For this question BODMAS should be used
BODMAS = Bracket Of Division Multiplication Addition Subtraction

SO, in 3-3x6+2. multiplication should be done first
= 3-18+2           Next addition should be done
= 3-16                And now subtraction
= -13

Answer =  -13

Solution 2

The answer for 3-3x6+2 is 17. For this you need to use PEMDAS (Please Excuse My Dear Aunt Sally) to solve the problem. First, M stands for multiplication so you do 3x6 which is 18. Then, A is addition so add 2 to 18 which is 20. Lastly, S stands for subtraction so you subtract 3 from 20 and you get your answer, 17.

Anyone know the answer to this simple little equation? It's giving me a bit of a tough time.. 3x^2 (4x-7)
Solution 1
12x2−13x−14 look it up on google to show you the graph

Solution 2
3x^2 (4x-7) = 12x^3 - 21x^2
Given that a:12=4:10 find the value of a.
Solution 1

The extremes are a and 10
The middles are 12 and 4

a     = 48/10
a     = 4.8

Therefore, the value of a = 4.8
Solution 2
A/12= 4/10

Cross multiply: 12*4= a*10
⇒ a= 12*4/10= 4.8

Final answer: a= 4.8
True, false, or open. Explain. 45/x-14=22
Solution 1
45/x - 14 = 22 
add 14 to both sides

45/x -14 +14 = 22 +14
45/x = 36
36 x = 45
x = 45/36 = 5/4 = 1.25

Simplify the following expression.
Solution 1
The first step for solving this expression is to express with a positive exponent using  a^{-n} X  \frac{1}{ a^{2}}  X b.
4 ×  \frac{1}{ a^{2} }  × b
Now calculate the product.
 \frac{4X1b}{ a^{2}  }
Before you get your final answer,, you must remember that any expression multiplied by 1 stays this same. This makes our final answer the following:
 \frac{4b}{ a^{2}}

Answer: C

Step-by-step explanation:

The grid shows a section of the beach in Coast City where each square has sides that are 100 yards long.

On a coordinate plane, the beach front is about 800 yards long. From the south pier to the north pier along harbor drive and park street, the distance is 1200 yards long.

Lisa walked from the South Pier to the North Pier along the beachfront. Deanna walked from the South Pier to the North Pier along Harbor Drive and Park Street. Which statement best describes the distances the two women walked?

a. Lisa walked about 400 yards farther than Deanna.

b. Lisa walked the same distance as Deanna.

c. Lisa walked about 400 yards less than Deanna.

d. Lisa walked about 400 yards.

Circle J has center J (4,-3) and radius 5 What is the measure, in degrees, of the arc with endpoints A (9,-3) and B (4,2)? Explain the process you used (in words) and include the work you did to find this answer.
Solution 1
This would be a 90° arc.

To find this, we can find the measure of the central angle that intercepts the arc.

The endpoints of the arc are at (9, -3) and (4, 2).
The slope of the line that passes through the endpoint (9, -3) and the center (4, -3) is given by 
m=(-3--3)/(9-4) = 0/5 = 0.

Since the slope is 0, this tells us it is a horizontal line.

The line that passes through the endpoint (4, 2) and the center (4, -3) has a slope that is undefined; it is a vertical line at x=4.  Numerically the slope is given by 
m=(2--3)/(4-4) = 5/0, which is undefined.

These slopes are negative reciprocals of one another; 5/0 and 0/5 (0 has no sign).  This means that these two lines would form a right angle, so the central angle of the circle is a right angle.  

The intercepted arc has a measure equal to that of the central angle, so the arc is also 90°.
Is y=-13/6x+5/3 same as 13x+6y=10 ?
Solution 1
13x + 6y = 10
-13x        -13x
         6y = -13x + 10
Divide 6y, 13x, and 10 by 6

y = -13/6x + 10/6

Simply 10/6 by finding the least common multiple of the numerator and denominator, which is 2. 10 divided by 2 is 5, and 6 divided by 2 is 3. 10/6 = 5/3

y = -13/6x + 5/3
Help How much will $5,000 invested at 6% compounded annually amount to after 10 years?
Solution 1
To find one year, here's the equation:
5000 + 0.06(5000)
For 10 years:
5000 + 10(0.06(5000))
5000 + 0.6(5000)
We can make it smaller:
1.6(5000) = 8000
You can make $8000
