Step-by-step explanation:
-2(-7)-9
14-9=5
Answer:
Step-by-step explanation:
x + y = 10
22x + 14y = 172
-22x - 22y = -220
22x + 14y = 172
-8y = - 48
y = 6 ceramic vases
x + 6 = 10
x = 4 glass vases
Average speed is 12.6 miles per hour
<em><u>Solution:</u></em>
Given that team tool bella canoed
miles in
hours
To find: average rate of speed in miles per hour
From given information,
![distance = 15\frac{3}{4} \text{ miles } = \frac{15 \times 4+3}{4} = \frac{63}{4} \text{ miles}](https://tex.z-dn.net/?f=distance%20%3D%2015%5Cfrac%7B3%7D%7B4%7D%20%5Ctext%7B%20miles%20%7D%20%3D%20%5Cfrac%7B15%20%5Ctimes%204%2B3%7D%7B4%7D%20%3D%20%5Cfrac%7B63%7D%7B4%7D%20%5Ctext%7B%20miles%7D)
![time = \frac{5}{4} \text{ hours}](https://tex.z-dn.net/?f=time%20%3D%20%5Cfrac%7B5%7D%7B4%7D%20%5Ctext%7B%20hours%7D)
To find the speed we use the below formula,
![speed = \frac{distance}{time}](https://tex.z-dn.net/?f=speed%20%3D%20%5Cfrac%7Bdistance%7D%7Btime%7D)
Substituting the given values we get,
![speed = \frac{\frac{63}{4}}{\frac{5}{4}}\\\\speed = \frac{63}{4} \times \frac{4}{5} = \frac{63}{5} = 12.6](https://tex.z-dn.net/?f=speed%20%3D%20%5Cfrac%7B%5Cfrac%7B63%7D%7B4%7D%7D%7B%5Cfrac%7B5%7D%7B4%7D%7D%5C%5C%5C%5Cspeed%20%3D%20%5Cfrac%7B63%7D%7B4%7D%20%5Ctimes%20%5Cfrac%7B4%7D%7B5%7D%20%3D%20%5Cfrac%7B63%7D%7B5%7D%20%3D%2012.6)
Thus average speed is 12.6 miles per hour
