Step1: Convert decimal to fraction
[tex]1.8( \frac{11x}{10} - 1.3) - 1.88 = - 24.02[/tex]
[tex]1.8( \frac{11x}{10} - \frac{13}{10} ) - 1.88 = - 24.02[/tex]
[tex]\frac{18}{10} ( \frac{11x}{10} - \frac{13}{10} ) - 1.88 = - 24.02[/tex]
Step2: Make denominator common

Multiply or divide the following expression: Reduce all answers to lowest terms. Factor the following completely.
Let f(x) = -x^2-4x+5
f(-3) = _______
f(3) + f(-3) = _______
A function assigns the values. The value of f(-3) and f(3) + f(-3) is 8 and -8, respectively.
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
Given the function f(x)=-x²-4x+5, therefore, the value of f(x) when the value of x is -3 is,
f(-3) = -(-3)² - 4(-3) + 5
f(-3) = -9 + 12 + 5
f(-3) = 8
Now, the value of f(x) when the value of x is 3 is,
f(3) = -(3)²-4(3)+5
f(3) = - 9 - 12 + 5
f(3) = -16
further, the value of f(3) + f(-3) is,
f(3) + f(-3) = -16 + 8
f(3) + f(-3) = -8
Hence, the value of f(-3) and f(3) + f(-3) is 8 and -8, respectively.

James is paid $18 an hour at his new job. He wishes to graph his total pay T, as a function of the number of hours, h. James works between 25 and 40 hours each week. Select from the drop-down menus to correctly complete each statement. To best show this information, the scale for the T-axis of his graph should go from 0 to at least Choose... , and the h-axis of his graph should go from 0 to at least Choose... .
Answer
T-axis of his graph should go from 0 to at least 720, and the h-axis of his graph should go from 0 to at least 40.
Explanation
We know form our problem that is the total pay, is the number of hours, and $18 is the rate per hour, so putting it all into an equation we get:
We also know that James works between 25 and 40 hours each week, so we can replace the number of hours in our equation to get how much he can make per week:
- For
- For
Now we know that he can make between $450 and $720 working between 25 and 40 hours per week. So, to best show this information the T-axis should go from 0 to at least 720; otherwise, we won't be able to show values between $450 and $720. Similarly, the h-axis should go form 0 to at least 40; otherwise, we wont be able to show values between 25 and 40 hours.

Jessica sold 15 times more books than Josh. Together they sold 256 books. How many did each one of them sell?
Jessica sells = 240 books,
Josh sells = 16 books.
Given:-The price of one book is = $15
Jessica sold 15 times more books than Josh.
In total, they have sold 256 books.
Solution:-We can easily find the answer using variables.
Let,
Josh sold a total of x books whereas Jessica sold a total number of 15x books.
together they sold 16x books.
So we can form the equation
16x= 256
by solving this equation we will get x=16
So, Josh sold 16 books and Jessica sold 16×15=240 books in total.

A triangular pyramid has a triangular base with height of 1.5 inches and base length of 4 inches, and height of 9 inches. What is the volume?
18 cubic inches
27 cubic inches
3 cubic inches
9 cubic inches
Answer:
V = 9 in^3
Step-by-step explanation
Comment
The formula for a Pyramid of any B is V = B * h / 3. You have to be able to calculate the Base or just be given in it.
In this case the Base is a triangle. So the first thing needed is the area of the base.
Base
Area_triangle = base length * height / 2
Neither the Base length nor the height need to be the same as the B and h used for the volume of the Pyramid
Givens
b = 4 inches
h = 1.5 inches
Area_triangle = 4 * 1.5 / 2
Area_triangle = 2 * 1.5
Area_triangle = 3 inches^2
Solution
Base (triangle) Area = 3
h = 9
V = B * h / 3
V = 3 * 9 / 3
V = 9 cubic inches
