Answer:

Step-by-step explanation:

15 - 2(7 - x) = 7

collect like terms

-2(7 - x) = 7 - 15

-2(7 - x) = -8

divide both sides by -2

7 - x = -8/-2

7 - x = 4

collect like terns

-x = 4 - 7

-x = -3

dividing both sides by -

x = 3

devlian [24]

Answer:

12 1/4

Step-by-step explanation:

(7 + X) × 8 - 4 × X = 56

7 + X × 8 - 4 × X = 56

7 + 8X - 4 × X = 56

7 + 8X - 4X = 56

7 + 4X = 56

4X = 56 - 7

X = 49/4

X = 12 1/4

The formula below gives the sum of the degrees, S, of the interior angles of a polygon. If n represents the number of sides, whi

Helga [31]

Answer:

The equation representing the value of n is, $n=\frac{S}{180^{\text{o}}}+2$ .

Step-by-step explanation:

The formula to compute the sum of the degrees, S, of the interior angles of a polygon is:

$S=(n-2)\times 180^{\text{o}}$

Compute the equation of n as follows:

$S=(n-2)\times 180^{\text{o}}$

$\frac{S}{180^{\text{o}}}=(n-2)$

$n=\frac{S}{180^{\text{o}}}+2$

Thus, the equation representing the value of n is, $n=\frac{S}{180^{\text{o}}}+2$ .
