If 14m-81 +5=21
what are the 2 possible
values of m?

6.9 or 7

Step-by-step explanation:

first 5 is subtracted from the 27

then the answer is 16 so you add 81

the answer is 97 so you divide it by 14

you'll get a value like 6.92857

m=97/14

Step-by-step explanation:

14m-76=21

14m = 21+76

M =97/14

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
