1/2x + 2/3 = 3/4Find the xX=??

Mathematics
1 answer:
Burka [1]2 years ago
3 0

Answer: x=\frac{1}{6}

Step-by-step explanation:

To find x, we want to isolate x.

\frac{1}{2}x+\frac{2}{3} =\frac{3}{4}           [subtract both sides by \frac{2}{3}]

\frac{1}{2} x=\frac{9}{12} -\frac{8}{12}        [subtract]

\frac{1}{2} x=\frac{1}{12}                [multiply both sides by 2]

x=\frac{2}{12} =\frac{1}{6}

Now, we know that x=\frac{1}{6}.

Did you know it takes about 40 pounds of olives to make 3 liters of olive oil?
Eva8 [605]

Answer:

225 liters

Step-by-step explanation:

If it takes 40 pounds to make 3 pounds of olive oil, we set up this equation:

40 times what equals 3000?

Then, we multiply 3 by the number that we are looking for.

So, we do 3000 / 40 = 75 to get the number.

Then, we do 3 * 75 = 225.

Therefore, 3000 pounds of olives makes 225 liters of olive oil..

Help finding the sum
Mamont248 [21]
It is asking you to find the sum of k^2 - 1 from k=1 to k=4. Since that is only 4 numbers, calculating the sum by hand wouldn’t be that bad.

(1^2 - 1) + (2^2 - 1) + (3^2 - 1) + (4^2 - 1) = 26

The easier way to find the sum is to use a few simple formulas.

When we have a term that is just a constant c, the formula is c*n.

When we have a variable k, the formula is k*n*(n+1)/2.

When we have a squared variable, the formula is k*n*(n+1)*(2n+1)/6.

In this case, we have a squared variable k^2 and a constant of -1.

So plug in n=4 to the formulas:

4*5*9/6 - 1*4 = 26

The answer is 26
