Answer: 25 nickels
Step-by-step explanation:
EQUATIONS:
quantity: n + d = 63
value: 5n + 10d = 505
-------------------------
Divide thru the 2nd equation by 5 to get:
n + 2d = 101
----------------
Subtract that from the 1st equation:
-d = -38
d = 38 (# of dimes)
---------------
Substitute that into n+d=63 to solve for "n":
n + 38 = 63
n = 25 (# of nickels)
The simplest form work be in a divide sign such as 2/3
Answer:
y= -3.6
Step-by-step explanation:
-9.5(1.4)-2.5y=-4.3
-13.3-2.5y=-4.3
-9=2.5y
y=-3.6
