Answer:
3 miles per hour.
Step-by-step explanation:
To get his walking rate in miles per hour, we multiply 1/5 by its reciprocal, 5/1. We also multiply 6/10 by 5/1. This gets us 30/10 of a mile in an hour. We can simplify 30/10 to 3. This means he walks at 3 miles per hour.
The answer is that the slope equals -2.
Explanation:
To find the slope, all you have to do is count how many units the line goes up and right between two points. Between points (-2,4) and (0,0), the lines does up -4 units (the negative means it went down) and right 2. Then, divide the up/down by the left/right, -4/2, in this case, to find the slope. -4/2 is -2. Therefore, the slope is -2.
Answer:each class would buy 35 rolls.
Step-by-step explanation:
Let x represent the number of rows of either floral sheeting or vinyl glasses that each class would buy.
The freshmen have already spent $307 on their float, plus they need to buy floral sheeting that costs $69 per roll. This means that the total cost of buying x floral sheetings would be
307 + 69x
The sophomores, who have spent $342 so far on theirs, still need to purchase vinyl grass at $68 per roll. This means that the total cost of buying x vinyl grass would be
342 + 68x
Since they are buying the same number of rolls to cover the same area, then
307 + 69x = 342 + 68x
69x - 68x = 342 - 307
x = 35
