Answer:
The answer is in the attachment.
Step-by-step explanation:
Look at the picture.
Multiply the first equality by 3/2 and you get the second
There are thus an infinite number of solutions : x can be any number and y=2-3x/4
1 times 10 is 10. 10 times 10 is 100. So for those 3 models, the base is 10. All grids relate to the base 10 number system, because from left to right, the shaded part is getting bigger (increasing) by multiplying by 10. Hope this helps!
