x and y varies directly and the equation will be: y=480.x
Step-by-step explanation:
We need to write the equation to represent the relationship between x and y
We can find if x and y varies directly or indirectly.
Checking if x and y varies directly
if x and y varies directly then y=kx or y/x = k then k is constant
if x=2 and y=960 then k is:
k=y/x= 960/2 = 480
if x=2 and y=960 then k is:
k=y/x = 1440/3=480
if x=2 and y=960 then k is:
k=y/x= 2880/6=480
if x=2 and y=960 then k is:
k=y/x=3840/8 = 480
Since y/x = 480 for every value of y and x in the table, so x and y varies directly and the equation will be:
y= kx
y=480.x

Is nora has 1/2 and she wants to share with 3 birds The answer is 0.4
Answer:
The two numbers are -365 and -1825.
Step-by-step explanation:
5x=y
x-y=1460
--------------
x-5x=1460
-4x=1460
x=1460/-4
x=-365
-365-y=1460
y=-365-1460=-1825
Answer:
<h2><em><u>
A to C = 25
</u></em></h2><h2><em><u>
A to B = 13
</u></em></h2><h2><em><u>
C to B = 37
</u></em></h2><h2><em><u>
</u></em></h2>
Step-by-Step Explanation:
<em><u>Perimeter</u></em> = 75
<em><u>Sides:</u></em>
2x + 3
3x + 4
2x - 9
<h2 /><h2><em><u>
1. Equal the sides added together to the perimeter</u></em></h2>
75 = 2x + 3 + 3x + 4 + 2x - 9
<h2><em><u>
2. Simplify Like terms</u></em></h2>
2x + 3 + 3x + 4 + 2x - 9 = 7x - 2
<h2><em><u>
3. Place the equation back together</u></em></h2>
75 = 7x - 2
<h2><em><u>
4. Isolate the variables and numbers</u></em></h2>
75 = 7x - 2
+2 +2
77 = 7x
<h2><em><u>
5. Simplify the equation</u></em></h2>
77 = 7x
/7 /7
<h2><em><u>
11 = x
</u></em></h2>
<h2><em><u>
6. Substitute the value of x into the side lengths.</u></em></h2>
2x + 3 = 2(11) + 3 = 22 + 3 = <em><u>25</u></em>
3x + 4 = 3(11) + 4 = 33 + 4 = <em><u>37</u></em>
2x - 9 = 2(11) - 9 = 22 - 9 = <em><u>13</u></em>
The answer is 6 and 1/15.
