Answer: Weight of Charles = 177.5 pounds
Weight of dos = 22.5 pounds.
Step-by-step explanation:
Let x = Weight of Charles
y = Weight of dog.
As per given , we have the following system of linear equation :
We can write (ii) as :
Subtract equation (iii) from (i) , we get
Put this value in (1) , we get
Hence , Weight of Charles = 177.5 pounds
Weight of dos = 22.5 pounds.

Answer:
x = 10.75
Step-by-step explanation:
To find the value of x, we need to know the equation for the perimeter of a rectangle. This equation is:
P = 2L + 2W
Where P is the perimeter, L is the length, and W is the width.
We are given P = 84, L = 3x -1 , and W = x. Now we just plug these values in and solve for x.
P = 2L + 2W
84 = 2 ( 3x - 1 ) + 2 ( x )
84 = 6x - 2 + 2x
84 = 8x - 2
86 = 8x
86 / 8 = x
43 / 4 = x
(40 + 3) / 4 = x
10.75 = x
Hence, the value of x = 10.75.

<span>Using
the information give, we can create two equations with two unknows as shown
below:
50U+20E=10680 and
U+E=280.
Where U represents Unlimited ride passes
and E represents Entrance-only passes. We can use the second equation to find
the value of U in relation to E. So that U is represented as U=282-E. We then
proceed to substitute E in the first equation using the value we assigned it
in relation to U so that we can have only one unknown value in the equation.
So 50U+20E=10680 becomes 50(282-E)+20E=10680. Simplifying this equation,
14100-50E+20E=10680. Putting the unknowns on one side we end up with
14100-10680=50E-20E. Solving for E, we end up with E=114. U can also be
calculated by substituting the already known value of E in the simpler
equation U=280-114. This means that the value of U is 168. So the number of
unlimited passes that were sold is 168</span></span>
