Oksanka [162]
A deposit adds to the amount of a checking account.
So a deposit of $120.75 is + 120.75.
A withdraw subtracts from the amount of a checking account.
So a withdraw of $185.90 is - 185.90.

If the original amount is $425.82, you would simply add the amount of the deposit then subtract the amount of the withdraw.

425.82 + 120.75 - 185.90 = 360.67

So the amount in Christian's checking account after <span>a deposit if $120.75 and withdrawal of $185.90 is $360.67.

Answer:
$360.67

Hope this helps! :)

The area of the pentagon is = 31.5

Step-by-step explanation:

<em>First, we determine the perimeter of the "Pentagon" drawn in the attachment:</em>

p=4+4+4+4.5+4.5=21

<em>Now, we'll check the formula for pentagons:</em>

a=\frac{perimeter x apothem}{2}

<em>we calculate the apothem by placing a 90° angle in one of the sides of the shape. It is equal to:</em>

apothem=3

<em>then, we can substitute the values in the formula</em>

a=\frac{21(perimeter) x 3(apothem)}{2} =\frac{63}{2} =31 \frac{1}{2} or 31.5
