It will be 3, you just subtract 11 to 8 you’ll get BC
I/13 x (where x is the age)
Step-by-step explanation:
Let the age in consideration is 'x' in variable
It is mentioned in the question as 1/13 the age
so, 1/13th the age be 1/13*x
hence the algebraic expression to be written as x/13 or 1/13*x
Here 1/13 is multiplied with x, the age in variable.
7x-9 < 12 add 9 to both sides
7x < 21 divide both sides by 7
X < 3 X is less than 3
1/4x+8 > 11 subtract both sides by 8
1/4x > 3 multiply both sides by 4
X > 12 X is greater than 12
X <3 or X > 12
Answer:
2 irrational solutions
Step-by-step explanation:
using the quadratic formula:
3x²−x−5=0
where a = 3, b = -1 and c = -5, plug in those values in the quadratic formula
you get two solutions:
both can be written as:
They are irrational as they cannot be written in the form p/q where p and q are whole numbers (integers)
Answer:
Step-by-step explanation:
An equation is 5p + 2 = 18.5.
The 1950 population was approximately 3.3 million.
Step-by-step explanation:
If p million was the population in 1950 the equation is:
5p + 2 = 18.5
5p = 16.5
p = 16.5 / 5
p = 3.3 million.
