Answer:
(1)
And for this case we know the following condition "The length of the field is 7 yards less than quadruple the width" and we can write this :
And replacing into equation (1) we got:
Adding 14 in both sides we got:
And dividing 10 on both sides we got:
And then we can solve for X and we got:
Step-by-step explanation:
For this case we can set up the following notation:
X represent the lenght
Y represent the width
And since we have a rectangular playing filed the perimeter is given by:
(1)
And for this case we know the following condition "The length of the field is 7 yards less than quadruple the width" and we can write this :
And replacing into equation (1) we got:
Adding 14 in both sides we got:
And dividing 10 on both sides we got:
And then we can solve for X and we got:
(Notice that we always have ![y\ge6[tex].)Swap [tex]x](https://tex.z-dn.net/?f=y%5Cge6%5Btex%5D.%29%3C%2Fp%3E%3Cp%3ESwap%20%5Btex%5Dx)
and 
, then solve for :
(this is the inverse)
###
This inverse is valid only for 
. Why?
Suppose we take 
. Then
This would suggest that in the original equation, we should get 
when 
. But when we check this, we end up with
which is clearly not true.
Answer:
Each plane ticket was $189.3
Step-by-step explanation:
If all tickets were at the same price, and for five tickets the person paid $946.50, then to find out how much was each ticket, we simply have to divide this quantity by 5:
$946.5 / 5 = $189.3
Answer:
variable, In algebra, a symbol (usually a letter) standing in for an unknown numerical value in an equation. Commonly used variables include x and y (real-number unknowns), z (complex-number unknowns), t (time), r (radius), and s (arc length).
Answer:
Step-by-step explanation:
a: is not proportional
because you cant divide any of the tope numbers by the bottom numbers so u can leave the thing blanc.
b: is proportional
becuase you can divide the top and bottom by 30 so the answer is 30
hope this help :)
