Which statement is an example of causation? 1. Students who eat a good breakfast each day are more physically active than those who skip breakfast. 2. The increase in the number of ice-cream cones a vendor sells causes an increase in temperature. 3. The height of children increases as their running speed increases. 4. When it rains, the playground gets wet.

Let the number be x. Here x acts as any no u think of..right??

step 1: 2x

step 2: 2x+6

step 3: (2x+6)/2

step 4: (2x+6)/2 - x = (x+3) - x = 3 (cancelling 2 in (2x+6)/2,we get x+3 ..dnt get confused :D )

That's y d ans s always 3. :) :)

Stay blessed!!

Step-by-step explanation:

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
