5 and 10.
5 × 10 = 50
5 + 10 = 15
X + y = 12
x - y = 4
(12 - 4) : 2 = 4
4 + 4 = 8
x = 8
y = 4
-----------------------
8 + 4 = 12
8 - 4 = 4
Answer:
6.75
Step-by-step explanation:
2+10+1+8+12+6+23+5+8+4+4+3+2.59+5.11+5.18+9.07 = 107.95
now we count how much numbers you added up which equals 16 and divide it with 107.95
107.95/16 = 6.746875
now you cant pay half a penny or such and such
so your round it off at 6.746 to 6.75
and there you have it
17 because you multiply the 17 and x
