Answer: it will take 4 months for the amount to be the same and the amount would be $95
Step-by-step explanation:
Let x represent the number if months it will take for the two accounts have the same amount of money.
Christiana opened her account with $55 and plans to deposit $10 every month. This means that the amount that in the account after x months would be
10x + 55
Marlena opened her account with $35 and plans to deposit $15 every month. This means that the amount that in the account after x months would be
15x + 35
For the amount in the accounts to be the same, the number of months would be
15x + 35 = 10x + 55
15x - 10x = 55 - 35
5x = 20
x = 20/5
x = 4
The amount would be
15 × 4 + 35
= 60 + 35
= $95
Answer:
Step-by-step explanation:
Since there aren't any like terms, the answer would be:
Hope this helps!
We'll have to repeatedly square both sides of the equation, in order to get rid of the square roots. Squaring a first time yields
Move the 19 to the right hand side:
And square again:
Square one last time:
Let's check the solutions: all these squaring might have created external solutions:
So, 
is a feasible solution.
