The equation 7.50(n+0.2)=189 can be used to model the number of books, n , maggie orders. How many books does maggie order?
Reptile [31]
N= number of books

7.50(n + 0.2)=189
multiply 7.50 by each term in parentheses

(7.50*n) + (7.50*0.2)= 189
7.50n + 1.5= 189
subtract both sides by 1.5
7.50n= 187.50
divide both sides by 7.50
n= 25

ANSWER: She ordered 25 books.

Hope this helps! :)

Which is the value of this expression when X=-2
e-lub [12.9K]
A) x^2 +x -30 = 0 is factored by looking for two factors of 30 that differ by 1. We know ...  30 = 1*30 = 2*15 = 3*10 = 5*6The last two factors differ by 1, so we can factor the trinomial as  (x +6)(x -5) = 0
b) The solutions are found by finding values of x that make these factors zero. The only way the product will be zero is if one or more of the factors is zero.  x + 6 = 0  x = -6 . . . . . subtract 6
  x - 5 = 0  x = 5 . . . . . add 5
The solutions are x = -6 or x = 5These are the values of x that will satisfy the equation (make it true). What they mean depends on the meaning of the variable and the situation the equation is a model of.
