1. The information, given in the problem, that you need to solve it, is:
 
 - <span>A steel bar that originally weighed 15.62 pounds.
 - Then i</span><span>t weighs 14.48 pounds.
 
 2. Therefore:
 
 15.62 pounds-----100%
 14.48 pounds-----x
 
 x=(14.48)(100)/15.62
 x=92.70%
 
 3. Now, you must substract both percents:
 
 =100%-92.70%
 =10.38%
 
 The answer is: 7.3%

The table tells us that the x coordinate. It also tells us that y is always x + 1.

For #1 you plot the coordinate (0, 1).
0 (the x coordinate) is given to us already.
1 (the y coordinate) is needed to be found by the equation.
You would then need to fill in the equation given with the x coorident. 
y = 0 + 1 
Then, solve for y.
0 + 1 = 1
The y coordinate is 1
Go to the horizontal line (x) and find 0.
Then go to the veridical line (y) and find 1.
Then match up the the x and y to plot the coordinate.

You would continue with this equation with the rest of the xs. 

This is a hard concept to explain in just words, so feel free to comment with any more questions. :D

Find the value of t needed to make the equation shown true. <br><br> 25t = 12.5
-Dominant- [34]

Answer:

1/2

Step-by-step explanation:

Hi Avahosel2020!

To find the value of t we need to simplify the equation:

25t = 12.5

To just get t, we must divide 25 on both sides:

\frac{25t}{25} = \frac{12.5}{25}

<u>We can move the decimal one spot over and add a 0 to the denominator:</u>

\frac{25t}{25} = \frac{125}{250}

t = \frac{125}{250}

Simplifying!

\frac{125}{250} = \frac{1}{2}.

Thus, t has the value of $\boxed{\frac{1}{2} }$.
