Distance = Rate x time
Time = 4.5 hours
Rate = 70 miles per hour
Distance = 70 x 4.5 = 315 miles.
Answer:
sorry I don't know how to do the last one.
Answer:
(3x-2)(X+4)
X=2/3,-4
Step-by-step explanation:
3x^2 + 10x = 8
3x^2+12x-2x-8=0
3x(X+4)-2(X+4)=0
(3x-2)(X+4)=0
X=2/3,-4
So the solution is 2/3,-4
Answer:
30
Step-by-step explanation:
Ratios always remain proportionate. In this case, the simplified ratio has 1 red car. The question tells us that there are 6 cars. 6 is 6 times bigger than 1; thus showing that the ratio has increased by a factor of 6. If one side of the ratio increases by a factor of 6, then the other side must also increase by a factor of 6. Since 5*6=30, there must be 30 employees that own a black car.
