It would be (2,1)
y=-2*2+5
y=-4+5
y=1
I think it's c) 5 because the first pentagon is 5 and then decreases to a 1. i divided it and i got 5. it decreased by 5.
4s+7a=861
s+a=168
This can be solved using either elimination or substitution. I am going to use substitution.
Solve s+a=168 for s
s=168-a
Replace 168-a for s in 4s+7a=861
4(168-a)+7a=861
672-4a+7a=861
Solve for a
672+3a=861
3a=189
a=63
Substitute 63 for a in s=168-a
s=168-63=105
So, s=105 student tickets and a=63 adult tickets
Answer:
3) 361/11
4) 51
Step-by-step explanation:
for both problems, they give you the length of the segment so you just add both of the segments equal to the length of the whole segment. then for whatever you find as x, plug it into the equation.
ex. 7x+1+4x-3=42
or
5x-8+7x-12=10x-2
