Answer:
13 bags
Step-by-step explanation:
1: If he has 6 3/4 lbs to start with, this is 6.75 lbs, as 3/4 = 0.75.
2: He wants the new bags to be 1/2 lb, which is 0.5 lbs.
3: If we divide 6.75 by 0.5, we get the exact number of bags he could have - 13.5.
4: However, the bags must be full, so we have to disregard that extra 0.5 bags, and say he can completely fill 13 bags.
Hope this helps! Let me know if you have any questions :)
Answer:
Perimeter of ABCD = <u>56 units</u>
Perimeter of WXYZ = <u>140 units</u>
Step-by-step explanation:
<u>To find the perimeter of ABCD, find the sum of all sides</u>
18 + 18 + 10 + 10 = 56
<u>To find the side lengths of WXYZ, use the equation:</u> 
45/18 = 2.5
<em>You can also cross multiply to find the missing side lengths, but I'll show you this other way...</em>
<u>Multiply the pre-image side lengths by 2.5</u>
18 × 2.5 = 45
10 × 2.5 = 25
<em>45 and 25 of the new side length of WXYZ</em>
<em />
<u>To find the perimeter of WXYZ, find the sum of all sides.</u>
45 + 45 + 25 + 25 = 140
WX = 45, XY = 25, YZ = 45, ZW = 25
