<span>So
the given numbers are:
=> One year, the price of wheat is 8.87 dollars
=> the next year, the price of wheat is 9.60 dollars.
We were asked to round each prices of bushels of wheat to its nearest tenths.
=> 8.87, where 8 before the decimal point is ones, 8 next to decimal point
is tenths and 7 is the hundredths.
=>round off to the nearest tenths
=> 8.9
=> next is 9.60, where 9 is the ones value, 6 is the tenths value and 0 is
the hundredths.
=> round off to nearest tenths
=> 9.6

Looking at the question, I'm assuming it has a mistake.
However, I will first attempt to solve it normally:
Simply combine like terms to get 5x = 180, and thus x = 36, and y = 72
The first mistake possibility is that the first equation should be <u>3x + 2y = 180</u>
If that is the case, simply substitute in 2x for y, turning the equation into
3x + 2 (2x) = 180
3x + 4x = 180
7x = 180
Thus, x = 25.715 and y = 51.43
Another possible mistake is that the first equation should be <u>3y + 2x</u><u> </u><u>= 180</u>
Solve similar to the first mistake
3 (2x) + 2x = 180
6x + 2x = 180
8x = 180
Thus, x = 22.5, and y = 45
Hope it helps :)

Answer:
The average rate of change is -3.
Step-by-step explanation:
Given : Function 
over the interval 2 ≤ x ≤ 4.
To find : What is the average rate of change ?
Solution :
Function over [2,4]
The rate of change is the slope of the line,
So, 
Substitute,
Therefore, The average rate of change is -3.
