Answer:
Answer 7
Step-by-step explanation:
This depends on setting up a proportion
5:45 :: 3: 3 + 2x + 10
You can reduce 5 / 45
5/45 = 1/9
1:9 :: 3:3 + 2x + 10
1:9 :: 3: 2x + 13
1/9 = 3/(2x + 13) Cross Multiply
2x + 13 = 3*9
2x + 13 = 27 Subtract 13
2x + 13 - 13 = 27 - 13
2x = 14 Divide by 2
2x/2 = 14/2 Divide
x = 7
Ratio of Circumference to it's diameter is always equal to pi. It is definition of pi (Like that's why it made), 'cause of constant value.
In short, Your Answer would be Option A) π
Hope this helps!
Answer:
A
Step-by-step explanation:
In normal situations, the answer would be B, but because of the context of the question, it talks about the phone's remaining battery life. Which means anything between 0 and12 will be our domain.
So we would want to isolate x. Start by multiplying both sides by -3. Since we are multiplying negative number, we flip the sign.
So that would be x ≥12. That means x should be greater than or equal to 12.
So now it's easy to answer.
C, D, E would be the answer.
