-8=2-4y
-10=-4y
y=5/2 or 2 1/2 or 2.5
Answer: 74 ft
12+12+15+15= 74
Perimeter is the distance around sometime
11.2 x 11 x 8 is 985.6
so uh- yeah i hope that helped lol
Answer:
$1.90
Step-by-step explanation:
Divide 5.7 by 3 to get your answer.
= 1.9
Let
x---------> the length of the first piece
y---------> the length of the second piece
z---------> the length of the third piece
we know that
x+y+z=72 -------> equation 1
y=x+6 -----> solve for x
x=y-6 -------> equation 2
z=6+y -------> equation 3
substitute equation 2 and equation 3 in equation 1
[y-6]+y+[6+y]=72
3y=72
y=(72/3)=24 in
<u>Find the value of x</u>
x=y-6 -------> equation 2
x=24-6=18 in
<u>Find the value of z</u>
z=6+y -------> equation 3
z=6+24=30 in
therefore
<u>the answer is</u>
the length of the first piece is 18 in
the length of the second piece 24 in
the length of the third piece is 30 in
