After x weeks:
Jules will have: 1,200 + 40 x.
Kelsey will have: 400 + 50 x.
If we want to know in how many weeks will they have the same amount of money, we will make an equation:
400 + 50 x = 1,200 + 40 x
50 x - 40 x = 1,200 - 400
10 x = 800
x = 800 : 10
x = 80
Answer: In 80 weeks they will have the same amount of money.
The property shown is a B: substitution property, this is when you you the know that X=Y so X can be substituted in any equation with Y and Y can be substituted in any equation with X. hope this helps

is an irrational number ⇒ answer B
Step-by-step explanation:
Let us explain the meaning of:
- A rational number is a number that can be written as a fraction
- An irrational number is a number that cannot be expressed as a fraction
Examples:
Rational numbers : 10 , 
, 0.333
Irrational numbers : π , √8 , ∛25 , (2 + √5) , 
∵ 
∵ 3 is a rational number
∴ 
is a rational number
∵
∵ There is no square root of 8
∴ is an irrational number
∵ 0.3333 can be expressed as 
∴ 0.3333 is a rational number
∵ 
is a fraction
∵ All fractions are rational numbers
∴ is a rational number
is an irrational number
