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
Answer:
The values of y would be -9 and 15
Step-by-step explanation:
we know that
the formula to calculate the distance between two points is equal to
we have

S(-2,3) and T(3,y)
substitute the given values in the formula and solve for y
squared both sides
take square root both sides




therefore
The values of y would be -9 and 15
Answer:
36 degrees
Step-by-step explanation:
The whole shape is 90 degrees.
90 - 54 = 36
36 degrees
Answer : - 4 + 3 = - 1
- 2 + 3 = 1
By half gives - 1/2 and 1/2
So midpoint (-1/2, 1/2)
