Represent algebraically: If b baseball cards were divided equally is total number of cards is 150
<u>Solution:</u>
Given that, if “b” baseball cards were divided equally among 3 people, each person would receive 25 cards less than if the “b” baseball cards were divided equally between 2 people.
We have to represent it in algebraic form.
Now, number of cards per each person when divided among 3 = number of cards per each person when divided among 2 – 25
Hence, total number of cards are 150
((x+2)(x+2))-((x-5)(1))=A
x^2+4x+4-x+5=A
x^2+3x+9=A
You would use this formula for the problem...
(C=2πr) The circumference equals 2 multiplied by pi and radius.
In this problem it says diameter, but the diameter is just twice the length of the radius, so just multiply the radius by 2. Plugin your number.
C=2π(2) since 2 is half of 4, that's your radius.
Your answer is roughly C= 12.57.
You're welcome.
