2c+5t=43
c=(43-5t)/2
8c+3t=36 and using c found above in this equation gives you:
4(43-5t)+3t=36
172-20t+3t=36
-17t=-136
t=8, and since c=(43-5t)/2
c=1.5
So a table costs $8.00 to rent and a chair costs $1.50
4 and a half to fill
30 in total minus the ones already used 30 - 18 = 12
A forth of the pages she wants to save which is about 7.5 of the total
12 - 7.5
Means she only has 4.5 pages left to use before she starts using her extra vacation pages
G-(-43)=19
g+43=19
g=19-43
g=-24
B.
The table on the far left
You can tell because every time the x value increases by 1, the y value increases by exactly 1/2 every time
If you put the equation into graphing calculator online or manual, you can get the graph.
