PLEASE HELP!! Identify which equations have one solution infinite many solutions or no solution!
1/2y+3.2y=20
15/2+2z-1/4=4z+29/4-2z
3z+2.5=3.2+3z
1.1+3/4x+2=3.1+3/4x
4.5r=3.2+3.2+4.5r
2x+4=3x+1/2

PLEASEEE AND THANK YOUUU!

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

hello from mrbilldoesmath!

answer:   x^2 + y^2 = 1024

discussion:

the equation of a circle with center (h,k) and radius "r" is

(x-h)^2 + (y-k)^2 = r^2.

in our case

(x-0)^2 + (y-0) ^2 = 32^2 = 1024

you,

mrb

can i know which language is this?
