Answer:
Step-by-step explanation:
Let the boy's present age be x.
Let his dad's present name be y.
Last year, his dad was 8 times as old as him. Subtract one year from each their ages and multiply the son's age by 8:
(y - 1) = 8(x - 1) ______ (1)
Now, his dad's age is the square of his age:
y = _________(2)
From (1):
y = 8x - 8 + 1
y = 8x -7
Put this in (2):
This problem has been represented in the form of a quadratic equation.
If 9 is 1/3 of the problem, then 9 x 3
= 27 would be the answer
The answer is 5
ratio 4:10 simplified : 2:5

Step-by-step explanation:
<u>Evaluate Expressions</u>
An algebraic expression consists of a set of variables and constants related by algebraic operations like addition, subtraction, multiplication, etc.
To evaluate an algebraic expression, we replace the variables for the constant value they are assigned.
Let's consider the expression:
for x=10, y=-1, z=0
Substituting the variables for their values:
The value of the expression is 11
