Answer:if i had 2 try it would b a
Step-by-step explanation:
1/3 you simplify 3/18 to 1/6 then it then goes onto 1/3
Answer:
x=3/2

Answer:
![\left \{ {y\leq 25-x} \atop {y\geq 3x}} \right.](https://tex.z-dn.net/?f=%5Cleft%20%5C%7B%20%7By%5Cleq%2025-x%7D%20%5Catop%20%7By%5Cgeq%203x%7D%7D%20%5Cright.)
The graph is attached.
Step-by-step explanation:
Let be "x" the number of metamorphic samples and "y" the number of sedimentary samples.
You know that you want to to have at most 25 samples, then:
![y\leq 25-x](https://tex.z-dn.net/?f=y%5Cleq%2025-x)
And you want to have at least 3 times as many sedimentary samples as
metamorphic samples, then:
![y\geq 3x](https://tex.z-dn.net/?f=y%5Cgeq%203x)
Therefore, the system of inequalities that model the situation is:
![\left \{ {y\leq 25-x} \atop {y\geq 3x}} \right.](https://tex.z-dn.net/?f=%5Cleft%20%5C%7B%20%7By%5Cleq%2025-x%7D%20%5Catop%20%7By%5Cgeq%203x%7D%7D%20%5Cright.)
The y-intercept of the line
is:
![y=25-(0)\\\\y=25](https://tex.z-dn.net/?f=y%3D25-%280%29%5C%5C%5C%5Cy%3D25)
And the x-intercept is:
![0= 25-x\\\\x=25](https://tex.z-dn.net/?f=0%3D%2025-x%5C%5C%5C%5Cx%3D25)
Knowing this, you can graph the line
The y-intercept of the line
is:
![y=3(0)\\\\y=0](https://tex.z-dn.net/?f=y%3D3%280%29%5C%5C%5C%5Cy%3D0)
And the x-intercept is:
![0= 3x\\\\x=0](https://tex.z-dn.net/?f=0%3D%203x%5C%5C%5C%5Cx%3D0)
Knowing this, you can graph the line.
Observe the graph attached, where the solution of the system of inequalities is the intersection of the regions.
Answer:
n = 32 - 14 (= 18)
Step-by-step explanation:
You haven't given the answer options, however I assume it will be written in this form. I.e. the number of cupcakes still needed is just the total number of students (32) minus the number that Jenna bought (14).
so n = 32 -14 (=18)
