Answer:
x1 = 1/2 + 1/2t
x2 = 4 -2t
x3 = t
Step-by-step explanation:
Your answer is correct as far as it goes. The values of x1 and x2 also need to be expressed in terms of t.
x1 = 1/2 + 1/2t
x2 = 4 -2t
x3 = t
Given parameters:
Length of earring hook = 1.5cm
Length of given wire = 45cm
Dimension of the triangle = 3.2cm, 3.2cm and 2.1cm
Unknown:
Number of earrings that can be made from the wire = ?
To solve this problem, we need to calculate the total length of the earring we want to make.
Total earring length = Perimeter of earring + length of earring hook
= 3.2 + 3.2 + 2.1 + 1.5
= 10cm
Now the length of the wire is 45cm,
Number of earrings = = 4.5 earrings
But this is not reasonable, therefore, we can only forge 4 complete earrings from the given length with 5cm of wire remaining.
The number of earrings that can be made is 4.
