56. a

57. b

56. people bought soda and popcorn= 15

total people buy soda = 25

15/25 = 0.6

57. people didn't buy soda = 15

total people surveyed = 40

15/40 = 0.375 ( round off to 0.38 )

the thermometer is precise but not accurate

step-by-step explanation:

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10

x=5
