Answer:
-1 1/6
Step-by-step explanation:
Use a common denominator first to convert all the fractions so they can be easily added or subtracted.
Common denominator is 18 since 3, 6, and 9 can all evenly divide into 18
1/3 = 6/18
1/6 = 3/18
2/9 = 4/18
So now you have
-6/18x - 3/18 = 4/18
add 6/18x to both sides so you can make the number with the variable positive
6/18x - 6/18x - 3/18 = 4/18 + 6/18x simplifies to - 3/18 = 4/18 + 6/18x
subtract 4/18 from both sides
- 3/18 - 4/18 = 4/18 - 4/18 + 6/18x simplifies to - 7/18 = 6/18x
Divide both sides by 6/18 so x is alone on the one side
( - 7/18) / ( 6/18) = ( 6/18x) / ( 6/18) simplifies to ( - 7/18) / ( 6/18) = x
When you divide a fraction by a fraction, the bottom fraction gets flipped over then you multiply the two new fractions straight across
so the new equation looks like this
- 7/18 times 18/6 and you multiply -7 x 18 = -126 and the bottom is 18 times 6 = 108 you now have -126/108
x = -126/108 which simplifies to - 1 18/108 which can still be simplified more to -1 1 / 6 since 108 can be divided by 18 that gives you 6.
Answer:
The largest number of elephants which Daniel could have is 2007
Step-by-step explanation:
The theorem behind it is if u and v are coprime positive interger then
N= 2UV -u-v
Where u = 28 v=37
N= 2×28×37- 28-37
N= 2007
Answer:
1.2 years
Step-by-step explanation:
The value of a certain account after t years is given by :
B = 600 × 1.2t dollars ....(1)
We need to find how long will it take for the value of the account to increase to $900 i.e. we need to find the value of t.
Put B = $900 in equation (1).
So, it will take 1.2 years of the account to increase to $900.
The answer is b just because inequality
