Answer:
I believe the last one is proportional
Step-by-step explanation:
simplify r/s and you will get your answer 5
I hope this helps :)
Given:
Since R is the midpoint of the line, we can set XR equal to RY and solve for x.
Now we know what x is. We can plug in x to RY and XR and then add it all together to find XY. Let's find XR:
Let's find RY now:
Since we know that:
We can plug in our answers:
Final answer:
Answer:
C. -13x0
Step-by-step explanation:
-13x0 will not give you a negative or positive number. This is because any number time 0 gives you 0, and zero is the only number that is neither positive nor negative. Every other expression will give you a nonzero number, which must be positive or negative.
The original price was 7.
Chloe got a 15% discount; this means she paid 100-15 = 85% of the price. Letting x be the price, Chloe paid 0.85x.
Denise got a 20% discount; this means she paid 100-20 = 80% of the price. Denise paid 0.8x.
We know that Chloe paid 35p more; this gives us the equation
0.85x = 0.8x + 0.35
We do not want a variable on both sides, so we subtract 0.8x from both:
0.85x - 0.8x = 0.8x + 0.35 - 0.8x
0.05x = 0.35
Divide both sides by 0.05:
0.05x/0.05 = 0.35/0.05
x = 7
Answer;
The answer is the second; log ₁₂1/4
Explanation;
From the laws of logarithms, given an expression in the form;
Log ₓ y, where x is the base and y is the number, we can apply the change of base formula to a logarithmic expression to get;
Log y/log x, which are to base 10
Thus; Log₁₂1/4 = log 1/4/ log 12
