Answer:
x ≈ 2.91644500708
Step-by-step explanation:
The equation can be simplified to ...
2(4^x) +4(4^x) = 342
6(4^x) = 342
4^x = 57
Taking logarithms, we get ...
x = log₄(57) = log(57)/log(4)
x ≈ 2.91644500708
Your answer here is t = -20
-8 = 2/5t
Equation
2/5 = 0.4
2 divided by 5 is 0.4
-8 / 0.4 = -20
Divide -8 by 0.4 which is -20
Yes it did occur it was just a very long time ago. As the earth grew and developed the countries separated and that is why they are spread all over the world now. Hope this helps.
I don’t know the rest, but I think the 1st and 3rd ones are true! I hope this helps some, I’m sorry if it’s incorrect!
30% off 25: multiply 25 by .30 to find 30%: 7.5. Now subtract that from the sales price: 25-7.5=17.5
Do the same for store B: .40•30=12. 30-12=18.
So store A is better by $.50 :) hope this helps :)
