N+15=M N+M=-47 -47-15=-62 -62/2=-31 -31+-16=-47, therefore the answer is N=-31 and M=-16
first term: 5x-5y
common difference: -x/2 + y
You multiply them together so it is 360 it will sometimes also look like this
8(45+7) and with that you would then just multiply the 8 to the 45 and the 7
<h3>
Answer: -√46 is between -7 and -6</h3>
==========================================================
Explanation:
List out the perfect squares
- 1^2 = 1
- 2^2 = 4
- 3^3 = 9
- 4^2 = 16
- 5^2 = 25
- 6^2 = 36
- 7^2 = 49
- 8^2 = 64
and so on. We can see that 46 is between 6^2 = 36 and 7^2 = 49.
We can say 6^2 < 46 < 7^2
Applying the square root to all three sides leads us to 6 < sqrt(46) < 7
Now multiply all three sides by -1. This will flip the inequality signs
We go from
6 < sqrt(46) < 7
to
-6 > -sqrt(46) > -7
It might help to order things from smallest to largest to get this
-7 < -sqrt(46) < -6
This means -sqrt(46) is between -7 and -6 on the number line
See the diagram below.
If he makes 9/10 all the time we he hits 100 feee throws he would have made 90/100 so 90 + 90 = 180 can expect to make .
