Answer:
<u>Yes. I agree with his claim because the equation relating the miles left to walk and the number of miles left to walk is :</u> 
Step-by-step explanation:
Given :
- <em>It's a 21 - mile walkathon</em>
- <em>The rate at which he is moving is 3 miles per hour.</em>
Let the number of miles walked be 
;
∴,
The number of miles '
' left to walk will be : 
<em>Thus the time '
' for which he walked :</em>
:
∴
From these equations , we get :
Thus , when we compare this with 
,
<u>Thus this is an equation of a Line with slope -3.</u>
Answer:
1, 2, 3, 6, 13, 26, 39, and 78
Step-by-step explanation:
Answer:
x = 26 ft
Step-by-step explanation:
Using the right triangle formed by the sides 24 and 10 with hypotenuse x
Applying Pythagoras' identity, then
x² = 24² + 10² = 576 + 100 = 676 ( take the square root of both sides )
x = 
= 26
Answer:
length = (3*width) -2
length + 2 = 3*width
width = (length +2) / 3
2*length + 2*width = 68
OR: 2*length = 68 -2*width
If length = (3*width) -2 then
2*length = 6 * width -4
therefore,
6 width -4 = 68 -2 width
8 width = 72
width = 9
Since 2 length + 2 width = 68
then 2 length = 68 -2 width
2 length = 68 -18
length = 25
Step-by-step explanation:
Answer:
7m-7m=8n+8n
m=16n
Step-by-step explanation: U must first link the like terms so in order to do so u must bring over the 7m, now before u brought over the 7m it was a positive 7m now that your bring it over it turns negeitive and the same goes for the term 8n when u carry that term over it turns positive now dont let the subtraction sign foul u it still negative as long as its beside the term it is going to be negative guys dont forget that, now on to the next step after u cross over and change signs u start to work out now that the like terms are equal u dont need to worry about them because its given u the go ahead to workout so your main focus is on the subtracting the 7's which is 0 and leaves u with m u dont have to put them but i dont recommend it the u start on the next side u and the 8's which is 16 and u put bk the n u have to put bk the terms its important and thats how u get m=16n.
