Answer:
X= 7
Step-by-step explanation:
Since x= 2 you would plug it in 3.5 times 2 = 7
Answer:

Step-by-step explanation:
we know that
The volume of a right circular cone is equal to

where
r is the radius of the base of the cone
h is the height
Solve for r-----> That means, isolate the variable r
so
step 1
Multiply by 3 both sides

step 2
Divide by
both sides

step 3
take square root boot sides

You would select the points with the x-values -3 and 2 and use the slope formula:
(-3, -36) and (2,4)

← slope formula
x1 = -3 y1 = -36 and x2 = 2 y2 = 4
Step-by-step explanation:
Okay! To do this you need to have x on one side (isolate the variable) and also combine like terms. Like terms are terms with the same exponent and variable, like 8x and 6x.
8x+1=-6x-2 To combine like terms here we have to move -6x to the other side of the equation by adding it (using inverse operations). 8x+6x=14x
14x+1=-2 now subtract 1 from both sides.
14x=-3
Divide both sides by 14 and x=-3/14

Answer: There are 4 tubes of paint she purchased.
Step-by-step explanation:
Since we have given that
Amount spend on tubes of paint and brushes for an art project = $16
Cost of each tube of paint = $3
Cost of each brush = $0.50
Let the price of tube of paint be 'x'.
Let the price of brush be '2x'.
So, According to question, it becomes,

Hence, there are 4 tubes of paint she purchased.
