Start by making a formula for the price of each gym:
Powerhouse has a $100 entry fee, the constant, leaving $35 to go with your variable. Lets say m, which gives you the equation:
100 + 30m
Repeat the same thing for Megamuscle gym and you have the equation:
50 + 35m
Insert numbers for m (number of months) from 1 - 12 until you get a number for Lisa that is larger than Kelly's, which would be 11 months.
Kelly would have paid $430, with Lisa paying $435 in 11 months.

If 2/3 = x/y, then which of the following must be true?
Kazeer [188]

Correct option is third \frac{2+3}{3}=\frac{x+y}{y}

<h3><u>Solution:</u></h3>

Given that:

\frac{2}{3}=\frac{x}{y}

Need to check which of the expression from given four expressions will be true.

Let's first try to eliminate wrong options.

If we observe carefully, we can say that option 2 that is \frac{3}{2}=\frac{x}{y} is not correct as \frac{x}{y} must be equal to \frac{2}{3} and not \frac{3}{2}

Lets now modify given expression that is:

\frac{2}{3}=\frac{x}{y}

On adding 1 to both sides we get

\frac{2}{3}+1=\frac{x}{y}+1

=>\frac{2+3}{3}=\frac{x+y}{y} \text { which is same as third option. }

Hence correct option is third one that is \frac{2+3}{3}=\frac{x+y}{y}

Select all solutions to the solution to the following quadratic.<br> (x - 2)2 = 25
Makovka662 [10]

Answer:

x = 7,    x = -3

Step-by-step explanation:

(x - 2)^2 = 25

Take the square root of each side

sqrt((x - 2)^2) =±sqrt( 25)

x-2 = ±5

Add 2 to each side

x-2+2 = 2±5

x =  2±5

x = 2+5,  x=2-5

x = 7,    x = -3
