The neighborhood park sells a membership to use the recreation center for $5 each time you use the center plus a $50 flat fee, or you can pay $10 each time you use the
center.
Which equation would you use to determine how many times you must use the
center to justify buying the membership?

A. 5x + 50 = 10x
B. 5x + 50 = 5x
C. 10x + 50 = 5x
D. 10x - 50 = 5x

omg what happend to your question? if you could edit this question i can

step-by-step explanation:

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
