Reese had $42 in his pocket orl Sunday night. He spent $6.50 every day for lunch.
Which of the following equations best describes the relationship between d, the
number of days since Sunday, and m, the amount of money remaining?
The required equation is m = 42 - 6.50d which is the correct answer would be an option (C).
What is the Linear equation?A linear equation is defined as an equation in which the highest power of the variable is always one.
We have been given that Reese had $42 in his pocket on Sunday night. He spent $6.50 every day for lunch.
Let d represents the number of days since Sunday, and m represents the amount of money remaining
Reese has 42 total and it subtracts by 6.50$ every day
According to the given question,
The linear equation would be as
m = 42 - 6.50d
The above model equation is the relationship between d, the number of days since Sunday, and m, the amount of money remaining
Therefore, the required equation is m = 42 - 6.50d.

A toy Jeep is 12 1/2 inches long, while an actual jeep measures 18 3/4feet long What is the value of the ratio of the length of the toy jeep to the length of the actual jeep? What does the ratio mean in this situation?
Answer:
1:18
Step-by-step explanation:
Given that,
Length of a toy jeep = 12 1/2 inches = 25/2 inches
Length of an actual jeep = 18 3/4 feet = 75/4 feet
1 foot = 12 inches
75/4 feet = 225 inches
We need to find the ratio of the length of the toy jeep to the length of the actual jeep.
[tex]R=\dfrac{\dfrac{25}{2}}{225}\\\\=\dfrac{1}{18}[/tex]
So, the required ratio is 1:18.
