Complete the real-world situation that could be modeled by the equation 110 − 4x = 130 − 8x. xavier has $110 in his lunch account. he spends $ for lunch each day. zack has $ in his lunch account. he spends $ each day. after how many days will the boys have the same amount of money in their accounts?

x = 5

Step-by-step explanation:

Pay attention to the equation here, because it's all you'll need to solve the problem. Look at the numbers tied to our variable x; 4 and 8. We can assume that x is the number of days and these numbers are what Xavier and Zack spend each day for lunch.

They already told you that Xavier has $110 in his bank account, so we can assume that all the information we need for him is on the left side of the equation (110 - 4x). Being that x represents the number of days and the number tied to it is the amount spent on lunch, we can see that Xavier spends $4 for lunch every day.

The right side of the equation is for Zack. Zack has $130 in his bank account and spends $8 for lunch every day.

Now to solve for our equation:

110 - 4x = 130 - 8x

And so, we can see that x equals five. So, Xavier and Zack will have the same amount in their accounts after five days. To check:

110 - 4(5) = 130 - 8(5)

110 - 20 = 130 - 40

90 = 90

$12. that is my answer.

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
