Answer:
The first question provided (question 11)
The answer is $118.00
The second question provided (question 12)
The answer is 20 seconds
Step-by-step explanation:
The first question provided (question 11)
The equation 5a + 3c is provided to determine the cost of a catering event, where a is the number of adults and c is the number of children.
It is stated that there are 17 adults and 11 children attending an event.
You can substitute in the 17 adults in place of a and the 11 children in place of c.
This will leave you with 5(17) + 3(11).
If you simplify you will get 85 + 33, which is equal to 118
Therefore, the answer is $118.00.
The second question provided (question 12)
The equation s = 5w is provided to determine how far behind a clock is after a certain amount of time, where s is seconds behind and w is the number of weeks sice the clock was last set.
You are given the clock was set 4 weeks ago.
You can subsitute the 4 weeks into the equation in place of variable w.
This leaves you with s = 5(4).
Simplifying this further, you will get s = 20.
Therefore, the clock is 20 seconds behind.
