Consider the following systems of linear equations ax = b. manually solve the systems and classify them based on the existence/type of solution. a) 2x - y+z=1 x+y-z= 2 3x - y+z=0 b) – xy + x2 +3x3 =-2 x2 + 2x2 = 4 c) x – 2y =-1 2x + 3y = 7 d) x-2y=-1 -x +2y = 7

in 4 days he will run   12/14

step-by-step explanation:

42%

step-by-step explanation:

we know,

total people = 60

total males = 25

percentage of males

= 25/60 × 100

= 25/6 × 10

= 25/3 × 5

= 125 / 3

= 41.

rounding of = 42%
