Simplify it and compare

(7-2-1) z = 8 - 2

4z = 6

so the 3rd

Answer : The simplified form of the equation is, 4z = 6

Step-by-step explanation:

As we are given the expression of equation. Now we have to simplified this expression.

The given expression is:

7z + 2 = 8 + 2z + 1z

Taking like terms together.

7z - 2z - 1z = 8 - 2

By solving the expression, we get:

4z = 6

Hence, the simplified form of the equation is, 4z = 6

1. Use the figure below to answer the questions.<br><br> (a) Solve for x.

Dmitry [639]

Let's see what to do buddy...

_________________________________

The sum of the angles of each n-sided figure is found in the following equation :

$(n - 2) \times 180$

The question's figure is 5-sindes figure

so the sum the angles equal :

$(5 - 2) \times 180 = 3 \times 180 = 540 \\$

So we have :

$90 + 107 + 144 + 138 + x = 54 0 \\$

$479 + x = 540$

Subtract the sides of the equation minus 479

$x = 540 - 479$

$x = 61$

And we're done.

Thanks for watching buddy good luck.
