2 sides equations 1. 15x-8x= 5x +48

2. 4-2y= 4y

3. 4-5x= 3+x

4. 2x+8=2x-5

5. 4y+9= 4y+9

15x-8x-5x=48

3x=48

or X=16

4=4y+2y

or 4= 6y

or 4/6=y

or y=2/3

4-5x= 3x

or 4=5x+3x

or 4=8x

or 4/8=X

or X=2

2x=2x-5+8

or,2x= 2x-13

or 2x+2x=13

or 4x=13

or X= 13/4

or X =3.25

4y=4y+9-9

or 4y=4y+0

or 4y-4y=0

or 0=0

a28=58

step-by-step explanation:

a1=a1+(n-1)d

a28= 4+ (28-1)2

a28=4+(27)(2)

a28=4+54

a28=58

other answer is correct. i had used the radius of the radius somehow. a website:
