Answer:
40 people
Step-by-step explanation:
One for each person
==> 225 is 75% of 300 .
==> 225 is 25% smaller than 300 .
==> 225 is 3/4 of 300 .
==> 300 is 4/3 the size of 225 .
==> 300 is (33 and 1/3)% bigger than 225 .
==> 225 is 75 less than 300 .
==> 225 has 10 fewer factors than 300 has.
==> 300 has 2.25 times as many factors as 225 has.
==> 225 and 300 have 5 common factors.
==> The greatest common factor of 225 and 300 is 75 .
Answer:
x = -3 x=8
Step-by-step explanation:
(x+3)(x-8)=0
Using the zero product property
x+3 =0 x -8 = 0
x = -3 x=8
Answer:
y=17/3
Step-by-step explanation:
So you should make one -3y positive to cancel them out.
So multiply 2x-3y=43 by -1 and you get
-2x+3y=43
4x-3y=83
now +3y -3y cancel each other out
4x-2x=83-43
2x=50
x=25
Now enter 25 into the equation as x to find y
4(25)-3y=83
100-3y=83
100-83=3y
3y=17
y=17/3
