Answer:

a = 22

b = 31

c = 13

Step-by-step explanation:

The sum is the same in each row, column, and diagonal.

One of the diagonals is already complete.  The sum is:

16 + 25 + 34 = 75

So the first row adds up to 75:

a + 37 + 16 = 75

a = 22

The second row adds up to 75:

19 + 25 + b = 75

b = 31

And the third row adds up to 75:

34 + c + 28 = 75

c = 13

We can check our answer by finding the sum of each column and the other diagonal.

22 + 19 + 34 = 75

37 + 25 + 13 = 75

16 + 31 + 28 = 75

22 + 25 + 28 = 75

What is the answer to 7f/11 =7/11
serious [3.7K]
So,

\frac{7f}{11} =  \frac{7}{11}

Multiply both sides by 11.
7f = 7

Divide both sides by 7.
f = 1

Check.
\frac{7(1)}{11} =  \frac{7}{11}
\frac{7}{11} =  \frac{7}{11} This checks.
