Answer:
x = 6
Step-by-step explanation:
An inverse variation is
xy = k where k is the constant of variation
8*9 = k
72 = k
xy = k
Let y = 12
x*12 = 72
Divide each side by 12
12x/12 =72/12
x = 6

Step-by-step explanation:
Answer:
The Large Box Weighs 18 kg, and the small box weighs 6.5 kg
Step-by-step explanation:
Let a= the weight in kg of a large box
Let b= the weight in kg of a small box
Multiply both sides of (1) by 4 and subtract (2) from (1)
1. 20a+8b=412
2. -3a-8b= -106
17a=306
a=18
and
5*8+2b=103
90+2b=103
2b=13
b=6.5
