13x-(3)(6)z
13x+-18z
=13x-18z
The book has 100+44=144 pages.
She spent 2+1=3 hours on reading = 3*60=180 minutes
The "speed" will be 144/180 = 0.8 pages per minute
Answer:
Step-by-step explanation:
2/Sin(105) = c / sin(15)
2 * sin(15) = c * sin(105) Divide by Sin(105)
2 * sin(15)/Sin(105) = c
2 * 0.2679 = c
c = 0.539
c = 0.5
Answer:
Okay, so. What I'd do is this.

Then I'd combine like terms.
So:

Once you've got 6x, you subtract 6 from 180.

Now all that's left to do is divide each side by 6 to get x.
X should be 29.
Step-by-step explanation:
You know that adding the equations will give you 180 because you know they're supplementary.
