You are not giving enough information but in one of the calsses the average of student's height might be greater than the other class beacause one of the two classes needs to have 1 extra person than the other calss
8 (2x - 14) + 13 = 4x -27
distribute 8 through the parentheses
16x - 112 + 13 = 4x - 27
combine like terms
16x - 99 = 4x -27
subtract 4x from each side
12x - 99 = -27
add 99 to each side
12x = 72
divide each side by 12
x = 6
There is 3 variable, in this case, painters, walls and time(minutes). You need to find how many painters needed and provided information on the walls and time(minutes).
Increasing walls will cause more painter needed. It was reversed in time which was increased time will cause less painter needed.
In this case, you need to divide the variable walls with time since it reversed so: 27wall/9 minutes
It equal to : 3 walls/minute
Information provided is:
3 painters= 3 walls/3 minutes
Equal to : 3 paintes= 1 wall/minute
To make it 3 walls/minute, the painter needed will be:
(3 walls/minute) / (1 wall/minute) x 3 painters= 9 painters
Answer: 9 painters
Answer:
1/4= 25%
Step-by-step explanation:
(10v + 45) = 5(2v + 9)
To factor find a number that can go flu shot into the 2 numbers given. In the question you posted, th at number was 5. 5 could go into 10v and 45.
If you need a better explanation just as in the comments.
