Answer:
72.5%
Step-by-step explanation:
29 is the number of students showed up
40 are the number of students in the class
= 29/40 × 100/100
= 29/2× 5/100 we have simplified the fraction
=(29/2× 5)/100
=( 145/2) × 100
=72.5/100
=72.5%
Answer:

I. xy + 2y=3 Not linear equation because is grade 2 equation (xy).
II. x-2y = y Are linear equations in two unknowns (x and y).
III. 3x + 2y = 5 Are linear equations in two unknowns (x and y).
