All numbers divisible by 100 are divisible by 25.
all numbers divisible by 25 are divisible by 5.
conjecture: all numbers divisible by 100 are divisible by 5.

use deductive reasoning to verify the conjecture, or provide a counterexample if the conjecture is false.

a.
true; law of detachment
b.
true; law of syllogism
c.
false; 75 is divisible by 5, but 75 is not divisible by 100
d.
false; 200 is not divisible by 5

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
