Answer:
p=30
Step-by-step explanation:
First, you need to subtract 10 from both sides to get 1/2p=25. You do this just because simplifying is much easier.
Then, you need to isolate p, so you divide 1/2 by both sides, which is the same thing as multiplying by 2. 1/2*2p=15*2.
Simplifying, you get p=30.
B.) 15d+100
100 is a sure value as he earned it
We do not know how many days he worked, therefore variable d is used to represent d amount of days, but we do know he recieved $15 for everyday that he did work
The number of the day is 60 because the LCM is 30
Answer:
The bus is late 4 times in March.
Step-by-step explanation:
Solving this problem is very easy, using this formula:
20(0.2) = times late in March
(The 0.2 is the decimal form of 20%)
This is equal to 4, the times in March when the bus was late.
I believe the answer is x² + 3x - 10.
I found this on Yahoo Answers so it isn't my own work.
