11/17 = it has a period of 16 digits, which means it repeats every 16 digits.

1/9 + 2/9 =3/9 =1/3

12.70 - 2.20 =10.50

$10.50 / $1.50 =7 miles Tom travelled.

I think it is this...repeating:

0.647 058 823 529 411 764 705 882 352 941 176 470 588 235 294 117

Sorry Tony..... there is no solution to this form..... are you sure you didn't leave something out?

A6/a3  = 2A/a

if you meant   a6/a3 = 2

if you menat a^6/a^3 = a^(6-3) = a^3

Approximately    5 / 1.7 ~~  3  

You are correct Max....Thanx !     Sometimes I think the low light affects my solar calculator.....or my vision.....or my brain!  

....as a further interpretation of the cost line   When x= 0  (this is when you have produced 0 cupcakes) your start-up, or fixed cost are $36  (the y-axis intercept)

The slope is defined as  how much the graph rises over how much the graph 'runs' horizontally

rise / run  = slope       if you graphed this line and looked at an x point then went 10 points to the right, you would see the graph would go up 9  units higher......

This tells you that to produce 10 more cupcakes....it costs 9 more dollars.

DO the stuff in parentheses first then the exponents then the multiplication then the addition or subtraction.

 3(-3)^2-5(-3-2)^2

=3(9) - 5(-5)^2

=27 - 5 (25)

=27-125

= -98

Equation for a line is  y = mx + b  where  m = slope  and  b = y-axis intercept

You are given two points on the line    100, 126        and     120, 144

Slope =  (y1-y2) / (x1-x2) ====   rise/run  =====    (126-144)/(100-120) =  -18/-20  = 9/10 = slope

so, so far    y = 9/10 x + b   

Substitute in either one of the points to calculate 'b'

126 = 9/10 ( 100)  +  b

126 = 90 + b

b = 36  = y- axis intercept                                    y= 9/10  x    +   36     is your line        

I agree with Melody ....Mostly....

y = mx + b   is the equation of a line with slope  m   and  y-axis intercept   b

you are given 'm' = 0.5     so your line equation becomes   y = .5 x + b

you are given the 'x' axis intercept....(this is where y = 0) as  28, 0   so substitute this value into your equation to find 'b'

y = .5x + b

0 = .5 (28 ) + b

-14 = b    

so your line equation becomes:

y = 0.5 x - 14   

Simplify the following:
3×(-3)^2-5 (-3-2)^2

-3-2 = -(3+2):
3×(-3)^2-5 -(3+2)^2

3+2 = 5:
3×(-3)^2-5 (-5)^2

Multiply each exponent in -5 by 2:
3×(-3)^2-5×(-1)^2×5^2

5^2 = 25:
3×(-3)^2-5×(-1)^2×25

(-1)^2 = 1:
3×(-3)^2-5×25

(-3)^2 = 9:
3×9-5×25

3×9 = 27:
27-5×25

-5×25 = -125:
27+-125

27-125 = -(125-27):
-(125-27)
Answer: |-98

5/4 x 28 =35 pens sold

The supply store sells 4 pencils for every 5 pens.The store sold 28 pencils yesterday.How many pens did it sell?

Obviously:

y =2^k and

k =Log(y) / Log(2)

Can be seen as two series:

1) (-1)^2 + (-1)^4 + (-1)^6.........+(-1)^2016=+1008 positive terms.

2) (-)^1 + (-1)^3 + (-1)^5...........+(-1)^2015=-1008 negative terms.

So, +1,008 -1,008 =0

2) Can also be summed up on Wolfram/Alpha as follows:

∑[ (-1)^(2n) +(-1)^(2n-1)] , n=1 to 2016, which gives this:

sum_(n=1)^2016((-1)^(2 n)+(-1)^(2 n-1)) = 0

2apples-1apple=1 apple

3 baskets = 120 lbs

120/3= 40lbs

1 baskets = 40 lbs

40*4=160lbs

4baskets=160lbs

or

3x=120,4x=?

x=40

4*40=160lbs

determine the distance between (-3,1) and (5,-6) by graphing and connecting the points, creating a right triangle, and applying the pythagorean theorem

-2^2 can be either:

=(-2*-2)

=4

or

=-(2*2)

=-4

Don't know what Math 3 is?.
