you need to get a common denominator which would be 20
5 10/20 + 8 8/20 + 8 5/ 20 =
21 23/20
21 + 1 3/20
22 3/20
Answer:
AB = 2*sqrt(5) or
AB = 4.47
Step-by-step explanation:
AB is the hypotenuse of a right triangle A and B and the corner where 2 and 4 meet.
The length of AB is governed by the Pythagorean Theorem.
AB^2 = x^2 + y^2 Substitute 2 and 4 for x and y
AB^2 = 2^2 + 4^2 Expand the right side
AB^2 = 4 + 16 Add the right side
AB^2 = 20 Take the square root of both sides
sqrt(AB^2) = sqrt(20)
Factor 20 = 2*2 *5
Rule: when taking the square root of a number the pairs can take 1 member of the pair outside the root sign and throw the other one a way.
AB = 2 * sqrt(5) One of the roots has been thrown away.

Check 202 was written out for 68.28. You know this given the previous balance of 538.65 and the resultant balance of 470.37.
538.65-470.37=68.28
the next transaction of deposit of 400.00 gives a balance of 1170.37.
The next check 203 was written for 499.39 given the previous 1170.37 balance minus the subsequent balance of 670.98=499.39
