Answer:
50
Step-by-step explanation:
We know that Lucy can type 52 more words than Jim (who types 548 words in 12 minutes).
Now that we know Lucy can type 600 words in 12 minutes, how many does she type per minute? To solve, we simply divide 600 by 12.
Lucy can types 50 words per minute.
Good Morning. okay? To solve this problem is very simple, it is only using a system.
20c + 10b = 800
10c + 30b = 900
Multiply the second equation by -2.
20c + 10b = 800
-20c - 60b = -1800
Now it is only to add the two equations.
0 - 50b = -1000
b = -1000/-50
b = 20
Now that we have discovered the 'b' we will substitue in the equation.
10c + 30 . 20 = 900
10c + 600 = 900
10c = 300
c = 300/10
c = 30
b=20 c=30
ok? thanks, i hope i have helped.
