in 1960 there were approximately 3,000 million people on earth, in 1999 there were 6,000 people on earth what was the approximate rate of increase, in millions of people each year.

Answer:

x=5

Step-by-step explanation:

write x - 4 as a fraction with denominator = 1

5/x = (x - 4)/1

Now cross multiply

x(x - 4) = 5    multiply out and collect all terms on the left side of the equal sign

x2 - 4x - 5 = 0    factor the quadratic into two binomials

(x - 5)(x + 1) = 0   the product of two numbers = 0 when either number is zero

Therefore x = 5 or x = -1

The required simplified solution of the given expression is 11x -8.

Given that,
To determine the simplified expression that is equivalent to the 3(x-2)+2(4x-1).

What is simplification?

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
Given expression,
3(x-2)+2(4x-1)
Applying the distributive law in order to multiply the 3 and 4 in the respective parenthesis.
= 3x - 6 + 8x - 2
= 11x - 8

Thus, the required simplified solution of the given expression is 11x -8.
