Answer:
Okay so Jack started with 50 chocolates, and ended with 2.
The simple way to calculate it would be by realizing that Jack only distributed 48 chocolates. We can find how many times 3 fits into 48 by dividing
48
÷
3
=
16
.
Using algebra, we substitute the value we want to find with
x
. Here what we want to find is the number of friends that were at Jack's party.
We know that he started with 50 chocolates, then distributed
3
×
the number of friends present (which is
x
).
We write that down as
50
−
3
x
(It's minus because when chocolates are distributed, Jack is taking away from what he has.)
We know that after this, there were only 2 chocolates left, so it's
50
−
3
x
=
2
Then we proceed by moving all the numbers to the right until only
x
is left:
−
3
x
=
2
−
50
−
3
x
=
−
48
x
=
−
48
−
3
x
=
16
Conclusion: The number of people that attended the party was 16.
Step-by-step explanation:
Answer:
-1.1+0.4i
Step-by-step explanation:
Multiply the numerator and the denominator by
You write it as a improper fraction first*
20
-----
8
and then u divide 8 into 20
and we know that it goes in it 2.5 times
so simply from here
it is 2.5%
I'm pretty sure it's A.
But don't count on it
Divide 170 by 250 to get the percent and you end up with 68. You do this because you know how much you have and if you only have 170 of 250 you must divide to find your percent.
