Since the denominators are the same we can subtract the numerators

6t-8

-----------

3t-4

Factor out a 2 from the numerator

2(3t-4)

Answer

-2

Step-by-step explanation:

(8/3t-4) - (6t/3t-4)

Denominators equal, combine fractions:

8-6t/3t-4

Factor 8-6t: 2(4-3t)

2(4-3t)/3t-4

Cancel the numbers and you are left with -2

Hope this helped!

y(x) = ax + b

En que:

  • a eres lá inclinacion, o sea, lo que es pago por cada corte.
  • b eres el intercepto, o sea, lo pagamiento fixo por día.

y(x) = 25 + 50x

Order the numbers from least to greatest 0.8,8%,18%,1/8,8/18
inna [77]

Since you know more percentages than fractions, let's convert the fractions to percentages by dividing the numerator by the denominator, and then multiplying the answer by 100.

That means that 1/8 is 12.5% and 8/18 is 44.4%.

The correct order would be:

0.8%, 8%, 1/8, 18%, 8/18.
