2) which of these is a one-step equation?
A) x + 9 = 21
B) x = 11
C) 2x + 9 = 21

A

Step-by-step explanation:

Because the only step is to subtract 9 from both sides and then you get x=12

:)

there is no one step equation becuz

x+9 = 21

take 9 to the other side becos both are same variables then

21-9 = x

hence x= 12

next x=11 question can't be answered becuz this is not a complete question

2x+9 = 21

21-9 = 2x

12=2x

x=

12

2

hwnce 12/2 = 6 therefore x= 6

the answer is 9.8975

explanation:

when you multiply the "39.59" with the 25% it reduces it and shows its final discounted price. hope this !

step-by-step explanation:

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
