Select the correct answer
Jessica is 5 years older than her sister Jenna Jenna tells her sister that in 5 years, she will be as old as Jessica was 5 years ago. If Jenna's age is x,
which equation represents the situation? How many solutions does the equation have?
OA X+5=(5-) - 5, which has one solution
OB. + 5 = (x + 5) - 5, which has infinitely many solutions
OC. X+ 5 = (x + 5) - 5, which has no solution
OD X+5 = (5 - X) - 5, which has infinitely many solutions
OE. (x + 5) + 5 =(x + 5) + 5, which has infinitely many solutions

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.
