Help pleassssssssssss

A) The correct way to write 1/4 as a precent is 25%.

because....

1÷4= .25. and .25×100= 25%

b) The reporter most likely forgot to multiply by 100. The reporter instead just found what 1/4 was as a decimal, not a precent.

Answer:

$y = - 5$

Step-by-step explanation:

$- 5(y - 3) - 10 = - 6y$

➡️ $- 5y + 15 - 10 = - 6y$

➡️ $- 5y + 5 = - 6y$

➡️ $- 5y + 6y = - 5$

➡️ $y = - 5$
