Answer:
2 pieces
Step-by-step explanation:
Given
Required
Calculate the number of pieces
To do this, we have to divide the length of the wood by the length of each piece.
Represent this with x
Convert mixed numbers to improper fraction
Change division to multiplication

top left: speed = 2.7 miles per hour = 2.7 MPH
top right: speed = 0 miles per hour = 0 MPH
bottom left: speed = 4 miles per hour = 4 mi/h
bottom right: speed = 2 miles per hour = 2 mi/h
and so, the fastest is bottom left. And pay attention in class! i'm in highschool and Iearned this in 6th grade!
Step-by-step explanation:
key: speed= distance/time
distance= speedxtime
time=distance/speed
top left: 8/3= 2.66667 MPH= 2.7 MPH
top right: 0/8= 0 MPH= 0 MPH
bottom left: 8/2= 4 MPH= 4 MPH
bottom right: 8/4= 2 MPH= 2 MPH
You could do x=81 with the little line on the top (represents the number going on forever, and example is 0.818181818181818181818181818818181818 etc.)
Answer:
r=2
Step-by-step explanation:
r + 8 r + 11 = 29
( 1 + 8 ) r + 11 = 29 9 r + 11 = 29
Now we can isolate and solve for r while always keeping the equation balanced: First, subtract 11 from each side of the equation:
9 r + 11 − 11 = 29 − 11
9 r + 0 = 18
9 r = 18
Now we can divide each side of the equation by 9 to get
r : 9 over 9 = 18 under 9
1 r = 2
r = 2
