Answer:
Bob = 6km/h, Joe = 4km/h
Step-by-step explanation:
Bob walked 6km/h after 3 hours = 18 km
Joe walked 4km/h after 3 hours = 12 km
Finally, their distance is 30 km.
Answer: Choice A) 90
The upper quartile, aka the third quartile (Q3), is visually represented by the right-side edge of the box, which is at 90 on the number line.
8 x 615 is 4920.
615
x. 8
______
put a 4 above the one and a 1 above the 6.
208 + 10x = 36x
208 = 36x - 10x
208 = 26x
208/26 = x
8 = x......so she must sell 8 purses to break even
So you make your equation 4x+20+40=180.
Add like terms and get 4x+60=180.
Subtract 60 from both sides, get 4x=120.
Divide boths sides by 4, get your answer of x=30.
Hope this helps
