Answer:
<u>The knitting club has 7 members </u>
Step-by-step explanation:
1. Let's check the information provided to us to answer the question correctly:
Cost of new patterns book = US$ 3.50
Cost of set of knitting needles for each member = US$ 3.20
Cost of set of a ball of yarn for each member = US$ 3.20
2. Write and solve an equation to determine how many members the knitting club has.
Number of members of the knitting club = x
For solving for x, we can use this equation:
3.50 + 3.20x + 5.40x = 63.70
8.60x = 63.70 - 3.50
8.60x = 60.20
x = 60.20/8.60
x = 7

-3 or 4.
Answer:
4
Step-by-step explanation:
the third angle of the inner triangle is defined by using the rule that the sum of all angles in a triangle must be 180 degrees. let's call this angle a
180 = 48 + 16x + a
132 - 16x = a
and then we know that both angles, 28x and a together must also be 180, as they are complementing each other to cover the whole top of the base line.
so,
28x + 132 - 16x = 180
12x = 48
x = 4
