With the equation:
0.15 x = 30
x = 30 : 0.15 = $200
A regular price of TV is $200.
Which could not be used to determine x ( we shall plug in the value 200 ):
A ) 0.15 * 200 = 200 - 30
30 ≠ 170
B ) 0.85 * 200 = 200 - 30
170 = 170 ( correct )
C ) 200 - 0.15 * 200 = 200 - 30
200 - 30 = 200 - 30
170 = 170 ( correct )
D ) 0.15 * 200 = 30
30 = 30 ( correct )
Answer:
A ) 0.15 x = x - 30
15:24
divide both sides by 3
b. 5:8
for 6:30
divide both sides by 6
1:5
If we imagine it in our head, we can see that the width (base) is 2 and the height is 9
the area is 1/2bh or 1/2*2=9 square units
it is rotated around x axis
meaning we have a sideways cone that is 2 hight and radius is 9
Vcone=1/3(hpir^2)
h=2
r=9
V=(1/3)(2)(3.141592)(9^2)
V=(2/3)(3.141592)(81)
V=(54)(3.141592)
V=169.6459
round
V=169.6 cubic units
base is 2 units
height is 9 units
area is 9 square units
it's a cone (sideways)
it has a volume of 169.6 cubic units

Answer:
The correct choice is marked
Step-by-step explanation:
When you end with a true statement, it means any variable value will make the equation true. There are infinite solutions.
When you end with a false statement, it means no value of the variable will make the equation true. There are no solutions.

Answer:
C
Step-by-step explanation:
y=mx+b
m(slope)=rise/run=1
b(y intercept)=2
y=x+2
