The value of y in the code segment is 444
<h3>How to determine the value of y?</h3>
The code segment is given as:
y = int(3 * '4')
Evaluate the expression in the bracket
y =int('444')
Remove the bracket
y = 444
Hence, the value of y in the code segment is 444

Answer:
a) 4
b) 2
Step-by-step explanation:
a) multiply the coefficients and add the exponents
(4)(1) ·  = 4
 = 4
b) divide the coefficients and subtract the exponents
(14 ÷ 7) ·  = 2
 = 2
 
        
             
        
        
        
Answer:
52
Step-by-step explanation:
We can write this out as an equation. Let's say that the teacher's age is x. Triple the teachers age plus the students age is 163, which can be written out as:

We want to isolate the variable, so subtract 7 from both sides. This gives us:

Finally, we divide both sides by  3, giving:

So the teacher is 52 years old. 
Hope this helps!
