Answer:
x=4
Step-by-step explanation:
-5(4-x)=-5x+20
We simplify the equation to the form, which is simple to understand
-5(4-x)=-5x+20
Reorder the terms in parentheses
+(-20+5x)=-5x+20
Remove unnecessary parentheses
-20+5x=-5x+20
We move all terms containing x to the left and all other terms to the right.
+5x+5x=+20+20
We simplify left and right side of the equation.
+10x=+40
We divide both sides of the equation by 10 to get x.
x=4

True or false</u></h2>
Since Leia and Thaddeus are reading the same 225-page book, and Leia starts reading the book and plans to read 25 pages a day while Thaddeus has already read 45 pages and is reading 20 pages a day, to determine if each statement is true or false the following calculations must be performed:
A) Leia will finish the book in 9 days.
Therefore, it is true that Leia will finish the book in 9 days.
B) f (x) = 20x represents the number of pages Thaddeus has read in x days.
- 20 x 5 = 200
- 45 + 20 x 5 = 245
Therefore, it is false that this equation represents the number of pages Thaddeus has read in x days.
C) They will both finish the book in 9 days.
- 45 + 20 x 9 = X
- 45 + 180 = X
- 225 = X
Therefore, it is true that they will both finish the book in 9 days.
