6x+9=3x+12
6x-3x=12-9
3x=3
X= 3
I hope this helps :)!
Think of it this way:
_ _ _ (3 digit number)
for the first blank you could have 7 possibilities
for the second blank you could have 6 possibilities
for the third blank you could have 5 possibilities
because each time you fill in a blank one number is removed from the list of possibilities
7×6×5=210. there are 210 possibilities
Answer:
the value of x=9 and AB(h)=9.396
Answer:
18
Step-by-step explanation:
Subtract 6 from both sides so the equation becomes 1/9x=2. Multiply by the reciprocal on both sides (9)1/9x=2(9).
This cancels out to x=18
