Answer:

\large\boxed{x=20}

Step-by-step explanation:

How to find the value of x in an equation?

To find the value of x, or any other variable, use Addition, <em>Subtraction</em>, <em>Multiplication</em> or Division. The entire process of solving an equation really boils down to these four mathematical operations.

The first operation to be used in the equation 4=\frac{x}{5} is <em>Multiplication</em>. I am going to multiply 5 by both sides. I will end up with this as my result:

20=x, or x=20.

Determine the value of x for which rls if<br> .<br> m2i = 80 - X; and<br> mz2 = 90 - 2x<br> .
Slav-nsk [51]

Answer:

  x = 10

Step-by-step explanation:

For the lines to be parallel, the two angles must have the same measure:

  80 - x = 90 - 2x

  x = 10 . . . . . . . . . add 2x-80

The value of x must be 10 to make the lines parallel.

I'll mark as Brainliest, Please answer ASAP, Ihave MCAS tomorrow. How could this be true?? Please Explain.​
Vaselesa [24]

Answer:

See below

Step-by-step explanation:

The number of loaves of bread remaining can only go as low as ZERO (you can't have negative loaves) ...and can only go as high as when h = 0

     so    0 = 42-3.5 h    

             3.5 h = 42

                h = 12       and   min is  h = 0   ( when there are 42 loaves to start)

So:

<u>0≤ h ≤ 12 </u>

What is an estimation strategy<br> This is for 6th grade math please help
Lunna [17]

Answer:

Estimation is a mental process of coming up with an answer that is relatively  close, to allow decisions to be made. The types of estimation are quantity, computation and measurement.

An estimation strategy is simply coming up with a good estimate based on evidence and already known facts. Coming to a conclusion as close to the real answer as you can. It can also be called an educated guess.
