Answer:
1/64
Step-by-step explanation:
Given the expression
3+4√4y = 4
4√4y = 4-3
4√4y = 1
√4y = 1/4
Square both sides
(√4y)²= (1/4)²
4y = 1/16
y = 1/16 * 1/4
y = 1/64
Hence the value of y is 1/64
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.

Answer:
6
Step-by-step explanation:
Deisha's build rate = 1 fence per 15 hours = 1/15 fences per hour
Travis's build rate = 1 fence per 12 hours = 1/12 fences per hour
Working together, their combined rate is 1/15 + 1/12 = 3/20 fences per hour
So it takes them 20/3 = 6 2/3 hours per fence
