The record low temperature in Wyoming is -63° F. How many degrees below 0 is this?

Step-by-step explanation:

It's 63 degrees F below zero.

Temperature is measured on a number line. You can get confused by the freezing point of water which is +32.

0 represents the coldest temperature that those who used Fahrenheit thought the temperature would go. Tell that to the people who lived through - 63.

So  the answer if - when the temperature goes below 0.

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

25/6

step-by-step explanation:

you multiply 4 by the denominator (4*6=24) and add it to the numerator which makes it 25/6.
