Answer:
24 years old
Step-by-step explanation:
Let Malvin's age be x.
- x / 2
- x / 2 + 5 = 5x / 10 [ By taking the L.C.M.]
- ( 5x / 10 ) * ( 1 / 3 ) = 5x / 30 [ Multiply with the reciprocal of 3 ]
- ( 5x / 30 ) * 2 = 5x / 15
Now let's solve the equation,
5x / 15 = 8
5x = 8 * 15
5x = 120
x = 120 / 5
x = 24
Therefore, Malvin is 24 years old.

to both sides.


Dividing both sides by 10.


∴ 
In the graph it is the point with x- coordinate 1 and y-coordinate - 2
Answer: f ( 1 ) = - 2
Answer:
Step-by-step explanation:
f(x)=x+1
then,
f(-5)=(-5)+1
=-4
By minusing 12 to both sides
d+12=2
-12=-12
d =-10
