Answer:

Step-by-step explanation:
The total number of students who studied only two subjects is 13.
The given parameters:
- <em>Total number of students, n = 55 </em>
- <em>Number of physics students = 21</em>
- <em>Number of geography students = 24</em>
- <em>Number of economics students = 23</em>
- <em>Number of students for the 3 subjects, = x</em>
- <em>Number of students who studied non = 2x</em>
The number of students who studied only two subjects can be determined by applying overlapping three sets formula as shown below;

Thus, the total number of students who studied only two subjects is 13.

Answer:
option B. G
Step-by-step explanation:
Let
y ---->ounces of orange juice
x ---> ounces of pineapple juice
we know that
The ratio of orange juice to pineapple juice is equal to

substitute the given values

simplify

<u><em>Verify each graph</em></u>
Remember that the formula of slope is "rise over run", where the "rise" (means change in y, up or down) and the "run" (means change in x, left or right)
we have

that means
5 ounces of orange juice per 3 ounces of pineapple juice
Graph F
The slope is

Graph G
The slope is

Graph H
The slope is

Graph J
The slope is

The value of 2 is the value closest to 1.67
therefore
The graph that has a slope that best represents the ratio of orange juice to pineapple juice is Graph G
X<=50.
< is less than
> is greater than
Without him paying the extra fee is <=50
x is pounds.
Now, you have x<=50.
Hope this helped☺☺
So sum the prime factors up
25=5*5, 5+5=10
26=2*13, 2+13=15
27=3*3*3, 3+3+3=9
15>10>9
26 is biggest
pick 26
