Answer:
(x-2 )( x + 1) = (-2 - c)
Step-by-step explanation:
C= - 1 = -x
We cna either multiply x and c until we find HCM before imputing x value and c value that is unknown variable.
To find that we can say x = the average of 1000 + $800 = $900 and work out the difference between the two.
We can use a new variable for half that difference to ensure we add or subtract to find the value 1000 or -1000 again.
So that $1000 - $847 = $153 half this difference is 2/3y so that 4/3 = $153 and 1/3 = 33.333 as we are working with 3 numbers then 1/3 or 2/3 for example could show a debit;
Balance of each 1000 would look like
2/3y + x + c
= c + xy - y1/3
to show smaller amounts for the last 2 debits.
Approximately 15.4 years
I multiplied 20,000 by 0.13 and got 2,600. Then I subtracted 20,000 from 60,000 to get 40,000. Finally I did 40,000 / 2,600 and got 15.4
Answer:
4b = 7
Step-by-step explanation:
5x = 20 has solution x = 4
8w = 32 has solution w = 4
12y = 48 has solution y = 4
whereas 4b = 7 has solution b = 
The other 3 equations have a solution of 4 making 4b = 7 the odd one out
