A) 11.5x + 1 = 94
This is because 5.5x + 6x equals 11.5x and 2.5 - 1.5 = 1.

B) x = 8
11.5x + 1 = 94
-1 -1
11.5x = 93
93/11.5 = 8

C) 42.5 by 50.5
5.5(8) - 1.5 = 42.5
6(8) + 2.5 = 50.5

Is this correct?!!! Pls help

7 - 5n = 42

- 5n = 35

n =  - 7

Since a negative times a positive makes a negative you can change your equation to 7 - 5n=42. You can now subtract 7 from both sides to get -5n = 35. Next get divide -5 on both sides giving you n = -7.

Joshua walked 14 feet down the hall of his house to get the door he continued in a straight line out the door and across the yar
AleksandrR [38]

Answer:

Joshua walked 48 feet in total.

Step-by-step explanation:

To find the total distance we need to sum every distance that he walked. We have:

- First: Joshua walked down the hall to the door = 14 feet

- Second: He continued in a straight line out the door and across the yard to the mailbox = 24 feet

- Third: He came straight back across the yard and stopped to pet his dog = 10 feet

Hence, the total distance is:

d_{T} = d_{1} + d_{2} + d_{3} = 14 ft + 24 ft + 10 ft = 48 ft

Therefore, Joshua walked 48 feet in total.

I hope it helps you!
