Answer:
x = ±9
Step-by-step explanation:
Isolate 2x^2 by subtracting 65 from both sides:
2x^2 = 162
Then x^2 = 81, and x = ±9
The question is what is the solution to the following equation:
: How many times 2/3 have to be used to give 2?
We solve this by multiplying both sides of the equation by 3 first, to get rid of the fraction:
now, let' divide it by2:
x=3
so she needs to do this three times.
Answer: 27
Step-by-step explanation:
Hi, to answer this question we have to apply proportions:
Michael hits the bulls-eye on a dart board 18 out of 30 tries
The proportion is: 18 hits / 30 times= 18/30
For 45 times:
x hits / 45 times
Where x is the number of hits out of 45 times.
So:
18/30 = x/45
Solving for x:
[18/30] 45 = x
x =27
Feel free to ask for more if needed or if you did not understand something.
bearing in mind that the derivative of s(t) is s'(t) = velocity, thus
namely a negative rate, so the object is slowing down to a stop.
