The age of triplets is 42 years old
Step-by-step explanation:
The question in English is
The sum of the ages of twins and triplets is 150 years if the ages are exchanged the new sum is 120 years. What is the age of triplets?
Let
x -----> twins age
y ----> triplets age
we know that
2x+3y=150 ------> equation A
2y+3x=120 -----> equation B
Solve the system by graphing
The intersection point both graphs is the solution of the system
The solution is the point (12,42)
see the attached figure
therefore

The radius of can is 2.524 inches
<em><u>Solution:</u></em>
Given that large can of tuna fish that has a volume of 66 cubic inches and a height of 3.3 inches
To find: Radius
Given a large can of tuna fish, we know that can is generally of cylinder shape, we can use the volume of cylinder formula,
<em><u>The volume of cylinder is given as:</u></em>
Where,
"r" is the radius of cylinder
"h" is the height of cylinder
is a constant equal to 3.14
Substituting the given values in above formula,
Thus the radius of can is 2.524 inches
