Kevin has 3 bags of apples weighing a total of 22 1/2 pounds.Two of the bags weigh 6 3/8 pounds and 3 1/4 pounds.How much does the third bag weigh?
Answers
3 bags total 22 and 1/2 bag1+bag2+bag3=22 and 1/2 two of the bags weight 6 and 3/8 and 3 and 1/4 so just assign them random bags bag1=6 and 3/8 bag2=3 and 1/4 subsitute
6 and 3/8+3 and 1/4+bag3=22 and 1/2 we have to add them by making the bottom number same
6 and 3/8+3 and 1/4 common one is 8 6 and 3/8+3 and 2/8 6+3/8+3+2/8 9+5/8
9 and 5/8+bbag3=22 and 1/2 subtract 9 and 5/8 from both sides bag3=22 and 1/2-9 and 5/8 bag3=22+1/2-9-5/8 bag3=22+4/8-9-5/8 bag3=21+8/8+4/8-9-5/8 bag3=21+12/8-9-5/8 bag3=21-9+12/8-5/8 bag3=12+7/8 bag3=12 and 7/8
answe ris 12 and 7/8 pounds
First, you change 6 3/8 and 3 1/4 to a common denminator. 8
6 3/8= 6 3/8 3 1/4= 3 2/8 (x2)
Then add those.
6 3/8+ 3 2/8 = 9 5/8
Then subtract 22 1/2 and 9 5/8. (Common denominator)
22 1/2= 22 4/8 (x4) 9 5/8= 9 5/8
the 3rd bag is 12 7/8 lbs.
You can also add each bag (lbs) to see if it gets to 22 1/2 Hope this helps!
Explain why it does not matter what letter or symbol is used to find an unknown number
Answers
A variable represents an unknown quantity. No matter which variable you use, it will represent the same unknown quantity, and the same process will be used to solve the problem. Which variable you use is irrelevant.
It's because the letter represents a number, so it doesn't matter what letter.

Find the Missing Hypotenuse
Answers
The original triangle had a hypotenuse of 26, a height of 10, and a base of 24. Using the Pythagorean Theorem, these measurements make sense.
The triangle's base has now been changed to 48, since 24 was doubled. The height of the triangle is still 10. Using the Pythagorean Theorem, which we just practiced with, we can find the missing hypotenuse, or the length of the ramp.
