The awnser is D but could also maybe be B
Answer:
Step-by-step explanation:
you have to add all the fractions to find the perimeter
10 1/7+10 1/7= 20 2/7 (width)
20 2/7+35 3/7(length) =55 5/7
12 2/7+12 2/7=24 4/7
55 5/7+24 4/7= 79 9/7=80 2/7
80 2/7+ 15 3/14+ 24 1/14= 562/7+ 213/14+337/14= (1124+213+337)/14
=1674/14=119 8/14= 119 4/7
Answer:
19y-9
Step-by-step explanation:
apply distributive property
-3(-4y)-3 x 3 + 7y
12y - 3 x 3 + 7y
12y - 9 + 7y
add 12y to 7y
19y-9
A.450.80
Multiply 40x9.80=392
Take 1/2 of 9.80 that equal 4.90
4.90 plus 9.80 $14.70x4=58.80
$58.80 plus 392 equals 450.80
