I think that is proportional
For this case the first thing we should do is find the percentage of people surveyed who said that pizza pizza was their favorite type of pizza.
We have then:

We are now looking for 52.5% of 1600 people.
For this, we make the following rule of three:
1600 ----------> 100%
x ---------------> 52.5%
Clearing the value of x we have:
Answer:
the most reasonable estimate for the number of Trinity Food Festival attendees whose favorite type of pizza is sausage pizza is:
x = 840
Answer:
Step-by-step explanation:
the 2nd one
OK so if 70% of students in 8th grade have siblings and 112 8th graders have siblings, then:
0.7(total 8th graders) = 112
total 8th graders = 112/0.7
total 8th graders = 160
And since the number of 8th graders is 5/6 the size of the 7th grade class:
5/6(7th grade class) = 160
5(7th grade class) = 960
7th grade class = 192.
The correct answer is D) 192.
Hope this helps

1) -5 + w/3 = -1
w/3 = -1 + 5
w = 4*3
w = 12
2) 24-3x = -27
-3x = -27 - 24
3x = 51
x = 51/3
x = 17
3) <span>-17 + n/5 = 33
n/5 = 33 + 17
n = 50 * 5
n = 250
4) A) </span><span>3m + 2 = -10
5) </span><span>25 = -75 - 5x
-5x = 25 + 75
x = 100 / -5
x = -20
6) D) </span><span>5 - 7x = 2
Hope this helps!</span>
