$25×6.50=152.5
50÷13=0.26
Hey. Good afternoon.
120$ --- 80%
x --- 100%
80x = 12000
x = 12000/80
x = 150$
Sorry my bad english, i'm Brazilian.
Answer:
x=7
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
The points where the 2 graphs intersect is where x = 0 and x = 2.
- 2 2
x = INT x dA / INT dA
0 0
INT dA = INT -x^2 + 4x + 3 - (x^2 + 3 ) dx = INT -2x^2 + 4x
= -2 x^3/3 + 2x^2
= 2.667 between 0 and 2
xdA = -2x^3 + 4x^2 INT xdA = -x^4/2 + 4x^3/3 = 2.667
centroid = 2.667 / 2.667 = 1 (x = 1)
