Q
Hello!
ANSWER
The painting would cost $387.45.
____________________________________________________________
EXPLANATION
2' 3" = 27"
3' 5" = 41"
Multiply the length by the width (in inches) of the painting.
27 * 41 = 1107
We now know that the area of the painting is 1107 Next, multiply the cost per square inch (0.35) by the total amount of square inches (1107).
.35 * 1107 = 387.45
Answer:
width of the rectangle=x=4in and length of the rectangle=11in
Step-by-step explanation:
Let the width of the rectangle be x, then according to the question, length is one less than three times its width that is l=3x-1.
Now, width=b=x and length=l=3x-1, thus
Perimeter of the rectangle= 2(l+b)

Thus, width of the rectangle=x=4in and length of the rectangle=l=3x-1=3(4)-1=12-1=11in.
Answer:
x=(k+3)/y
Step-by-step explanation
First, we simplify by adding 3 to both sides of the equation
xy-3+3=k+3
Now it's xy=k+3
To get x we divide both sides by y
So x=(k+3)/y
