Answer:
9x^4=6,561x
6x^2=36x
6561x+36x=6597x
Step-by-step explanation:
9x to the 4th power is just 9x9=81x9 and so on and the same goes for 6 then you just add them. Not Sure if this is the way you needed but feel free to ask anything.
-- Subtract 9 from each side of the equation.
-- Divide each side by 4 .
-- The value of 'n' is right there, and you did it all on your own !
Answer:
a) t=b-5 b) j=b+3+2
Step-by-step explanation:
t is tina, we don't know how much Ben scored so we use b, then subtract 5 because tina got 5 less. same thing for Juan but we add the 3 points he got more than Ben and the 2 extra credit points
D,A,B,C i think this is correct !
Here's how one would solve it:
17 + 3x2 = 6x
17 + 6 = 6x
23 = 6x
x = 23/6
There's only one solution.
