Question

PLEASE HELP ME!!! I'M GIVING 11 POINTS

1. Mara has $640 in her bank account. If she withdraws $30 every month, in how many months will she have $370 remaining in her account

2. Make up an equation that has no solution and explain what that means. (Hint: It has to be a real explanation, not just "it doesn't work").

Answer 1

1. 9

2.

Explanation:

1. Mara has $640 in her bank account, she withdraws $30 each month. We don't know how many months will she withdraw until 370$. Let's write an expression first:

640 - 30x = 370

Now, subtract both sides by 640 to get -270:

-30x = -270

Last, divide both side by -30:

-30x = 270

x = 9

Now, we know she withdraws $30 for 9 months.

2. 2 + 4(3 - 2) = x

This tells us that we do not know the answer until we solve it.

2 + 4(3 - 2) = x

2 + 12 - 8 = x

6 = x

Answer 2

610, 580, 550, 520, 490, 460, 430, 400, 370 It takes 9 months

Explanation:

2: 1.50+x=π This problem is impossible. This is because Pi is a number that goes for infinitiy so there is no answer for x. This also means ∞ can also be an answer.
