Answer:

r=-3

Step-by-step explanation:

−18=9r+9

Step 2: Flip the equation.

9r+9=−18

Step 3: Subtract 9 from both sides.

9r+9−9=−18−9

9r=−27

Step 4: Divide both sides by 9.

9r /9  =-27/9

I will like to know how to solve this
Alexxandr [17]
This is a linear equation in x.

So you need to group like terms

1 + 4x =  - 5 + 7x
Let us group the x terms on the Right Hand Side of the equation and the constant terms on the Left Hand Side.

1 + 5 = 7x - 4x
We can now simplify

6 = 3x
Now let us divide both sides by 3.

\frac{6}{3}  =  \frac{3x}{3}

This implies that

2 = x
or

x = 2
Let us our answer

1 + 4(2) =  - 5  + 7(2)

1 + 8 =  - 5 + 14
9 = 9
Good we are right

Name the solid and find its volume. Use 3.14 as the approximate value of pi.
sineoko [7]

It is given in the question that the solid is a cone with height of 16 units and radius of 7 units .

The formula of volume of cone is

V = \frac{1}{3} \pi r^2 h

To find the volume, we substitute the given values of r and h and use 3.14 for pi. That is

V = \frac{1}{3} *3.14*7^2 *16 = 820.6 \ units \ cube

And that's the required volume of the cone .
