you cant solve it
Step-by-step explanation:
the answer would still be 3x^2
Answer:
Don't worry,no one will be subtracted but all will be added.
Yes they will be equal at some point. Although Marc has more miles on his car at the current moment, Elena is adding miles at a higher rate.
Elena's car: 7000 + 21000t
Marc's car: 20000 + 11000t
To find at what time t they are equal, set these two expressions equal to each other and solve for t.
7000 + 21000t = 20000 + 11000t
13000 = 10000t
t = 1.3 years from now
1 kilogram is around 2.2 pounds so just multiply the pounds by 2.2
3(20 - b) = 36
60 - 3b = 36
-3b = 36 - 60
-3b = - 24
b = -24/-3
b = 8 <==
