Try this first :) Let me know what you come up with :)
Answer: x = 38.4
Step-by-step explanation:
7-x/3 = -1-x/8
1. Add 1 to both sides
8-x/3 = -x/8
2. Add x/3 to both sides
8 = x/3 - x/8
3. Multiply x/3 by 8/8 and x/8 by 3/3 to get the same number under the quotient
8 = 8x/24 - 3x/24
4. calculate the difference between 8x/24 - 3x/24
8 = 5x/24
5. Multiply both sides by 24/5, and there is the answer
38.4 = x
First we have to find the perimeter. Which is for rectangles 2(l+w)
that means the perimeter is 75.84 ft
each slat is apparently half a foot which would be 0.5ft
then you simply divide 0.5 from 75.84 and round it to the nearest whole number.
