Answer:
y = 3
x = -4
Step-by-step explanation:
Hopefully the first equation is x + 3y = 5
x = 5 - 3y
Plug in:
-2(5 - 3y) + 2y = 14
-10 + 6y + 2y = 14
8y = 24
y = 3
x = -4
Answer:
4, (31 +48), (31+66)
4, 79, 97
Step-by-step explanation:
4 + (x + 48) + (x + 66) = 180 ( sum of angles in a triangle)
4 + 48 + 66 + x + x = 180
118 + 2x = 180
2x = 180 -118
2x = 62
x = 62/2 = 31
44
i think so at least it should be
Initial investment = $775
Monthly investments = $C
Period of investment = 1 year = 12 months
Total monthly investments = Monthly amount*12 = C*12 = 12C
Total investment after 12 months = Initial investment + Total monthly investments = 775 + 12C
