9514 1404 393

Answer:

  34

Step-by-step explanation:

Let x represent the number of nickels Abby has. Then the number of dimes is 61-x. The total value of the coins, in cents, is ...

  5x +10(61-x) = 440

  -5x +610 = 440 . . . . . simplify

  x - 122 = -88 . . . . . . . .divide by -5

  x = 34 . . . . . . . . . . . . add 122

Abby has 34 nickels in her collection of coins.

Answer:

x = 1

Step-by-step explanation:

Given equation:

\frac{x}{2}+\frac{1}{3}=\frac{5}{6}

Now,

subtracting  \frac{1}{3} from both sides

we get

⇒ \frac{x}{2}+\frac{1}{3}-\frac{1}{3}=\frac{5}{6}-\frac{1}{3}

or

⇒ \frac{x}{2}+0=\frac{5}{6}-\frac{1}{3}

or

⇒  \frac{x}{2}=\frac{5\times3-6}{6\times3}

or

⇒ \frac{x}{2}=\frac{9}{18}

or

\frac{x}{2}=\frac{1}{2}

Now, multiplying both sides with the number 2, we get

x = 1

The sum of all interior angles in a polygon is
180(n - 2), where n = the number of sides in the polygon.

now, notice this figure above, it has 5 sides, namely is a PENTAgon, so the sum of all its interior angles is 180( 5 - 2), or 540, therefore

\bf (4x)~+~(3x+15)~~+~~(4x-25)~~+~~(3x+25)~~+~~(2x-3)=540
\\\\\\
16x+12=540\implies 16x=528\implies x=\cfrac{528}{16}\implies x=33
