Answer:
x^a-b
Step-by-step explanation:
x^a/x^b=
x^a-b this only works if a and b have the same base
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:
answered
Step-by-step explanation:
A) there y- coordinates are same . This means that the points lie on the x- axis only.
b) since the y- coordinate is zero of both the points. The distance between them must be same as the distance between their x- coordinates. Which can be easily obtained with help of the number line. Here the distance will be equal to 9 units.
c) since the y- coordinate is zero of both the points. The distance between them must be same as the distance between their x- coordinates. Which can be easily obtained with help of the number line. Here the distance will be equal to 9 units

45 1/4-> 45.25 * .5 = 22.625 = 22 5/8
gusset plate :
5 3/4 -> 5.75 * .5 = 2.875 = 2 7/8
3 1/2 -> 3.5 * .5 = 1.75 = 1 3/4
47 1/4 -> 47.25 * .5 = 23.625 = 23 5/8
2 * .5 = 1
