Her total cost is $19.50
$3.30 x 3 = $9.90
+
$3.20 x 3 + $9.60
=

Or your answer could be 19.5
(It’s the sum either way.)

Answer: 40 Centimeters per second
Step-by-step explanation:
360/9 = 40
Answer:
no solution
Step-by-step explanation:
1/2(2-4x)+2x=13
We simplify the equation to the form, which is simple to understand
1/2(2-4x)+2x=13
Simplifying:
+ 0.5*(2-4x)+2x=13
Reorder the terms in parentheses
+(+1-2x)+2x=13
Remove unnecessary parentheses
+1-2x+2x=+13
We move all terms containing x to the left and all other terms to the right.
-2x+2x=+13-1
We simplify left and right side of the equation.
0x=+12
0=12
The left and right sides are not equal, therefore there is no solution. This equation is invalid.
