Answer:
Step-by-step explanation: its the first answer cause i did this a bit ago
so i remember
3+4x<2(1+2x)
-2(x+6)< x-20
x-9 < 3 (x-3)
we will proceed to solve all cases to determine the solution of the problem
case A)
Eliminate the parenthesis of the left side
Group terms that contain the same variable, and move the constants to the opposite side of the inequality
Combine like terms
The solution is the interval--------> (-3,∞)
All real numbers greater than
therefore
The inequality A has solution
case B)
Eliminate the parenthesis of the right side
Group terms that contain the same variable, and move the constants to the opposite side of the inequality
Combine like terms
---------> is not true
therefore
The inequality B has no solution
case C)
Eliminate the parenthesis of the left side
Group terms that contain the same variable, and move the constants to the opposite side of the inequality
Combine like terms
Multiply by both sides
The solution is the interval--------> (8/3,∞)
All real numbers greater than
therefore
The inequality C has solution
case D)
Eliminate the parenthesis of the right side
Group terms that contain the same variable, and move the constants to the opposite side of the inequality
Combine like terms
Multiply by both sides
The solution is the interval--------> (0,∞)
All real numbers greater than
therefore
The inequality D has solution
therefore
the answer is
inequality has no solution. Option (b) is correct.

Josiah has two letters. The first weighs 2.9 ounces, and the second weighs 4.1 ounces. What is the total amount Josiah can expect to pay for postage?
$1.62
$1.64
$1.84
Answer:
$1.84
Step-by-step explanation:
We are given that a letter up to 1 ounce requires postage in the amount of $0.42, and each additional ounce (or fraction of an ounce) has an additional cost.
The function which represents the situation:
Now Joseph has two letters .
The weight of first letter = 2.9 ounces
Cost of first letter =
=
Now , second letter weighs 4.1 ounces
So, cost of second letter =
=
Thus the total amount Josiah can expect to pay for postage = $0.8+$1.04
=$1.84
Hence the total amount Josiah can expect to pay for postage is $1.84
