I'm just going to give you the formula so you can learn
(2 3/5 ·7) + (5 3/4 ·4)
Answer:
<u>Add 3 to both sides of the equation</u>
Solution:
The first step is to basically realize that all it's asking you to do is to find a way to make the expression on the left (
) into an expression that is a perfect square. So what number should you add to both sides such that
can be factored into
? Well, we can approach it like this:
Since
can be turned into
, and our original form was
, we quickly realize that
. From there, we can easily tell that 
Plug this into our last value
to get 16. Therefore, if we compare this with our original equation again
, we notice that 13 + j = 16.
Thus, j = 3 for the last answer.
Add 3 to both sides of the equation.
Note: With more practice, you will quickly gain enough intuition to notice that
is very close to
which can be factored into
. But for now, the solution above will suffice. I hope this helps :))
A loss of 36 points is -36. A gain of 24 points is +24.
-36 + 24 = -12
This means that there was a loss of twelve points.
Answer:
Step-by-step explanation:
100 bushels of corn are divided among 100 people: men, women, and children. Men get 3 bushels each. Women get 2 each. Children get 1/2 bushel each. How can the bushels be distributed?
Answer: x = -3 + √3 or x = -3 - √3
