Let the two numbers be represented by x and y.
.. y = 29 +3x
.. 5(y -x) = 345
From the second equation,
.. y -x = 345/5 = 69
Substituting for y in the first, we have
.. 69 +x = 29 +3x
.. 40 = 2x
.. x = 20
Then
.. y = 29 +3*20 = 89
The two numbers are 89 and 20.
A. 12
You use the formula A2+B2=C2
6^2+10^2 = X^2
36+100=x^2
136=x^2
Square root both sides
X= 11.6 round up to 12
