Thanks a Billion!
Could you post what you THINK the answer is for each question? Then you won't be cheating and you can still get help. Also, for the first question, do you have any number assigned to those exponents (ex: x=3)?
wym cheating? this isnt my homework this is my friends homework. I need answers so i could help him do these
1. To find the total number of video games that Ethan and Kyle have, we need to add together the number of video games each of them has.
Let's start with the number of video games that Ethan has, represented by "v".
Now, Kyle has one-third as many video games as Ethan, which can be represented by "(1/3)v".
In addition to that, Kyle also has "m" more video games.
Therefore, the expression to represent the total number of video games that Ethan and Kyle have is:
v + (1/3)v + m
2. To calculate "one-third of x subtracted from two times y", we first need to find one-third of "x", and then subtract it from two times "y".
One-third of "x" can be represented by "(1/3)x".
Next, we multiply "y" by 2, which gives us "2y".
Finally, we subtract "(1/3)x" from "2y" to get the final expression:
2y - (1/3)x
3. Rani plans to save 25% of the money she earned over the weekend and spend the rest.
Let's represent the amount of money Rani earned on Saturday as "x" dollars and the amount she earned on Sunday as "y" dollars.
To calculate the amount of money Rani saves, we need to find 25% of the total amount she earned over the weekend.
The expression to represent the amount of money Rani saves is:
0.25(x + y)
4. Sophie is buying soft drinks for a group of people at the movie theater. The number of people who want each size of drink is not given, but we can represent it using variables.
Let's say the number of people who want large drinks is "L".
The number of people who want medium drinks is "M".
And the number of people who want small drinks is twice the number of people who want medium drinks, so it can be represented as "2M".
The cost of large drinks is $2.50, the cost of medium drinks is $2, and the cost of small drinks is $1.
To calculate the total amount of money Sophie spends on drinks, we need to multiply the cost of each drink by the number of people who want that size and then add them together.
The expression to represent the total amount of money Sophie spends on drinks is:
2.50L + 2M + 2M
Simplifying the expression:
2.50L + 4M
5. To determine how much Evan earned for the month of July, we need to know the number of turtles cared for each week and the amount Evan earns per week per turtle.
Let's represent the number of turtles cared for each week as "t" and the amount Evan earns per week per turtle as $25.
Since Evan earns $25 per week per turtle, we can multiply the number of turtles cared for each week by $25.
To calculate the total amount Evan earned for the month of July, we need to add up the earnings for each week.
The expression to represent the total amount Evan earned for the month of July is:
25t + 25t + 25t + 25t
Simplifying the expression:
100t
