For this case we have the following equation:

6x + 5 = 5x + 8 + 2x

We must find the solution.

We add similar terms from the right side of the equation:

6x + 5 = 7x + 8

We subtract 5 from both sides of the equation:

6x = 7x + 8-5\\6x = 7x + 3

We subtract 7x on both sides of the equation:

6x-7x = 3

Different signs are subtracted and the sign of the major is placed:

-x = 3

We multiply by -1 on both sides of the equation:x = -3

Thus, the solution of the equation is x = -3. -5 is not a solution to the equation.

Answer:

x = -3. -5 is not a solution to the equation

balandron [24]

The formula for the volume of pyramid is,

V=\frac{Bh}{3}

Here, B is base area and height of pyramid.

The volume expression for group 4 is,

V=\frac{1}{3}\cdot(\frac{8\cdot4}{2})\cdot9

Here, expression,

\frac{8\cdot4}{2}

represents the base area and 9 represent the height of pyramid.

So height of the pyramid created by group 4 is 9.

4 2/3 divide by 1 2/3
sladkih [1.3K]

Answer:

14/5

Step-by-step explanation:

I'd suggest rewriting both mixed numbers as improper fractions.  Then we'd have:

14/3 and 5/3

Dividing 14/3 by 5/3 is equivalent to dividing 14 by 5, since the denominators are the same (3).

Quotient is 14/5.
