You'd multiply 8 by 4 to get 32, and then add 2 to get 34, which is the mans age. I hope this helps!

Answer:  The man is 34 years old.

Step-by-step explanation:  Given that a man's age is two years more than four times his son's age and his son is 8 years old now.

We are to find the age of the man.

Let x and y represents the age of the man and his son respectively.

Then, according to the given information, we have

x=4\times y+2\\\\\Rightarrow x=4y+2~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)

and

y=8~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(ii)

Substituting the value of y from equation (ii) in equation (i),we get

x\\\\=4y+2\\\\=4\times8+2\\\\=32+2\\\\=34.

Thus, the man is 34 years old.

Consider the following switch statement where x is an int. If x is currently equal to 5, what will the value of x be after the s
Sphinxa [80]

Answer:

x=11

Step-by-step explanation:

The switch case works like an if or if-else, where each of the cases are conditionals. Here we have 7 cases and we know that our variable begins with x=5.

First, it enters to case 5 because of x=5, so x+=3, this means we add 3 to the actual value of the variable ⇒ x=8.  

At this point, if there's not break the program continues to the next case, executing the statements until a break or the end on the switch is reached.  

In this order, the x = 8 and next we add 1 (case 6) ⇒ x=9. We add 2 (case 7) x+=2 ⇒ x=10. Then we rest 1 (case 8) ⇒ x=9 and then we add 1 again as in case 9 ⇒ x=11.

Please answer from the question above :)
AlekseyPX

Answer:

205/6

Step-by-step explanation:

The question simply asks us to plug in 45 minutes into the given equation. In the graph, we see that y-axis is defined to be time. Therefore we set y=45 and solve for x.

45=-6/5x+86

-41=-6/5x (subtract 86 from both sides)

-41*(-5)=-6/5x*(-5) (multiply both sides by -5)

205=6x (divide both sides by 6)

205/6=x
