Answer:
a = -11, 17.
Step-by-step explanation:
-7 = |a-3| / -2
Multiply both sides by -2:
|a - 3| = 14
So a - 3 = 14
Giving a = 17
or
a - 3 =- -14
giving a = -11.
Checking these values:
-7 = |17-3| / -2 = 14/-2 = -7
- so a = 17 is a solution.
-7 = |-11-3| / -2 = 14/-2 = -7
so a = -11 is also a solution.

Answer:
The end answer is 669.4
Step-by-step explanation:
So you take the volume of the fish tank: 51*39*28=55692, but the tank is only 95% full, so you take 55692 and divide it by 100 and multiply it by 95, you get 52907.4. Then you calculate the volume of the log: 3.14*5^2*44=3454.
Now that we know these values, we take the volume of the water which is 52907.4 and add the volume of the log 3454 which gets you 56361.4.
Now we know the combined volume of the water and the log, we can remove the volume of the tank, which will still be holding the water that hasn't exceeded the capacity of the tank: 56361.4-55692=669.4
So then we know what has exceeded the capacity of the tank, which is how much water has spilled
So the water spilled equals 669.4 cubic centimetres of water.
Answer:
B
Step-by-step explanation:
I think n should be squared, right? and isn't the coefficient 8? But i do know both terms are negative, and that's the only answer.
The number of ways you can choose 5 beach towels from a selection of 8 to bring on vacation is a combination problem
<h3>Permutation and combination</h3>
Permutation has to do with arrangement while combination has to do with selection.
When choosing an object from other pool of object, we will have what is called combination.
From the given question, we are told that the number of ways you can choose 5 beach towels from a selection of 8 to bring on vacation, since they are selecting, hence the situation involves combination.
