Hello,
|190-210|+|19-21|+x=100
==>|-20|+|-2|+x=100
==>20+2+x=100
==>x=100-22
==>x=78
Thus there is a mistake in your question !
Answer:
1,360
Step-by-step explanation:
Ok, so for the first 6 questions, if each one can be answered 4 different times, that would mean that it would be 6 to the 4th power (or 6 x 6 x 6 x 6)
That would be 1296.
Then, we have the other 8 questions, that can be answered 2 different ways. That would be represented as 8 to the second power (or 8 x 8)
That would be 64.
Now, we have to add the two numbers together to get the total. 1296+64 = 1,360
That's how you get the answer! I hope this is correct!
Your slope is -2 for every 5 and your y intercept is 2
= 7/8 − 1/5
= ((7 × 5) − (1 × 8)) / (8 × 5)
= (35 - 8) / 40
= 27/40
SO, 27/40 minutes are NOT spend on instructions.
Hope I was able to help! :)
