Answer:
7.5 hours (7 hours and 30 minutes)
Step-by-step explanation:
ok Let's start with 64km/h.
1.6 km=1 mile,
64÷1.6=40miles
so 64km/h changes into 40miles/hour.
Zebras's round trip =300miles,
300/40=7.5
so answer is 7.5 hours.
V=s³
SA=6s²
sub 2 for s
V=2³=8 cubic inches
SA=6(2²)=6(4)=24 square inches
Three examples are (9, 1), (9, -5), and (9, 3.2).
1) 6x-7y=-11
2) x=-2
3) y=-4x+1
4) y-5=3(x-1)
