Answer:
We cannot find a solution to the system of equations.
a+b = 5.30
2a + 2b = 14
Step-by-step explanation:
Let a = the price of an apple
let b = price of an orange
a+b = 5.30
2a + 2b = 14
Multiply the first equation by 2
2a+ 2b = 10.60
Subtract the second equation
2a+2b = 10.60
-2a+2b = 14
---------------------------
0 = -3.40
This is never true so there is no solution
Answer:

Step-by-step explanation:
The mean is the sum of the weights divided by the number of weighings.

To find the length of segment AC, we must find the total rise and total run between the two points.
Point C is located at (-5, 5). Point A is located at (3,-1). To find the rise, subtract the y-value of A from the y-value of C:

The rise of this segment is 6.
To find the run, subtract the x-value of A from the x-value of C:

The run of this segment is 8.
We can use the Pythagorean Theorem to find the length of this segment. The theorem uses the following formula:

The segment represents the hypotenuse, and the rise and run represent the legs of this segment. We know that the two legs' lengths are 6 and 8, so plug them into the equation:



Square root both sides to get c by itself:


The length of segment AC is
10.
1 in. = 25 ft.
12.5 in. = ___ft
25/1=25
12.5*25=312.5
So the answer to your question is 312.5 feet.
Hope this helps! :)
