A)
3t = 7k/13 - 17
3t + 17 = 7k/13
13*(3t + 17) = 7k
7k = 13*(3t + 17)
7k = 39t + 221
k = (39t + 221) / 7
b)
7k = 4k/3t - 11t
11t = 4k/3t - 7k LCM = 3t
11t = (4k - 21kt) / 3t
11t*3t = (4k - 21kt)
33t² = k(4 - 21t)
33t² /(4 - 21t) = k
k = 33t² /(4 - 21t)
I hope this helps.
Answer:
no
Step-by-step explanation:
you cannot divide zero into two equal parts because there is nothing there to start. Since Pablo has no candy, he cannot divide it into two piles because there isn't anything to divide.
R = 10a - 20
ur revenue totaled 110...so R = 110
110 = 10a - 20
110 + 20 = 10a
130 = 10a
130/10 = a
13 = a <== so u spent $13 on advertising
