Answer:
The expression is 10t = 65
Step-by-step explanation:
At the point where the local train and the express train meet, both trains would have travelled an equal distance.
A local train leaves the station in Springfield traveling toward New York City at a constant rate of 55 mph.
Let t represent the time it spent in travelling a given distance.
Distance = speed × time
Therefore,
Distance travelled by the local train is 55 × t = 55t
The express train headed for New York City on the same route leaves the station 1 hour later. The rate of the express train is 65 mph. It means that total time spent travelling the same distance as the local train is t - 1
Therefore, distance travelled is
65(t - 1)
Since the distance travelled is the same, therefore,
55t = 65t - 65
65t - 55t = 65
10t = 65

<h2>
Explanation:</h2>
For inequalities, "a is no more than b" can be written as:

Here we know Candace that can spend no more than $52 before tax. She can spend a certain amount of money in both Dark Roast coffee and Morning Blend coffee. So she spends:
- 2 pounds of Morning Blend coffee.
- p pounds of Dark Roast coffee
Therefore:
<u>Amount of money for Morning Blend coffee:</u>

<u>Amount of money for Dark Roast coffee:</u>

So the total amount of money:

Finally, the inequality becomes:

Besides, in order to know how many pounds she can spend let's solve for p:

So she can spend less that 4.13 pounds.
