Step-by-step explanation:
Brackets is the bigger version of parentheses, you first solve the questions inside the parentheses, then move onto brackets.
For example, this question:

![5x-y[7-4(z-y)]](https://tex.z-dn.net/?f=5x-y%5B7-4%28z-y%29%5D)
<u>plug in x, y, and z.</u>
![5(-1)-(-2)[7-4(3-(-2))]](https://tex.z-dn.net/?f=5%28-1%29-%28-2%29%5B7-4%283-%28-2%29%29%5D)
![5(-1)-(-2)[7-4(5)]](https://tex.z-dn.net/?f=5%28-1%29-%28-2%29%5B7-4%285%29%5D)
![5(-1)-(-2)[7-20]](https://tex.z-dn.net/?f=5%28-1%29-%28-2%29%5B7-20%5D)
![5(-1)-(-2)[-13]](https://tex.z-dn.net/?f=5%28-1%29-%28-2%29%5B-13%5D)
![-5-(-2)[-13]](https://tex.z-dn.net/?f=-5-%28-2%29%5B-13%5D)

Answer:
option A is correct that is 17.
Step-by-step explanation:
We have been given a histogram which is showing y-axis represents number of fundraisers and x-axis represents funds
So, we need to find the number of fundraisers raised funds between $600 and $800
In $600- $800 funds interval the number of fundraisers are 10+7 =17
So, option A is correct that is 17.
Answer:
99000 meters.
Step-by-step explanation:
We have the swimmer going at 50 m / s, and we want to know where he is going in 33.3 minutes.
The first thing is to pass the time from minutes to seconds, we know that 1 minutes is 60 seconds, therefore:
33.3 min * 60 s / 1 min = 1998 seconds
Now to know the distance is to multiply this time by the speed they give us, like this:
1998s * 50m / s = 99900 m
Which means that in that time and at the speed of the swimmer, he has traveled 99000 meters.
