Answer:
The answer to your question is: n = 95°
Step-by-step explanation:
The sum of the suplementary angles equals 180°
Then
121 + x = 180
x = 180 - 121
x = 59°
144 + y = 180
y = 180 - 144
y = 36°
The sum of the internal angles in a triangle equals 180°
x + y + z = 180
59 + 36 + z = 180
z = 180 - 59 - 36
z = 85
Finally
n + 85 = 180
n = 180 - 85
n = 95°
4x + 3y= 12
4x + 3*0= 12, x-int= 3
4*0 + 3y= 12, y-int= 4

The answer is: " 340 " . There are 340 nickels in 17 dollars.
<span>___________________________________________________</span>
Explanation:
______________________________________________
There are 20 nickels in one dollar.
Since 1 dollar = $1.00 = 100 cents ; and:
1 nickel = 5 cents
________________________________________________
(5 cents)*x = 100 cents ; solve for "x" ; x = the number of nickels in 1 dollar;
Divide each side of the equation by "5 cents" ;
[(5 cents)*x] / (5 cents) = (100 cents) / (5 cents) ;
to get:
_____________________________________________
x = 20 .
_____________________________________________
There are 20 nickels in one (1) dollar.
20 nickels * 17 dollars = number of nickels in 17 dollars.
___________________________________________________
20 * 17 = 340 nickels in 17 dollars.

The answer is: " 340 " . There are 340 nickels in 17 dollars.
