Answer:
x=11, y=2
Step-by-step explanation:
We can set 1 equal to x-5y and then solve for x. and y.
x = 5y+1
y = x-1/5
We can use this information and plug back in the values for 3y-x or x-5y.
We can set -3 = 3y-x or 1 = x-5y.
To solve for x using -3 = 3y-x we can swap the values of x and y which would make it -3 = 3(x-1/5)-5(x-1/5)+1.
We can do a bit of algebra which would get us x = 11.
Knowing that y = x-1/5 we can plug in 11 for x. y = 11-1/5.
y=2
x=11, y=2

Answer:
I am gonna take a guest and say <em>178</em> for number 3. And for number 4, the answer is <em>44.</em>
Step-by-step explanation:
For number 3, I added 76 and 102 which equals 178. For number 4, I put n+6+3n-10=180 because its a triangle. Do the math and you get n=44. Correct me if I am wrong; I tried my best.

Answer: no
Step-by-step explanation:
Each of the domain values, x, output a single value, y, in a function.
This set is a not function, because the domain value 3 has two outputs.
Answer:
765
Step-by-step explanation:
First, find the number of sophomores
3600 * 3/8 =1350
Use the number of sophomores and multiply by 3/5 to find the amount of sophomores opposed to rock climbing
1350 * 3/5 =810
Then subtract the amount of sophomores from the total amount of students
3600 - 1350 =2250
And multiply the remaining students by 9/10 to find the amount of non-sophomores opposed to rock climbing
2250 * 9/10 =2025
Add the amount of sophomores and non-sophomores opposed to rock climbing
810 + 2025 =2835
The amount of students in favor of rock climbing would be
3600 - 2835 =765
