Answer:
F
Step-by-step explanation:
8x +9 = 6x + 21 where x = number of chairs in each row
2x=12
x=6
sub back into original equation 8 x 6 + 9 =57 chairs
Properties can help you divide because if you didn't follow them we would have incorrect answers and would be very held back in science and mathematics
Answer:
<u>The correct answer is C. 6, 8 and 9 inches.</u>
Step-by-step explanation:
1. Let's review all the information provided for answering the questions properly:
Length of the sides of the triangle = 12 feet, 16 feet and 18 feet.
Scale used : 1 inch = 2 feet.
2. How long should the sides of the triangle be in inches?
For calculating the length of the sides of the triangle in the draw, we use the scale this way:
1st Side = 12 feet
12 feet/2 = 6 inches
2nd Side = 16 feet
16 feet/2 = 8 inches
3rd Side = 18 feet
18 feet/2 = 9 inches
<u>The correct answer is C. 6, 8 and 9 </u>
