Answer:
use a graph paper to find the answers
8a+4s=840
a=s+30
8(s+30)+4s=840
12s+240=840
12s=600
s=50
A=s+30
a=50+30
a=80
The drama play sold 80 adult tickets
You take 69 * 0.35 and then take that total (24.15) so 60-24.15= 35.85 then to find the tax take 35.85*.07=2.51 so your answer is 35.85+2.51=38.36
The factor that is the first one is the most important
Answer:
b=4
Step-by-step explanation:
-14+2b= -2b+2
Add 2b to each side
-14+2b+2b= -2b+2b+2
-14+4b =2
Add 14 to each side
-14+4b+14= 14+2
4b = 16
Divide each side by 4
4b/4 = 16/4
b =4
