Jenna's age Jessica's age
today x x + 5
in 5 years x+5
5 years ago x + 5 - 5
Equality x + 5 = x + 5 - 5
=> x + 5 = x
The equation is x + 5 = x
That equation has not any solution, because it reduces to 5 = 0, which is an absurd.
So, the conclusion is that information given by Jenna is wrong.
It is logical: if the difference of the ages is 5, in five years Jenna will have 10 years more than what her sister had 5 years ago, no 5 as she told Jessica.
Answer:
C
Step-by-step explanation:
Consumed = 1500
Burned = 400
Calorie Count total = 1500 - 400 = 1100
His target is 1900, so he will need 1900 - 1100 = 800 calories to consume more
So, 1100 is NOT a viable solution because he will go over 1900 if that happens. Hence, C is the correct choice.
Answer:
D. d = 
Step-by-step explanation:
Use the distance formula: d = 
The two points are (6, -2) and (3, -9)
Plug the values into the formula:
d = 
Simplify
d = 
d = 
d =
I hope this helps :))
Answer:
The magnitude of the necessary lifting force is 7.95N
Step-by-step explanation:
Force = mv^2/r
mass (m) = 2.00105kg, velocity (v) = 123m/s, radius (r) = 3810m
Force = 2.00105×123^2/3810 = 30273.89/3810 = 7.95N
