First you find the circumference... 2pi*r... and then you multiply that by 2.125. To find out the total amount of meters that the man walks!
I dont really know how to explain it so i just solved it (the answer is boxed) but i hope this helps !
<h3>20 subtracted from three times a number is 6 more than the number. Then the number is 13</h3>
<em><u>Solution:</u></em>
<em><u>Given statement is:</u></em>
20 subtracted from three times a number is 6 more than the number
We can translate the sentence into algebraic expression
Let "a" be the unknown number
Then,
20 subtracted from three times "a" is 6 more than "a"
Which means,
3a - 20 = 6 + a
3a - a = 6 + 20
2a = 26
Divide both sides by 2
a = 13
Thus the number is 13
Well we have to do 8675 + 2235 + 1850 + 250 which equals $13,010
so the answer is $13,010
