Answer:
12 x -7 = -84 12 + (-7) = 5
Step-by-step explanation:
Answer:
it is 20%
Step-by-step explanation:
easy
1) distribute 2 to each term within the parentheses
2) combining like terms ( which means subtract a 6-2)
3) subtract 4 from both sides of the equation
4) divide both sides of the equation by 4
Final answer should be ( x = 1/4 )
To fill:
6 hours = 1 tank
1 hour = 1/6 tank
To drain:
It takes 4 times as long, therefore 4 x 6 = 24
24 hours = 1 tank
1hour = 1/24 tank
If both pipes are open
1 hour = 1/6 - 1/24 = 1/8 tank
1/8 tank = 1 hour
8/8 tank = 1 x 8 hour
1full tank = 8 hours
Answer:
Step-by-step explanation:
To figure out the midpoint, you need to plug the coordinates into the midpoint formula.
M (x1 + x2 / 2, y1 + y2/2)
M [ 2 + (-3)/2, 5 + 9/2]
M ( -1/2, 7)
