Answer:
99
Step-by-step explanation:
Through some clever algebra, we can combine our first two equations using the fact that

We have the a² and the b² in the equation
, and we <em>almost </em>have a 2ab in the equation
. To get that 2ab, we can simply double both sides of the first equation to get
. From there, we'll add the first two equations together, giving us the summed equation

And since
, we can equivalently say that

<u>ANSWER: </u>
Jack picked 10 ears of corn. The amount of corn left is
ears of initial corn.
<u>SOLUTION:
</u>
Given, Jack picked 10 ears of corn.
Now the total corn present is 10 ears.
He and two of his sisters ate two each.
Then, remaining corn = 10 ears – eaten corn
= 10 – 2 (by him) – 2 (by his first sister) -2 (by his second sister)
= 10 – 6 = 4
Now, the amount of corn left in fraction is remaining corn divided by initial corn.
Left over corn = 

Hence, the amount of corn left is
ears of initial corn.
Three and one tenths. 3+1/10
