The answer to your question is: .75 = 3x - .03

How to solve it:

x = the cost of a pack of gum twenty years ago

.75 =  3x - .03
+ .03      + .03

.78 = 3x
 / 3    / 3         

.26 = x

If a pack of gum now costs 75 cents, which is 3 cents less than three times what a pack would have cost 20 years ago, then a pack of gum would have cost 26 cents.

If you meant to write this;Nisha and Marcie Drive 20 miles from their sisters to hoodoo to go skiing. The speed limit is 55 miles per hour. It snowed all night, and the safe speed to drive is 40 miles per hour. Explain how you can determine how many more minutes it takes to drive 20 miles at 40 miles per hour in a 55 miles per hour zone.
If you drive 20 miles at 40 mile per hour, then 20 miles divided by 40 miles equals .5.5 times 60 minutes (one hour) is 30 minutesIf you drive 20 miles at 55 mile per hour, then 20 miles divided by 55 miles equals .3636.3636 time 60 minutes (one hour) is 21.8 minutes30 minutes at 40 mph minus 21.8 minutes at 55 mph is 8.2 minutes faster

sveticcg [70]

Answer:

\frac{x}{y}=1.3

Step-by-step explanation:

<u>Informação recuperada:</u>

(UFRGS) Se 10x = 20y , atribuindo 0,3 para log 2 , então o valor de x/y é

1) Primeiro, passando o 10 para o 2º membro como base do logaritmo:

10x=20y \Rightarrow x=log_{10}20y

2) Aplicando a propriedade do produto de logaritmo:

log(AB)= logA+logB

x=log_{10}20y \Rightarrow x=log(2+10)y\Rightarrow x=(0.3+1)y \Rightarrow x=1.3y

3)  Como quero o quociente divido ambos os lados por y

\frac{x}{y}=\frac{1.3y}{y}\Rightarrow \frac{x}{y}=1.3
