Solve <span>6x+4x-6=24+9x. Combine all the x terms on one side and all the constants on the other:
10x-9x = 24+6, or x = 30. ONE soution.
Solve </span><span>4x+8=2x+7 +2x-20. Combine all the x terms on one side and all the constants on the other: 4x - 2x - 2x = 7 - 20 - 8 => 0 = -21
This is NEVER true, so </span><span>4x+8=2x+7 +2x-20 has NO SOLUTION.
Please try solving equation B yourself. Then I'd gladly comment on your work.</span>
Answer:
The Best answer will be D having to add 7 then subtracting 8, becoming -1, then dividing to become D.
Step-by-step explanation:
The answer would be 17/50. You just divide the percent by 100, then simplify
60% or 3/5 of the tank will be filled in an hour.
The pump will fill 2/5 of the tank in 2/3 hours.
In order to find out how much of the tank will be filled in an hour, use direct proportion and assume portion of the tank that will be filled up in an hour is x.
<em>2/5 of tank : 2/3 hours </em>
<em>x of tank : 1 hour </em>
Cross multiply to get:
2/3x = 2/5
x = 2/5 ÷ 2/3
x = 2/5 x 3/2
= 0.6 of the tank
= 60%
= 3/5 of tank
In conclusion, 60% of the tank will be filled in an hour.
