Given the function f(x) = 3 x - 21 + 6, for what values of x is f(x) = 18?

IrinaK [193]

Answer:

X=2

If 21+6=27 then subtract what f(x) is (which is 18) from the 27. 27-18=6 then 3x2=6 so therefore your answer is 2. Hope this helps!!

Kanna Kamui let her DS charge for 108 minutes from 05%. What percent charge is Kanna's DS.

34kurt

Answer:

The percent charge of Kanna's DS is 50%

Step-by-step explanation:

we know that

A Nintendo DS takes 4 hours to charge fully (100%)

4 hours is the same that 240 minutes

using proportion

Find out what percentage represent 108 minutes

$\frac{100}{240}\ \frac{\%}{min} =\frac{x}{108}\ \frac{\%}{min}\\\\x=100(108)/240\\\\x=45\%$

Remember that

Kanna Kamui charge her DS from 5%

$5\%+45\%=50\%$

therefore

The percent charge of Kanna's DS is 50%
