1/2x + 1/4x = 16

3/4x = 16

Answer:

The value of the equation for x is x=\frac{64}{3}.

Step-by-step explanation:

Consider the provided equation.

\frac{1}{2}+\frac{1}{4}=16

We need to solve the equation for x.

Add the like terms as shown:

\frac{2x+x}{4}=16

\frac{3x}{4}=16

Multiply both the sides by 4/3.

\frac{3x}{4}\times \frac{4}{3}=16\times \frac{4}{3}

x=\frac{64}{3}

Hence, the value of the equation for x is x=\frac{64}{3}.

I need help graphing 2x - 6y = 42 I'm just really lazy​
solong [7]

Answer:

We can use slope intercept form to get the points needed. Y= -7+1/3x The points are (0,-7) and (3,-6)

Step-by-step explanation:

Subtract 2x from the left side and place it over to the right side with the 42. Now we have -6y= 42-2x. From here we divide by -6 and we get y= -7+1/3x. We know that are slope is 1/3 which the one is the rise and the 3 is the run. We also know that our y intercept is -7. We plot the points at (0,-7) and (3,-6)

"to replace a number with another number that tells about how many or how much". What is ths operation called?
Maru [420]

The operation is known as rounding of a number.

This means basically if i measure the temperature of a city and it comes out to be 22.9 degrees. I will round it of to 30 degrees or the amount of significant figures i am designated with.

Similarly if its 22.85 and i have to round of to 3 significant figures it becomes 22.9 degrees.

ROunding off is obviously done watching to which digit we have to.
