Asap algebra 6th grade 50 pts. answer all if you don't i will have an admin delete your answer

Hey there!!

We solve all these by the process of Substitution.

(1) 45x=180 ; x=4

... (45)(4) = 180

... 180 = 180

(YES)

(2) 420/d=30 ; d=15

... 420/15=30

... 28≠30

...420/30 = d

... d=14

(NO, d=14)

(3) 37+s=80/2 ; s=13

... 37+s=40

... 37+13=40

... 50≠40

... 37+s=40

... s=3

(NO,s=3)

(4) 52+g=45+11 ; g=3

... 52+g=56

... 52+3=56

... 55≠56

52+g=56

... g=4

(NO,g=4)

(5) 13+14=3f ; f=9

... 27 = 3f

... 27=3(9)

... 27=27

(YES)

Hope it helps!

i would be happy to . most people on would also love to i'm sure. if you just want someone who has done algebra before and want a little more personal relationship than just begging strangers for , i can certainly be of service. i do have college myself so i might not be 24/7.
