Answer:
D) 9
Step-by-step explanation:
8 + 9 + 10 + 7 =39
48 - 39 = 9
The percent increase in the iron was 50%. 1.2/2 = .6 1.2 + .6 = 1.8
You can simply put the equation as 9x = 36 and divide by 9, then x = 4
Answer:
d=10u
Q(5/3,5/3,-19/3)
Step-by-step explanation:
The shortest distance between the plane and Po is also the distance between Po and Q. To find that distance and the point Q you need the perpendicular line x to the plane that intersects Po, this line will have the direction of the normal of the plane
, then r will have the next parametric equations:

To find Q, the intersection between r and the plane T, substitute the parametric equations of r in T

Substitute the value of
in the parametric equations:

Those values are the coordinates of Q
Q(5/3,5/3,-19/3)
The distance from Po to the plane

X + 0.5 + 3x - 2 = 3x + 1.5
X= 3.5
Putting the all x on the right side and distributing all the numbers on the left side
