Answer:
Part A: 100
Part B: 625
Step-by-step explanation:
Part A equation: 25 x 4 = 100
Part B equation: 25 x 25 = 625
H=10+4x
flat rate of ten plus how ever many hours you've had it times 4
I think that the answer should be around 2.55
Answer:
Gregory will catch up Efren after 26 minutes 40 seconds.
Explanation:
Distance traveled = Speed x Time
Speed of Efren = 4 mi/h
Speed of Gregory = 8.5 mi/h
Let the time of catch up be t hours.
Time of journey of Efren before catch up = (t+0.5)hours, since he starts before half hour.
Distance traveled by Efren = 4 x (t+0.5) miles
Time of journey of Gregory before catch up = t hours.
Distance traveled by Gregory = 8.5 x t miles
If they catch up the distance traveled by them is same, so equating both distances.
4 x (t+0.5) = 8.5 x t
4.5t = 2
t = 0.44 hours =26.67 minutes = 26 minutes 40 seconds.
So Gregory will catch up Efren after 26 minutes 40 seconds.
Solution:
16.
Given: 3n+5/7
We can rewrite it as:
3n+5/7 = 3n/7 + 5/7
The sum of two terms is 3n/7 + 5/7.
17.
Given: 9p-6/3
We can rewrite it as:
9p-6/3 = 9p/3 - 6/3
= 3p - 2
The difference of two terms is 3n/7 + 5/7.
18.
Given: Length = -2n+17
Width = 24
Area = length * Width
= (-2n + 17) * 24
= -48n + 408
Hence, the simplest form is -48n + 408.
