Answer:
Multiple
Step-by-step explanation:
You put the equation in slope intercept form, therefore, the solutions are the entire line!
Every point on the line can be considered a solution.
The next two term in patterns is below
3,6,5,10,9,18,17,34,33,66
We must multiply and divide before adding and subtracting here. Working from left to right, we get:
8 + 15 - 5 = ?
8 + 10 = ?
18 (answer)
8090kg-4854kg=decrease in kg ----- find the difference
3236=decrease in kg
3236kg/8090kg=percent decrease ----- decrease/original amount
0.4= percent decrease ------ percent decrease in decimal form
0.4*100=percent decrease ------ multiply by 100 to get percent form
40% decrease
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
