A kilogram %30 chocolate,
b kilogram %50 chocolate,
a+b = 100 kilogram chocolate,
48.(a+b) = 30.a + 50.b
48a + 48b = 30a + 50b
18a = 2b
b = 9a
a+b = a + 9a = 10a = 100 kg
a = 10 kg
b = 9.a = 90 kg
You should use,
10 kg %30 chocolate,
90 kg %50 chocolate
Step-by-step explanation:
6b < 42 or 4b + 12 > 8
6b < 42
= 6b/6 < 42/6
= b < 7
4b + 12 > 8
=4b - 12 + 12 < -12+8
= 4b > - 12 + 8
= 4b > -4
= 4b/4 = -4/4
b > -1
so
7 > b > -1
