Select all of the equations that represent linear relationships.5 + 2y  = 13y =  +7y  – 5 = 2(x  – 1)  =  x  + 7x  = –4

1,3,4,and 5 are all linear

Step-by-step explanation:

Just took it. Edg 2020. Hope this helps :)

5+2y=13 is linear

y=+7 is linear

y-5=2(x-1) is linear

=x+7 idk this is not complete so i cant answer it

x=-4 is linear

HOPE IT HELPED<3 tell me if I am wrong.

Step-by-step explanation:

37.5% are male

62.5% are female

Step-by-step explanation:

in total 120 teachers (45 male+75 female)

therefore:

for male

120 - 100%

45 - x%  (we need to find x)

by using the butterfly method (or cross multiply) we get:

120x=100*45

x=4500/120=37.5% (male teachers)

we do the same for female but instead of using 45 we will use 75(the quantity of female theachers in school)

120x=100*75

x=7500/120=62.5%
