Answers

Put the numbers in order from smallest to largest:
21,34,45,53,71,88

Since there are an even amount of numbers you must take the middle two and find the average(add them together then divide by 2)
45+53=98
98/2=49

Can you explain how to use the combine place values strategy to find 223-119

Answers

223
- 1 1 9
---------- so combine just means you going to take two numbers to subtract. So since 3 is small then 9 your going to use combine which is taking 19 from 23 so count back 20 21 22 23 so you counted back 4 spaces so you put 4 under the 9 you had no tens so you put a zero under the1 the now you just subtract2-1=1 so your answer is 109 that is called combine place value

223
-119

What is a 33.33% increase followed by a 50% decrease?

Answers

33.33-50=-16.67%
hope that helped :)

If you let x = the original amount, then an increase of 33.33% would be represented by

x + (x × 33.33%)

Then if there was a decrease of 50%, you would now have

[x + (x ×33.33%)] × 50%

rewrite with decimal instead of %

[x + (x × .3333)] ÷ 2

The brackets and parentheses are important to tell the order in which to proceed.
