Answer:
-2
Step-by-step explanation:
the answer is -2, as shown
We have this equation:
First, combine both logarithms using the multiplication property and simplify the expression.
Now, use the definition of logarithm to transform the equation.
Finally, use the quadratic formula to solve the equation.
With this, we can say that the solution set is:
We cannot choose x = -100 as a solution because we cannot have a negative logarithm. The only solution is x = 1.
This is obviously B, you can get the answer through guess and check with a calculator or just take everything out that makes no sense at all like D and A and then figure out your final answer with the last 2 that make sense
Answer:
Samadhi paid $ 1.32 more than Kerega.
Step-by-step explanation:
We were given the price of chocolate per kilogram, but Karega and Samadhi bought it in grams, so in order to solve this question we will convert the amount they bought from grams to kilograms, to do that we divide the value by 1000. So we have:
Karega = (25 grams)/1000 = 0.025 kg
Samadhi = (100 grams)/1000 = 0.1 kg
In order to find how much each paid for their chocolate we have to multiply the amount the bought in kg by the price per kg. So we have:
Kerega = (0.025)*17.6 = $ 0.44
Samadhi = (0.1)*17.6 = $ 1.76
To know how much more Samadhi paid we have to subtract the amount she paid by the amount Kerega paid. We have:
difference = Samadhi - Kerega = 1.76 - 0.44 = $ 1.32
Samadhi paid $ 1.32 more than Kerega.
