Answer:
Step-by-step explanation:
If J can paint a room in 3 hours, in 1 hour she gets
of the job done.
If A can paint a room in 4 hours, in 1 hour she gets
of the job done. We need to find out how long it takes them if they paint together. The equation for this is:
where x is the number of hours it takes them to get the job done together. Multiply everything through by 12x to get
4x + 3x = 12 so
7x = 12 and
x = 1.7 hours to get the room painted together.

Answer:
{x | x < - 35 / 2}
Step-by-step explanation:
-4x / 7 > 10
Multiply both sides by 7
-4x /7 * 7 > 10 * 7
-4x > 70
Divide both sides by - 4
-4x / - 4 > 70 / - 4
x < - 35 / 2 (inequality sign changes)
Answer: 3/10
Step-by-step explanation: by adding the number of coins up you get 10 coins, then minus how many pennies and nickels there are then it comes out with a proper fraction, no simlifying needed :)
