Hello,
I would love to answer but there is no screenshot to see!
3.(6^(12-10)) = 3× 6^2 =3× 36 =108
Your proportion should look something like this

After cross multiplication, you should end up with this equation

After dividing 4 on both sides, you should get that x=9
Answer:
x = 9
TH = 12
Step-by-step explanation:
since TM is half of HM, the equation is:
2(21 - x) = 3x - 3
42 - 2x = 3x - 3
45 = 5x
x = 9
TH = 21 - x
TH = 21 - 9
TH = 12
True. To solve for y you have to subtract 2 from both sides of the equation.
