is this right? 2/3+3k/4=71/12 y=12/8
2/3+3k/4=71/12 and y=12/8 is this right?????
does anyone know??????????
i give up no ones answering me ugh:(
2/3 + 3k/4 = 71/12,
Multiply both sides by 12:
8 + 9k = 71,
9k = 71 - 8,
9k = 63,
k = 7.
To determine if the equation 2/3 + 3k/4 = 71/12 is correct, we need to check if it satisfies the equation when k = 12/8.
Let's substitute k = 12/8 into the equation:
2/3 + 3(12/8)/4 = 71/12
First, simplify the expression 3(12/8) by multiplying 3 and 12/8:
2/3 + (36/8)/4 = 71/12
Next, simplify the expression (36/8)/4 by dividing 36/8 by 4:
2/3 + 9/8 = 71/12
Now, let's find a common denominator for 3 and 8:
The least common multiple of 3 and 8 is 24, so let's convert 2/3 and 9/8 to have a denominator of 24:
(2/3) * (8/8) = 16/24
(9/8) * (3/3) = 27/24
Now the equation becomes:
16/24 + 27/24 = 71/12
Combine the fractions on the left-hand side:
(16 + 27)/24 = 71/12
Simplify further:
43/24 = 71/12
The equation 2/3 + 3k/4 = 71/12 is not true when k = 12/8, as the left and right sides do not match.
As a result, the statement "y = 12/8" is unrelated to the original equation and does not affect its accuracy.
