Answer: 1000 hot dogs and and 1600 sodas were sold.
Step-by-step explanation:
Let x be the number of hot dogs and y be the number of sodas.
Given : The concession stand at an ice hockey rink had receipts of $6200 from selling a total of 2600 sodas and hot dogs.
Each soda sold for $2 and each hot dog sold for $3 .
Then, we have the following system of two linear equations:-

Multiplying 2 on both sides of (1), we get

Now, Eliminate equation (3) from equation (2), we get

Put x=1000 in (1), we get

Hence, 1000 hot dogs and and 1600 sodas were sold.
<h3>Amount of sand craig and Alissa collect together at one time is 1.4 pounds</h3>
<em><u>Solution:</u></em>
Given that,
Craig and Alissa are building a sandcastle on the beach. They each have a bucket
Craig's bucket holds 1/2 pound of sand and Alissa's bucket holds 9/10 pound of sand
Therefore,

<em><u>How much sand can craig Alissa collect together at one time</u></em>
Add both, we get

Thus, amount of sand craig and Alissa collect together at one time is 1.4 pounds
Answer and explanation:
The data we get from counting how many people entering a building in one minute is the sample of the population size. We do this since it would be tedious or not feasible to stand and count one by one how many people enter the building and so we do a good estimate with our one minute sample
Let's assume in one minute, 15 people enter the building and it takes one hour for everyone to enter the building
Population size would be 15*60 minutes= 900 people
The answer is 3(5x+2) i hope this helps you.
