Answer:
20s=m
Step-by-step explanation:
I really don't understand it that well but all that I can is that s can represent students that went on the trip, and each student's ticket cost is 20$, so 20*s=20s, but we are taking m as the total money collected, so we can end up saying that 20s=m, hope u understood :)
Answer:
Its b
Step-by-step explanation:
490 please trust me
A) 5s + 7p = 43 nanoseconds
B) 4s + 6p = 36 nanoseconds
Multiply equation A) by 4 and equation B) by -5
A) 20s + 28p = 172
B) -20s -30p = -180 Adding both equations
-2p = -8
EACH product requires 4 nanseconds
Computing SUM
A) 20s + 28*4 = 172
A) 20s + 112 = 172
A) 20s = 60
SUM = 3 nanosecond
How many months did it take then I can calculate each months wage increase
