Answer:
$6.75
Step-by-step explanation:
1: In this explanation, let's let one watermelon be w, and one orange be o.
2: From the passage, 1w + 5o = $11.
3: Also from the passage, 3w + 5o = $24.50
4: We can then use a simultaneous equation to work them out - both equations we have use 5 oranges.
3w + 5o = 24.5 (equation 1)
1w + 5o = 11 (equation 2)
5: We can now take the second equation away from the first :
3w - 1w = 2w, 5o - 5o = 0, 24.5 - 11 = 13.5
Now we know 2w = 13.5
6: If 2w = $13.50, one watermelon will be half of that, so $6.75
Hope this helps, let me know if you have any further questions :)
Answer: The graph is shown below
The solution to the system is (x,y) = (2,3)
=============================================================
Explanation:
To graph 
, we need two points. Generating any (x,y) point involves picking a random x value to find its paired y value. For instance, if you plugged in x = 0, you should get to y = -2 which is the y intercept. Then trying something like x = 2 will lead to y = 3. This line goes through (0,-2) and (2,3). This line is shown in red below.
The blue line is horizontal and goes through 3 on the y axis. Every point on this horizontal line has the same y coordinate of 3. The x value doesn't matter, so it's not part of the equation y = 3.
The intersection of the red and blue line is the solution to the system. That intersection occurs at (x,y) = (2,3). This means x = 2 and y = 3 pair up together to make both original equations true.
Since this system has at least one solution, we consider it a consistent system.
Answer:
Step-by-step explanation:
h^2=x^2+y^2, since this is a square x=y=s so
220^2=2s^2
2s^2=48400
s^2=24200
s=24200^(1/2)m (exact)
s=155.56m (rounded to nearest hundredth of a meter)
One hectare is equal to 10000m^2
A=24200m^2(h/10000m^2)
A=2.42 hectares
