Dos campanas suenan a intervalos de 15 y 75 minutos respectivamente. ¿A qué hora sonarán juntas otra vez si empiezan simultáneamente a las
12 del mediodía?​

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3

you could deduce the conclusion directly using the facts pertaining to the specific situation.

hope this .

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:
