The equation that models the sequence is: 6+6 each time.

To see what equation gives us the sequence, let's first try to find a pattern.
6 to 12 can be: x + 6, 2x, 3x -6.
12 to 24 can be: x + 12, 2x, 3x -12.
24 to 48 can be: x + 24, 2x, 3x - 24.
Let's see if we can find a common pattern.
2x is a common pattern.
Your equation is :
n = 2x.
I hope this helps!

Katherine and Shally had $288 altogether. Katherine gave 1/3 of her share to Shally and their father gave $68 to Shally. They no

erastova [34]

1/3 of $288 is $96 So, therefore Shally had $96 at first.
But They both didn't have the same amount of money after too because:
1/3 of $288 is $96
$96 + $68 = $164 So Shally has $164

Now, $288 - $96 = $192. So Katherine has $192

So therefore they did not have the same amount of money but 1/3 of $288 is $96

I think you mean six-hundred and seventy six.

6 ÷ 576 = 0.010416

Your company recently made a purchase of 25 identical tables. The purchase price after adding 5 percent sales tax was 1,706.25.

ELEN [110]

If c = the cost of one table, the cost of all 25 tables before sales tax is 25·c

Since the sales tax is 5%, or 0.05, the sales tax for 25 tables is 25·c·0.05

Adding the sales tax to the original cost of the 25 tables can give you:
25·c + 25·c·0.05 = 1706.25
1.05·25·c = 1706.25
26.25·c = 1706.25
c = $\frac{1706.25}{26.25}$ = 65

so the refund for 5 tables would be 5*65 = $325

Which ordered pair is a solution to the system of equations?

iren2701 [21]

(- 2, - 3) is a solution to the given system of equations.

Answer: Option D

<u>Step-by-step explanation:</u>

Given equation are not presented in proper format. So, let assume the given system of are as below,

2 x - y = -1

2 x -4 y = 8

Now, subtract the second equation from the first, we get

(2 x - y) -(2 x - 4 y) = -1 -8

3 y = -9

y = -3 (obtained this when divide by 3)

Substituting y = - 3 into the first equation, we get

2 x - (-3) = - 1

2 x = - 1 + 3

x = - 2 (obtained when divide by 2)

Now, the answer is (x, y) = (- 2, - 3)
