Answer:

19.2 kg

Step-by-step explanation:

Amount of Bananas consumed in US per year = 5.77 million metric tons

Since 1 million = 10^{6} and 1 metric ton = 1000 kg, we can write:

Amount of Bananas consumed in US per year = 5.77 \times 10^{6} metric tons

Amount of Bananas consumed in US per year = 5.77 \times 10^{6} \times 1000 = 5.77 \times 10^{9} kg

Number of people in US = 301 million = 301 \times 10^{6}= 3.01 \times 10^{8}

We have to find how many kilograms of bananas are consumed per person in 1 year in US. For this we have to divide the total amount of bananas eaten in US per year with total number of people in US, which will be:

\frac{5.77 \times 10^{9}}{3.01 \times 10^{8}} \\\\ = 19.2

This means, 19.2 kilograms of bananas are eaten in US per person in a year.

Solve the system of equations -x+ 2y = –11 and 5x – 8y = 39 by<br> combining the equations.
Alchen [17]

Answer:

x=-5, y=-8. (-5, -8).

Step-by-step explanation:

-x+2y=-11

5x-8y=39

---------------

5(-x+2y)=5(-11)

5x-8y=39

---------------------

-5x+10y=-55

5x-8y=39

--------------------

2y=-16

y=-16/2

y=-8

-x+2(-8)=-11

-x-16=-11

-x=-11+16

-x=5

x=-5
