Answer:

Step-by-step explanation:

x + 2y = 14

x + y = 8.....x = 8 - y

8 - y + 2y = 14

y + 8 = 14

y = 14 - 8

y = 6

x + y = 8

x + 6 = 8

x = 8 - 6

x = 2

solution : x = 2 and y = 6.....or (2,6)

Uncle Drew scored 28 points in 5 5/6 end fraction minutes during a game of basketball. How many points did he average per minute
8090 [49]

Answer:

Ok so I think the answer is 4.8 points per minute

Step-by-step explanation:

Why because Uncle Drew scored 28 points in 5 \frac{5}{6} minutes. We have to convert the mixed fraction first:

t = 5 \frac{5}{6}=\frac{5\cdot 6+5}{6}=\frac{35}{6}

So, the time is 35/6 minutes.

In order to find the number of points he scored in a minute, we have to divide the total number of points by the number of minutes, so:

mean = \frac{28}{35/6}=28 \cdot \frac{6}{35}=4.8

So, he scored 4.8 points per minute.

I hope you foundthis helpful.
