Answer: old machine 150, new machine 280
Step-by-step explanation:
given data:
Old machine = 25t
New machine = 35t
where t = hrs
we dont know the time for old machine so we assume it to be ( t ),
while that of the new machine is ( 14-t ) hours for new machine, and sum of 430 components.
therefore;
25t +490 - 35t = 430
-10t = -60
divide both sides by -10
t = 6 hours for the first machine.
6hrs * 25 components /hr
= 150 component parts For old machine.
for new machine
= 14 - t ........... eq1.
where ( t = 6 ), substitute t into the equation
= 14 - 6
= 8 hours for the second machine
= 8 * 35
= 280 components parts
Find a common denominator. for example the third question is 2/3-2/5. the common denominator would be 15 because both are divisible by 15. since you multiply three, 5 times to get 15 you multiply 2 by 5 which is ten (new fraction is 10/15). then the other is 2/5 so same thing with the other one it takes three fives to get to 15 so its 2 times 3 which is six (new fraction is 6/15) you have to qual out each side. 10/15-6/15 is 4/15

Answer:
The possible rational roots are

Step-by-step explanation:
We have been given the equation 3x^3+9x-6=0 and we have to list all possible rational roots by rational root theorem.
The factors of constant term are 
The factors of leading coefficient are 
From ration root theorem, the possible roots are the ratio of the factors of the constant term and the factors of the leading coefficient. We include both positive as well as negative, hence we must include plus minus.
