Answer:
D. $53.76.
Step-by-step explanation:
20% = 0.20 as a decimal.
Price before Sales Tax = 64 - 0.20*64
= $51.20
Adding 5% sales tax we get
52.20 + 0.05*51.20
= $53.76 (answer).
Answer:
I believe that the answer is 95 meters.
Explanation:
Okay, so to solve this question, you must know the formula to solve for the area of a rectangle/square.
<em>Area of a rectangle/square - </em><em>l x w</em>
<em />
In this question, you can see the the width (72 m) and the area (6840 m²) is already given. What you can do in this situation is to use the opposite operator (division) to solve for the length of the rectangular field.
<em>6840 ÷ 72 = </em><em>95</em>
You can always double check to see if the number is correct.
<em>A = l x w</em>
<em>= 72 m x 95 m</em>
<em>= </em><em>6840 m</em>²
Really hope this helped. :)

Answer:
x = -2, proven below.
Step-by-step explanation:
3x + 7 + 2(4x+1) = 3(x-1) - 4
3x + 7 + 8x + 2 = 3x - 3 - 4
9 + 11x = 3x - 7
16 + 11x = 3x
16 = - 8x
-2 = x
