Hi!

In math, anything that is just grouped together with a bunch of different numbers, operators, or symbols is an expression.

By numbers, I mean your usual 1, 2, 3, 4, 5, 6, 7, 8, 9, etc.

By operators, I mean the operators we use to do calculations with. This will be multiplication, division, addition, and subtraction.

By symbols, I just mean any ol' symbol we can shove in there. This can be pi or stuff such as the actual symbols for our operators. (*, /, +, -). Some more examples would be parentheses and inequality symbols.

So, let's make our own expression.

5 + 9x - (-2x)^2 is in fact an expression! We have numbers, operators, and some symbols. 

Also, note that variables are really common in expressions. Don't let them mess you up. 

With this new found knowledge, you can answer this question on your own! 

Hopefully, this helps! =)

Ryan has a bank account balance of --$17.62. As soon as he realizes this, he deposits $26.50 in the account. What is Ryan's bank
Andrews [41]

The final bank balance is the sum of the initial balance and the amount of deposit made, hence amount in Ryan's account after the deposit will be $8.88

Initial bank balance = - $17.62

Amount deposited = $26.50

<u>Final balance in account will be</u> :

  • Initial balance + Amount of deposit made

  • (-17.62) + $26.50 = $8.88

Therefore, the amount in Ryan's bank account after the deposit is made will be $8.88
