Answer:
90 students
Step-by-step explanation:
If 12/16 of the students will get a job within the first month, its the same as saying 3/4 will.
So, we can take 3/4 of 120, which is 90 students.
360/9=40
There are 40 "packs" of 9 students.
40*5=200 for the boys
40*4=160 for the girls
There are 200 boys and 160 girls.
A. g(x)=(4x)^2
All you have to do is graph each equation and see what matches g(x) on the graph given.
Answer:
x= -3 and y = 6
Step-by-step explanation:
so basically what you are trying to do is reduce into finding x and y
what you do is you want to find a number to multiply one of the equations in order to get the same x or y value does not matter which
so,...
we can do
either 20x or 15y
we will go with the smallest 15y
so for both equations multiply the whole thing by 5 for the first equation and by 3 for the second
5 x 5x+3y=3 --> 1
3 x 4x+5y=18 --> 2
we then get
25x+15y = 15 -->1
12x + 15y = 54 -->2
then now that you have the same Y values you can subtract ! which cancels out both the 15y
25x+15y = 15 -->1
- 12x + 15y = 54 -->2
13x =-39
so now x=-3 and all you have to do with x = -3 is sub this into either one of the equations that you started with !
x = -3
5(-3) +3y =3
-15 + 3y = 3
3y = 3+15
3y=18
y = 6!
