Step-by-step explanation:
Ok, so, the question states that the distance driven is proportional to the time driven in hours. So, the x value would be hours driven, while the y-value would be the number of miles driven. So, in order to find the speed at which she is driving, you will want to divide the number of miles by the number of hours driving, or 180/3, You answer should be 60, or 60 mph is her speed.
X = 4
Explanation:
sqrt(x) + sqrt(5 + x) = 15 / sqrt(5 + x)
sqrt(5 + x)[sqrt(x) + sqrt(5 + x)] = 15
sqrt(5x + x^2) + 5 + x = 15
sqrt(5x + x^2) = 10 - x
Take square of both sides
5x + x^2 = (10 - x)^2
5x + x^2 = 100 - 20x + x^2
Cancel x^2
5x = 100 - 20x
25x = 100
x = 4
Answers:Architects always
Answer: B 15 miles per gallon
Explanation: To find a unit we must get the bottom number to 1 so we would divide 3/3 and repeat the process to 45 so it would be 45/3 which equals to 15 we can check our work by multiplying 15*3 which is equal to 45 have a nice day (:
