Answer:
the width is 7 inches
Step-by-step explanation:
A = l * w

Answer:
The bookkeeper already has a balance of 83.92. She collects 76.75 so that's 83.92+76.75 which equals to 160.67. Then she pays out 38.58 so that's a deduction to what she already has. 160.67-38.58=122.09.
SO the bookkeeper has $122.09 left.
Answer:
2-3x=-6
We simplify the equation to the form, which is simple to understand
2-3x=-6
We move all terms containing x to the left and all other terms to the right.
-3x=-6-2
We simplify left and right side of the equation.
-3x=-8
We divide both sides of the equation by -3 to get x.
x=2.66666666667
God bless you and have a beautiful rest of the day!
