Step-by-step explanation:
Here you go mate
Step 1
6x+12=4x-18 Equation/Question
Step 2
6x+12=4x-18 Simplify
2x+12=-18
Step 3
2x+12=−18 Subtract 12
2x=-30
Step 4
2x=-30 Cross multiply by 2
answer
-15
A:
a + 2 x b + 3 x c = 19

Answer:
b=8
Step-by-step explanation:
7b = 56
divide each side by 7
7b/7 = 56/7
b = 8
The formula for the volume of a cone is V = PI x r^2 x h/3
r = 1/2 the diameter. 1/2 of 8 = 4 inches.
h = height = 12 inches.
Using 3.14 for PI, the formula now becomes:
V = 3.14 x 4^2 x 12/3
V = 3.14 x 16 x 4
V = 200.96 cubic inches.
You do not say if the answer needs to be rounded, so round the answer as needed.
Answer:
4x - 3y -18 = 0 or y = 4x/3 - 6
Step-by-step explanation:
We will have to find the slope of the line first
The formula for slope:
The standard form of equation of a line is:
y = mx + b
We know m,
So the equation will be:
We have to find the value of b, for that we will put any one of the point in the equation
So, putting (6,2)
2 = 4/3 * 6 + b
2 = 8 +b
b = -6
Putting the value of m and b in the standard form of equation of line,
..
