Answer & Step-by-step explanation:
number of Dave's coins = number of Zack's coins + 5
The question is asking to find the difference in prices paid (thus "<em>more</em>"), completely unrelated to the number of coins Zack bought as these two numbers are independent of one another. The difference in price can be found by simply multiplying the cost of one coin by 5.
First, you much find out how many houses are deliverd in 1 hour.
130/2.5=52
So 52 houses are delivered in 1 hour. Now, divide that by 312.
312/52=6
It would take 6 hours to deliver 312 houses.
5(-2)^3 5(-2) is -10 to the power of 3 is -1000
Answer
y=−3/5x−23/5
given the slope m of a line then the slope of a line
perpendicular to it is
7.5x18.74= 140.55 is the correct answer
