The total number of nickels we have is 15.
Given we have 27 coins, made up of nickels, dimes and quarters.
there total value is $3.30
we have 3 times as many quarters as dimes.
total nickels = ?
let, x = number of dimes
3x = number of quarters
y = number of nickels
then, x ₊ 3x ₊ y = 27
therefore, 4x ₊ y = 27 .. eq(1)
total value of coins in cents = 330
10(x) ₊ 25(3x) ₊ 5(y) = 330
10x ₊ 75x ₊ 5y = 330
85x ₊ 5y = 330
17x ₊ y = 66 ..eq(2)
Subtracting (1) from (2):
13x=39
x=3
So the number of dimes is x=3; the number of quarters is 3x=9; and since the total number of coins is 27, the number of nickels is 15.
hence the total number of nickels is 15.

Answer:
∠ WUV = 36°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ VWX is an exterior angle of the triangle, thus
8x - 18 = 2x + 8 + 3x + 16
8x - 18 = 5x + 24 ( subtract 5x from both sides )
3x - 18 = 24 ( add 18 to both sides )
3x = 42 ( divide both sides by 3 )
x = 14
Thus
∠ WUV = 2x + 8 = 2(14) + 8 = 28 + 8 = 36°
