Answer:
680
Step-by-step explanation:
Your expression is 60+20x
I cant tell you if that is better than Platinum Gym or not because there is no detail as to what their deal is.
Step-by-step explanation:
The given equation is

As a check for exactness we have

Hence the given equation is an exact differential equation and thus the solution is given by
thus the solution is given by

Similarly we have

Comparing both the solutions we infer

Hence the solution becomes

given boundary condition is that it passes through (1,1) hence

thus solution is

Answer:
1. A 2. B
Step-by-step explanation:
Whatever happens to x must also happen to y.
For the first question, x is doubled, which means that the value of y is also doubled.
For the second question, if the value of x triples, then the value of y triples as well, which means that it would be multiplied by 3.
We can check to see if these two answers are true by inputting values into the equations.
For the first equation, let's use the example x = 2
y = 5(2)
y = 10
If the value if x doubled, it would become x = 4
y = 5(4)
y = 20
As you can see, when the value of x doubled from 2 to 4, the value of y also doubled from 10 to 20.
You can do something similar for the other equation.
75%
500-125 is 375
375/500 gives 3/4 which is .75
move the decimal over to the right twice to get 75%
