Answer:
r = -1/2
Step-by-step explanation:
3(5 + 4r) = -18r
15 +12r = -18r by distributive property
15 = -12r - 18r
15 = -30r
r = - 1/2r
Answer:
x^(1/2)
Step-by-step explanation:
For this, we need to understand exponent rules. This one is like this, "A power to a power, you multiply the exponents". This is simply, because this expression would be equivalent to 3 base terms:
(x^(1/6))^3 = (x^(1/6)) * (x^(1/6)) * (x^(1/6))
And when you perform this multiplication "Powers of like bases, you add the exponents", you will get the following
(x^(1/6)) * (x^(1/6)) * (x^(1/6)) = x^(1/6 + 1/6 + 1/6) = x^(3/6) = x^(1/2)
Hence, this expression simplifies to x^(1/2).
Cheers.

Answer:
$72.50
Step-by-step explanation:
To find the price of the original Blu-ray player, we first divide the price that Rachel paid by 8 , then multiply the result by 10 to get the full price.
58 / 8 = $7.25
$7.25 x 10 = $72.50
Not great at ratios but Im pretty sure it's...
15:6 simplifies to 5:2 because you can divide them both by 3
