1.30 out of the remaining $1.40 (because we subtracted $3 from 60 nickels). we now have 73 coins. two more nickels adds 0.10, which finally gets us to the missing 1.40.

In a recent year, 27.4% of all registered doctors were female. If there were 55,600 female registered doctors that year, what was the total number of registered doctors?
Answer:
The total number of registered doctors is 202,920 rounded.
Step-by-step explanation:
Solve for (x) in this equation: 27.4/100 = 55,600/(x)
You will get the following equation: (x)= (100*55,600) / (27.4) which equals 202,919.708 rounded to 202,920
To double check, you can see that 27.4% of the total given (202,920) equals the 55,600.

You are really excited to have found a Puch Maxi Moped from the mid Eighties, and the spring weather is making you want to get out and ride it around. It doesn't run on straight gasoline, you have to mix the oil and gas together in a specific ratio of 2.4 fl. oz. of oil for every gallon of gasoline.
You have 3.75 gallon of gas. How much oil should you add?
Answer:
Step-by-step explanation:
You should add 9 fl. oz. of oil to your 3.75 gallons of gas.
Puch Maxi Moped from the mid-Eighties now since this moped doesn't run on straight gasoline, you need to create a special fuel mixture. This involves combining oil and gas in a specific ratio. The magic ratio here is 2.4 fl. oz. (fluid ounces) of oil for every gallon of gasoline.
You mentioned you've got 3.75 gallons of gas. To figure out how much oil you need, we can use some math. First, let's find out how much oil is required for one gallon of gas:
2.4 fl. oz. of oil/gallon x 1 gallon = 2.4 fl. oz. of oil.
So, for 3.75 gallons of gas, you'll need:
2.4 fl. oz. of oil/gallon x 3.75 gallons = 9 fl. oz. of oil.
You should add 9 fluid ounces of oil to your 3.75 gallons of gas to create the proper fuel mixture for your Puch Maxi Moped.
