Since the formula for finding distance is d=r(t), it would be d=15(3). So the distance would be 45 miles in 3 hours.
The answer for your question is 10
DEFINITIONS
Algebraic word problems are questions that require translating sentences to equations. The equations we need to write will only involve basic arithmetic operations and a single variable. Usually, the variable represents an unknown quantity in a real-life scenario.
SOLUTION STEPS
Step 1: Name the variable.
The variable, in this case, is n.
Step 2: Identify the mathematical operation in this mathematical statement.
Product refers to multiplication. Therefore, we will be using the multiplication operation for the question.
Step 3: Write out the algebraic expression for the statement: "The product of 7 and a number".
Since we are representing the number with n, the product of n and 7 will be given to be:

ANSWER:
The correct option is OPTION B.
Answer:
An appropriate method is to generate a simple random sample of all single-family homes in the city or a stratified random sample by taking a simple random sample from each of the ten district neighborhoods.
Step-by-step explanation:
Since, the city is very large and it is divided into ten districts. So, collecting sample from one district or any particular are did not give the correct estimate of whole city. So, the appropriate method to collect sample is taking the sample randomly from each district and this type of sampling method is called Stratified Sampling.
