Use the guess-and-check method to find the solution of the equation.
3x + 5 = 32
X=

x = 9

Step-by-step explanation:

Just guess the answer for x. For example 8, 3 times 8 equals 24 and 24 plus 5 would equal 29 so that's incorrect. How about 9? 3 times 9 equals 27 and 27 plus 5 would equal 32 so the answer is, x = 9.

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

answer:   rotate 270° clockwise about (7, 1) and reflect across the line x = 7
