1. To find how much cardboard he needs to paint you need to find the area of the cardboard which is length times width. So in this case, it would be 16 1/3 feet times 6 feet. Or 49/3 times 6/1. This gives you 294/3 or 98 feet.
2. To find this you would divide the total area by how much area each bottle covers to find how many bottles you need. 98 divided by 30 is 98/30 which reduces to 49/15 or 3 4/15. Since you can’t have 4/15 of a bottle, you’d round up to 5 bottles of paint.
Set the two expressions equal to each other.
7x + 3 = 9x
Simplify, isolate the x, subtract 7x from both sides
7x (-7x) + 3 = 9x (-7x)
3 = 2x
Set the equation = 0, subtract 3 from both sides
3 (-3) = 2x (-3)
0 = 2x - 3
2x - 3, or D, should be your answer
hope this helps
