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)
Answer:ok
Step-by-step explanation:4/7
Answer: 36
Step-by-step explanation:
5(2)+3(-3)-20+3(2)-15(-3)+4
10-9-20+6+45+4
-19+55
36
The solution is (-2,4) she right both have the same solution because if you solve both of them you will get (-2,4)
X equal 5/3 set it equal to zero and slove
