Step-by-step explanation:
The problem is saying 2/5 squared by -2 times -3 multiplied by itself 4 times.
2/5 multiplied by itself -2 times looks like this: -2/5 times -2/5.
-3 multiplied by itself 4 times looks like this: -3 times -3 times -3 times -3.
Put the two together and it looks like B.
Answer:
Rounded to nearest tenths = 0.2
Answer: Aiden bought 8 notebooks and 5 covers.
This is a system of equations problem. To solve this, we have to write 2 different equations and then solve them.
Our equations are:
x + y = 13
1.37x + 1.08y = 16.36
Where x is the number of notebooks and y is the number of covers.
To solve these equations, you can use anyone of these methods:
1) Graphing
2) Substitution
3) Elimination
The easiest way would be to graph them with a graphing calculator and find the point of intersection.
If you decrease number by 50% of that number you are basically dividing with 2 hence the answer is 15.
