Answer:
see below
Step-by-step explanation:
10 + 15k
Factor out the greatest common factor 5
5( 2+3k)
Rewriting
5(3k+2)
Rami is correct if a=2 then his expression is 5(3k+2)
Kenneth
yk+6+8k+4
Add the terms together
k(y+8) + 10
If y =7 then Kenneth is correct otherwise he is incorrect
Answer: the possible numbers of hours Susan could rent the boat is at most 5 hours
Step-by-step explanation:
Let x represent the number of hours
for which Susan could rent the boat.
The boat costs $7 per hour. This means that the cost of renting the boat for x hours is 7x.
Susan has a discount coupon for $3 off. This means that the total amount that she would pay for x hours is 7x - 3
Susan wants to rent a boat and spend at most $32. This would be expressed as
7x - 3 ≤ 32
7x ≤ 32 + 3
7x ≤ 35
x ≤ 35/7
x ≤ 5
Answer:
42%
Step-by-step explanation:
Well, we can rule out the football game. No matter what, it will be over 25$.
Not every dinner and activity will be under 25$, so it cant be 50% or 71%.
5% seems too low.
The answer is x=3.6 or 3 3/5.
First we convert the decimal answer to a fraction; 0.9 is read as "nine tenths," so the corresponding fraction is 9/10:
1 5/6 - (x - 7/12) + 2 1/12 = 9/10
Now we find a common denominator. The first thing that 6, 12 and 10 will all divide into is 60:
1 50/60 - (x - 35/60) + 2 5/60 = 54/60
Distributing the negative, we have:
1 50/60 - x + 35/60 + 2 5/60 = 54/60
Combining like terms, we have:
-x + 4 30/60 = 54/60
Subtracting 4 30/60 from each side, we have:
-x + 4 30/60 - 4 30/60 = 54/60 - 4 30/60
-x = -3 36/60
Divide both sides by -1:
-x/-1 = (-3 36/60)/-1
x = 3 36/60 = 3 3/5 = 3.6
