Answer:

option 1

Step-by-step explanation:

Combine like terms

1 + 4.25n + \frac{3}{2}p - 3 + (-2p) + \frac{5}{4}n=1 - 3 + 4.25n +\frac{5}{4}n+\frac{3}{2}p+(-2p)\\

                                                   = -2 +  4.25n + 1.25n + \frac{3}{2}p-\frac{2*2}{1*2}p\\\\= - 2 + 5.5n +\frac{3}{2}p+\frac{4}{2}p\\\\= -2 + 5.5n +\frac{3-4}{2}p\\\\= - 2 + 5.5n -\frac{1}{2}p\\\\= 5.5n - \frac{1}{2}p - 2

Please help and include explanation !!
Sidana [21]

The vertical angles are equal to each other, that is, one of the one-sided corners will be 116°.

The sum of the one-sided angles is 180°, which means: 4x+116 = 180°

4x = 180-116 => 4x = 64°

x = 64/4 = 16°.

The sum of two adjacent angles is 180°. which means, that: 2x-3y = 180-64 = 116°

2x-3y = 116°

-2x+3y = -116

-32+3y = -116

3y = -116-(-32)

3y = -84

y = -84/3 => y = -28.
