"One Sextillion "

4/ 3  = 1.3333.....  [repeating]

He sorts 12 more letters in every successive hour  compared to the previous hour

So

81 + 12  = 93

12

either 129 or 117

if you get reported and the moderators decide to take away points then yes that can happen

if inf meant infinity, the answer is infinity

$100

He took $100, then he gave it back so the store lost nothing. But then they had to give him $70 worth of stuff and $30

Everyone needs a great weekend

Well \(7^2 = 49^1\)

Reduction by 1/2 [ assuming that the smaller triangle is a dialation of the larger one ]

If you can rotate (or turn) a figure around a center point by fewer than 360° and the figure appears unchanged, then the figure has rotational symmetry.

Rotating "Z" by 180° gives the same image.....every other letter must be rotated  360°

Each sector spans 36°.....i to f  comprises three of these, counterclockwise....so....3 x 36° = 108°

if 6x-3y=30 and 4x=2-y then x+y= what

I. \(6x-3y=30\)

2. \(4x=2-y\)                  Side change with sign change

3. \(y=2-4x\)                 Insert in equation 1

\(6x-3(2-4x)=30\)  calculate

\(6x-6+12x=30\)      Side change with sign change and calculate

\(18x=36\)                         Divided by 18 on both sides

\(x=2\)                                Insert in equation 3

\(y=2-4\times 2\)                calculate

\(y=-6\)

   !

Which axis  ????

6x - 3y = 30

4x + y = 2

Multiply the second equation by 3

6x - 3y = 30

12x + 3y = 6

Add both equations

18x = 36

x = 2

Plug x back into either equation

4(2) + y = 2

y = -6

2 - 6 = -4

Solve the following system:
{6 x - 3 y = 30 | (equation 1)
4 x = 2 - y | (equation 2)
Express the system in standard form:
{6 x - 3 y = 30 | (equation 1)
4 x + y = 2 | (equation 2)
Subtract 2/3 × (equation 1) from equation 2:
{6 x - 3 y = 30 | (equation 1)
0 x+3 y = -18 | (equation 2)
Divide equation 1 by 3:
{2 x - y = 10 | (equation 1)
0 x+3 y = -18 | (equation 2)
Divide equation 2 by 3:
{2 x - y = 10 | (equation 1)
0 x+y = -6 | (equation 2)
Add equation 2 to equation 1:
{2 x+0 y = 4 | (equation 1)
0 x+y = -6 | (equation 2)
Divide equation 1 by 2:
{x+0 y = 2 | (equation 1)
0 x+y = -6 | (equation 2)
Collect results:
Answer: |x = 2             and           y = -6     So: x + y =2 + (-6) =-4

$130

To see why...the store is out $100 when the theft occurs.....when the guy comes back and buys $70 worth of stuff the store gets back $70 but also loses $70 worth of merchandise....so.....they are back where they started....down $100.....giving the guy back $30  means they are now down $130
