3x-12=60°
3x-12+(12)=60+(12)
3x=72
3x÷(3)=60÷(3)
x=24
Same with me people these days lol but it wasn't a science question
Answer:
(50,-30)
Step-by-step explanation:
Reflecting a point across the y axis is just like flipping a page on a book. The x coordinate is flipped and the y coordinate stays the same.
30 min = 30/60 hr = 0.5 hr
d = rt
100 = r*0.5
100/0.5 = r
200 = r
r = 200 mph.
We know that Rate = distance/time
(30 minutes is .5 hour)
Rate=100 mile/.5 hour
Divide and we get:
Rate=200 MPH
(Hint: MPH is Miles per Hour---Per means "for each")
Make sense?
The number is x
x of 55% = 94
x * (55/100) = 94
x = 9400 / 55
x = 170.91
