Answer:
B and C
Step-by-step explanation:
Answer:
3a. 8t + 12c = 72
3b. t + c = 7
Step-by-step explanation:
number of tapes is t
number of Cds is c
so 8t + 12c = 72
and t + c = 7
so t = 7 - c
replace t = 7 - c in to the first equation
8(7 - c) + 12c = 72
56 - 8c + 12c = 72
4c = 72 - 56 = 16
c = 4
if c = 4, then t = 7 - c = 7 - 4 = 3
Answer:
5
Step-by-step explanation: 5/13 8 48
graph the function, center the center of the circle find the difference between the center and the circle
center at (-7, 7)
sorry I don't know how to find it mathematically. I'll try to figure out later, if you need an mathematically solution.
