Answer:
4 hours
Step-by-step explanation:
In 6 hours, J paints 1 room
So, in 1 hour, J paints 1/6 th of the room
Using similar logic, in 1 hour, T paints 1/12 th of the room.
Working together in one hour, they paint (1/6+1/12) th =1/4 of the room.
1/4 of the room is painted in 1 hour
So, 1 room is painted in 1 1/4=4 hours
Step-by-step explanation:
Y= mx + c
2y = 3x - 8
2y = -3× - 8 ( divide all yerms by two )
y = <u>-</u><u>3</u><u> </u>× 4

Answer:
There should be 120 peanuts
Step-by-step explanation:
We can use ratio's to solve this problem
5 bags
---------------
75 peanuts
5 bags 8 bags
--------------- = ------------------
75 peanuts x peanuts
Using cross products
5x = 75*8
5x = 600
Divide each side by 5
5x/5 = 600/5
x = 120
Answer:
Below.
Step-by-step explanation:
Convert to sin's and cos's:-
(secx + tanx)(1-sinx)/cosx)
= ( 1/ cos x + sinx / cos x) * ( 1 - sin x )/ cos x)
= (1 + sin x) / cos x) * ( 1 - sin x ) / cos x
= (1 - sin^2 x) / cos^2 x
But 1 - sin^2 x = cos^2 x
so we have
cos^2 x / cos^2 x which = 1.
