Answer:7c +6d +12
Step-by-step explanation:3c + 7 + 12d - 6d + 4c + 5 = ?c + ?d + ?
3c + 4c +12d - 6d +7 +5
= 7c +6d +12
You combine like terms which are 3c and 4c which gives you 7c .Next you combine 12d and 6d but this time u need to subtract since it has subtact sign in between 12d and 6d which gives you 6d.After that you combine 7 and 5 which u get 12 .Lastly you put all of the tersm together which are 7c and 6d and 12 which get you 7c +6d +12 as your equivalent expression.
Please give brainliest if it helps :)
I think u have to add the fractions or multiply them
(z + 6) / 3 = 2z / 4
this is a proportion, so we cross multiply
(3)(2z) = 4(z + 6)
6z = 4z + 24
6z - 4z = 24
2z = 24
z = 24/2
z = 12 <==
DONT CLICK ON THE LINKS! It’s 8.750 BY THE WAY the radius is half the diameter so just add the radius by itself or multiply by 2
