Answer:
the right answer is one solution
Sorry to hear that you already took the test. Here is how to do the problem:
2ˣ = 128
Let's take log base 10 of both sides.
For simplicity, we'll just use the symbol log to mean log₁₀
log (2ˣ) = log (128) Remember that log(yˣ) = x log(y)
x log (2) = log (128) Divide both sides by log(2) to get x by itself
x = log (128) ÷ log (2)
Answer:
B or 4![\sqrt[]{3}](https://tex.z-dn.net/?f=%5Csqrt%5B%5D%7B3%7D)
Step-by-step explanation:
I could be wrong as I'm very new to this math but I believe its 4
1$ is 100cents
45$ is 4500 cent
THE ORIGINAL price is $53
if 85% = $45
so 15%= ? cross multiply
45x15=85x$
675/85=x$
7.9 app8$ was discounted
original price=45+8=$53
in cent it is 5300 cents
