Answer:
Your original account balance before you made the deposit is $6
Step-by-step explanation:
Let x = your original account balance.
You triple your account balance by making a deposit. This means
New account balance = 3 × x = 3x
Then you withdraw $28.50 from your bank account. This means that you have $(3x - 28.5) left.
Now your account is overdrawn by $10.50. This means you have withdrawn beyond what you have in your account. Your new account balance is -$10.5. Therefore,
3x - 28.5 = - 10.5
3x = -10.5 + 28.5 = 18
x = 18/3 = 6
Your original account balance before you made the deposit is $6
Answer:

(This is a Quadratic equation in the variable x).
Answer:
A straight angle is an angle of 180 degrees, so it looks like follows
Answer:
A. a + b = 180 is the correct option.
Rectangle (left): A = 9 x 7 = 63
Rectangle (right): A = 2 x 10 = 20
Quarter circle: A = (1/4 x 3.14 x 3^2) = 7.065
A = 63 + 20 + 70.65
A = 90.065 square feet
Hope this helps! :)
