I’m guessing ur trying to use the absolute function where x is positive. It looks like in the picture, but move it down two spaces

Find the value of x.<br><br> RZ = 30<br> SW = 5x - 20
Murrr4er [49]
|RZ|=0.5|SW| therefore 2|RZ|=|SW|.

5x - 20 = 2 · 30

5x - 20 = 60    |add 20 to both sides

5x = 80    |divide both sides by 5

x = 16

1. Evan drove 308 km in the same time that Meghan drove 329 km. If Meghan drove
emmainna [20.7K]

Answer:

Her average speed is 94 km/h

Time taken is 3.5 hours

Step-by-step explanation:

Let Evan’s average speed be x km/h.

now since Meghan drove faster, according to the question, we can say her average speed would be x + 6 km/h

Mathematically, time = distance/speed

so; since time is the same; we have

308/x = 329/(x + 6)

cross multiply

329(x) = 308(x + 6)

329x = 308x + 1848

329x-308x = 1848

21x = 1848

x = 1848/21

x = 88 km/h

Meghan average speed = x + 6 = 88 + 6 = 94 km/h

Time taken would be 329/94 = 3.5 hours

Can someone please explain why x= -2! ASAP!!
bearhunter [10]
Because you add both negative x’s which is -2 and add the -6 in the right side so then it’s -2x=4
Divide and you get x=-2
