Answer: 150
Step-by-step explanation:
Answer:
(1) x = (1/3)a
Step-by-step explanation:
Note that 8 = 2^3 and 1/2 = 2^(-1). So, 8^(x-2a) = 2^(3(x-2a)) = 2^(3x-6a) and (1/2)^5a = 2^((-1)(5a)) = 2^(-5a). Setting these equal we get: 2^(3x-6a)=2^(-5a). We can notice that the exponents must be equal, so 3x-6a = -5a. Adding 6a on both sides, we get: 3x = a. Then, we divide by 3 on both sides and get: x = (1/3)a
i hope this helps!!! :)
54.16 is more precise because it has more digits
Answer:
5 1/2 cups
Step-by-step explanation:
For this you just need to do 11/2
To check your answer you can use the inverse operation and flip it to make it 2x5.5=11
Answer:
x = ![\sqrt{84}](https://tex.z-dn.net/?f=%5Csqrt%7B84%7D)
Step-by-step explanation:
According to Pythagorean Theorem, the square value of hypotenuse is equal to sum of square value of two legs:
x^2 + 4^2 = 10^2
x^2 + 16 = 100 subtract 16 from both side
x^2 = 84 find the root of both sides
x = ![\sqrt{84}](https://tex.z-dn.net/?f=%5Csqrt%7B84%7D)
