Answer:
<h2><em><u>x</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>3</u></em><em><u>,</u></em><em><u> </u></em><em><u>y</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>2</u></em></h2>
Step-by-step explanation:
<em><u>As</u></em><em><u> </u></em><em><u>due</u></em><em><u> </u></em><em><u>to</u></em><em><u> </u></em><em><u>congruency</u></em><em><u>,</u></em>
x + 3 = 3y
<em>[</em><em>By</em><em> </em><em>putting</em><em> </em><em>the</em><em> </em><em>values</em><em> </em><em>of</em><em> </em><em>x</em><em> </em><em>=</em><em> </em><em>3</em><em> </em><em>and</em><em> </em><em>y</em><em> </em><em>=</em><em> </em><em>2</em><em>]</em>
=> 3 + 3 = 3 × 2
=> 6 = 6
and,
x = y + 1
<em>[By putting the values of x = 3 and y = 2]</em>
=> 3 = 2 + 1
=> 3 = 3
<em><u>Hence</u></em><em><u>,</u></em><em><u> </u></em><em><u>proved</u></em>
Answer:
First - y=-2x+3
Second - y=-7+3

Answer:
a
Step-by-step explanation:i did it
City hall to post office = 6 1/2 miles = represented by f
city hall to library site = 1 1/4 miles = represented by d
library site to post office = unknown. = represented by e
City hall to library site PLUS library site to post office IS EQUAL to city hall to post office
d + e = f
1 1/4 + e = 6 1/2
find e.
e = 6 1/2 - 1 1/4
e = 13/2 - 5/4
e = (13*2)/(2*2) - 5/4
e= 26/4 - 5/4
e = (26-5)/4
e = 21/4
e = 5 1/4 distance from library site to post office.
To check:
d + e = f
1 1/4 + e = 6 1/2
1 1/4 + 5 1/4 = 6 1/2
6 2/4 = 6 1/2
6 1/2 = 6 1/2
To find the mean (average), u add up all ur numbers, then divide by how many numbers there are.
mean = (5 + 12 + 1 + 5 + 7) / 5 = 30/5 = 6
To find the mode (and there does not have to be one)...u find the number that is used the most. That number would be 5...because it is used twice, whereas, the other numbers are just used once.
