Answer:
simplify: 2.5 =(y+5)
reorder the terms: 2.5y=(5+y)
remove the parenthesis: 2.5y=5+y
solving: 2.5y=5+y
move all terms containing y to the left, all other terms to the right.
add -1y to each side of the equation
2.5y+-1y=5+y+-1y
combine like terms 2.5y+-1y=1.5y
1.5y=5+y+-1y
combine like terms: y+-1y=0
1.5y=5+0
1.5y=5
divide each side by 1.5
y=3.333333333
simplifying
y=3.333333333

Step-by-step explanation:
Answer:
t^2+4
Step-by-step explanation:
The perimeter of the table can be given by the equation 2l+2w, and we know the length is 2t-3, meaning 2(2t-3)+2w=2t^2+4t+2, as we know 2t^2+4t+2 is the perimeter. Simplifying we get:
4t-6+2w=2t^2+4t+2
4t+2w=2t^2+4t+8
2w=2t^2+8
w=t^2+4
This means that the table's width is t^2+4
"One rotation" would be the circumference of the wheel, which is
C = 2*pi*r, or (here) C = 2*pi*(8 inches) = 16*pi inches.
1 ft
Convert this to feet: 16*pi inches times ---------------
12 inches
Here "inches" cancels out and you are left with (4/3)pi ft.
So, one rotation of the wheel moves you and your bike forward (4/3)pi ft.
Divide this into 700 feet:
700 ft 2100
------------- = --------- rotations = 525 rotations (answer)
(4/3) pi ft 4
