Equation 1 is 2W - 6 = L
equation 2 is 140= W * L
L=10
W=8
Answer:
Scale factor = 2, x = 3 cm
Step-by-step explanation:
The scale factor is 2 because you can see that in the second figure you multiply the sides from the first one by 2.
Using the scale factor 2, you can multiply 1.5 * 2 = 3 for x.
I would assume it is 1/120th of a gallon
5(3x-7)=20
15x-35=20
15x= 55
x= 55/15
x= 11/3
Plug this x value in.
6(11/3)-8
66/3 -8
22-8
14
Final answer: 14
Answer:
The hidden variable is age.
Step-by-step explanation:

The children with larger shoes are most probably older so they would have done more years of studying than the younger ones.
The hidden variable is the age of the child.
