Answer:
3/7
Step-by-step explanation:
Probability a turban is lent = total number of turbans lent / total number of hats lent
total number of hats lent = 6 + 3 + 3 + 2 = 14
6/14
To transform to the simplest form. divide both the numerator and the denominator by 2= 3/7
For the first one its a slope of -2/3
The second one is 4/5
and the third one is -1/7
Answer:
35/12
Step-by-step explanation:
2 1/2 is 5/2
1 1/6 is 7/6
Multiply these together to get (5*7)/(2*6) or 35/12.
Let X = pounds of Bermuda grass needed.
(20 pounds bahia grass x $6.30) + ( X x $3.65) = (20 +X) x $4.90
Simplify:
126 + 3.65X = 98 + 4.90X
Subtract 3.65X from each side:
126 = 98 + 1.25X
Subtract 98 from each side:
28 = 1.25X
Divide both sides by 1.25
X = 28 / 1.25
X = 22.4 pounds required.
By definition we have the following equation:
t = d / v
Where,
t: time
d: distance
v: speed
For this case we have:
d / 30 + d / 4 = 17
Rewriting we have:
2d + 15d = 17 (60)
17d = 17 (60)
d = 60 mi
Then, the walking time is
t = d / v
t = 60/4
t = 15 hours
Answer:
She walked
t = 15 hours
