Step-by-step explanation:
y cannot be determined from the information given
Answer:


Step-by-step explanation:
Represent trees with T and wreaths with W
Given


Solving (a): Cost of W
Substitute 3 + 4 * W for T in the second equation


Collect Like Terms


Divide through by 6


Hence, each wreath costs $16
Solving (b): Cost of T

Substitute 16 for W



Hence, each tree costs $67
The elevations of four points below sea level are -47 feet, -24 feet, -8 feet, and -18 feet.
The elevation of the point closest to sea level is feet
-8 ft
elevation of the point farthest from sea level is feet.
-47 ft
closet to sea level to farthest to sea level
-8ft , -18ft , -24ft , -47ft
The mode of this is 8,10, and 5



<u>By first equation,</u>


<u>Now, we can find the original value of y.</u>








<u>Now, we can find the original value of x.</u>




Therefore, the values of x and y are 5 and 2 respectively.
