y = 7/6.....................
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
False... a ratio equivalent to 2:5 is 4:10
2/5 × 2/2 = 4/10
Answer:
yes
Step-by-step explanation:
6 -2 = 4
4 - 3 = 1
1 - .80 = .20
Speed = distance ÷ time so it's probably
35÷120=0.291 or 7/24 miles per hour
