Step-by-step explanation:
Hint x = 1 + x1 + ......... Xn-1
attached below is the detailed solutioN
usually like poles of magnets repel each other and unlike poles of magnets attract each other forming a block
Answer:
Let x = the number of quarters
Let y = the number of nickels
X + y = 62 x = 62 - y
.25x + .05y = 12.50 Multiply both sides of the equation by 100 to get rid of the decimal points.
25x + 5y = 1250
25(62-y) + 5y = 1250
1550 - 25y + 5y = 1250
-20y = -300
y = 15 nickels
x = 62 - y = 62 - 15
x = 47 quarters

Answer: Choice B) -5.2 degrees
=====================
Work Shown:
Add up the given temperatures
-42 + (-17) + 14 + (-4) + 23 = -26
Then divide by 5 since there are 5 values we're given
-26/5 = -5.2
