9514 1404 393

Answer:

  see below

Step-by-step explanation:

It is easiest to compare the equations when they are written in the same form.

The first set can be written in slope-intercept form.

  y = 2x +7

  y = 2x +7 . . . . add 2x

These equations are <em>identical</em>, so have infinitely many solutions.

__

The second set can be written in standard form.

  y +4x = -5

  y +4x = -10

These equations <em>differ only in their constant</em>, so have no solutions.

__

The third set is already written in slope-intercept form. The equations have <em>different slopes</em>, so have exactly one solution.

The table shows the American League batting champions for the years 1999–2003. The sum of these five batting averages is 1.754.
fgiga [73]
The answer is <span>A. .357 + .372 + .350 + .349 + x = 1.754; .326 
</span>
x1 - average of <span>1999 Nomar Garciaparra Boston
</span>x2 - average of 2000 Nomar Garciaparra Boston
x3 - average of <span>2001 Ichiro Suzuki Seattle 
</span>x4 - average of Manny Ramirez Boston  
x - average of <span>2003 Bill Mueller Boston 

</span><span>The sum of these five batting averages is 1.754:
x1 + x2 + x3 + x4 + x = 1.754

From the table:
x1 = 0.357
x2 = 0.372
x3 = 0.350
x4 = 0.349
x = ?

<u>0.357 + 0.372 + 0.350 + 0.349 + x = 1.754</u>

1.428 + x = 1.754
x = 1.754 - 1.428
<u>x = 0.326</u></span>

Find the scale ratio for the map described below. 1 mm ​(map) equals 500 m ​(actual) The scale ratio is 1 to nothing.
lana66690 [7]

Answer:

1:500000

Step-by-step explanation:

1 mm ​(map) equals 500 m ​(actual) .

Let's convert 500 m to mm.

1m = 1000mm

500m = 500000 mm

So 1mm to 500000mm on a scale is

1:500000

So it's all about converting the metre to million metre then doing the ratio.

In this case we are not to divide anything because it's already in 1.

So it's 1mm on paper then 500000mm on actual.

Thank you
