Look at pseudocode segment below. y ← x + x + x + x + x / / line a z ← y + y + y / / line b If x = 6 before this segment is executed, what is the value of z after execution?

90.

Step-by-step explanation:

We have two lines of code:

y ← x + x + x + x + x

z ← y + y + y

and, x=6 before the execution. Then, when the program starts to run we obtain:

y ← 6 + 6 + 6 + 6 + 6

y ← 30

z ← 30+30+30

z ← 90.

Then, the value of z after excecution is 90.
