Answer:

Step-by-step explanation:

y+ 20= x+ 15( Vertically opposite angles)

y+ 20- 15= x

x= y+ 5 __(1)

3x+ 5=4y- 15

Substituting (1)

3(y+5)+ 5= 4y-15

3y+15+5=4y- 15

y=15+20

y= 35

x= 40

Answer:

$\frac{59}{8} or 7\frac{3}{8}$

Step-by-step explanation:

$\frac{80}{4} - 12\frac{5}{8}$

First you need to make the 12 5/8 into an improper fraction by multiplying 12 by 8 and then adding the total by 5.

$12\frac{5}{8}$ -> $\frac{101}{8}$

Now you have $\frac{80}{4} - \frac{101}{8}$ so you need a common denominator by multiplying the first fraction by 2

$\frac{80}{4} -> \frac{160}{8}$

Then you subtract 160 - 101 which equals 59.

$\frac{59}{8} or 7\frac{3}{8}$
