Jamie owns about 3 times as many books as carly. jamie owns 42 books. write an equation and use it to estimate the number n of books carly owns

y = 3n where y is the number of books owned by Jamie which is equal to 42

Step-by-step explanation:

If Jamie owns about 3 times as many books as Carly. It means that the number of books owned by Jamie is a function of the number of books owned by Carly.

If Carly owns n number of books, and Jamie owns y number of books then,

y = 3n

If Jamie owns 42 books then Carly owns

42 = 3n

n = 42/3

n = 14

Carly owns 14 books

were is the equation

26 is 33.33% of 78

step-by-step explanation:

26 is what percent of 78?

26 is p% of 78

equation: y = p% * x

solving our equation for p

p% = y/x

p% = 26/78

p = 0.3333

convert decimal to percent:

p% = 0.3333 * 100 = 33.33%
