Let n represent an unknown number. if n is double the size size of 10, which equation can be used to find it? a. 10 + 2 = nb. 10 - 2 = nc. 10 × 2 = nd. 10 ÷ 2 = nplz .. i'm going thru hell..

C. 10 × 2 = n

Step-by-step explanation:

n = unknown number

"Is"  means equals

"Double" means times 2

if n is double the  size of 10,

n = 2* 10

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
