The Equation of life expectancy is x- 0.4(2) = 80.2.
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
The life expectancy of a woman born in 1995 was 80.2 years.
The life expectancy increased 0.4 year every 5 years.
So, from 1995 to 2005 there are two times the life expectancy increase.
let the lifeexpectancy by x.
Thus, the equation is
x- 0.4(2) = 80.2

Answer:
a. L - 0.4(2)= 80.2 or L - 80.2 = 0.4(2) or 80.2 + 0.4(2) = L
b. No; The equations must be equivalent. They may look different, but all equations can be rewritten as L= 80.2 + 0.4(2).

Step-by-step explanation:
We are given the expression C>D>0.
As C and D represent two different school populations. This means that C and D will be natural numbers.
C+D<2×(C+D)

Answer:
28 years
Step-by-step explanation:
youngest brother's age = x
middle brother's age = x+2
oldest brother's age = x+4
3(x-2) = (x+2)+48
[simplify]
3x-6 = x+50
[add 6 to each side]
3x = x+56
[subtract x from each side]
2x = 56
[divide each side by 2]
x = 28
By forming an equation based on the information given in the question, we can deduce that the age of the youngest brother is 26 years.
Let's assume the youngest brother's age as 'x'. Since it's given that three brothers have **consecutive even integer** ages, the other two brothers' ages will be 'x+2' and 'x+4' respectively.
Per the question, three times the age of the youngest brother exceeds the oldest brother's age by 48 years, so we'll build an equation accordingly, which is 3x = x+4+48.
Now, let's simplify this equation: 3x = x+52. Subsequently, when we subtract x from both sides, we get 2x=52. Breaking it down further, we are left with x=26.
So, the age of the youngest brother is 26 years.
