Answer: the number of yards that art bought is 20 3/20 yards
Step-by-step explanation:
Art bought 7 1/4 yd and 12 9/10 yd for two car projects. We would convert both measurements from mixed fraction to improper fraction before adding.
Converting 7 1/4 yd to improper fraction, it becomes 29/4
Converting 12 9/10 yd to improper fraction, it becomes 129/10 yd
Adding both measurements, it becomes
29/4 + 129/10 = (145 + 258)/20 = 403/20yds
Converting to mixed fraction, it becomes
20 3/20 yards

Step-by-step explanation:
Step-by-step explanation:
P = 6+6+5x-3 + 5x -3 = 10x+6
A = 6(5x-3) = 30x -18
The width is 1/3 of the length. You can tell that off of the ratio.
To find the perimeter of a rectangle, you have to use the equation:
2L+2W=136
W=1/3L; We can plug that in for W.
2L+2(1/3L)=136
2L+2/3L=136
2 2/3L=136
136÷2 2/3= 51=L
The length is 51 ft. We need to make sure by finding the width and making sure the perimeter is equal to 136.
3:1
51:17
The width is 17 ft. 17+17+51+51
34+102=136
So, the length is 51 ft.
