Answer:

Step-by-step explanation:

I am very sorry if this doesnt make sense but i tried to give you an example for the first one so you could figure out the 4 and 5.

If y=12 when x=6, determine y when x=18.

Ok if y=12 and x=6 they add up to 18. So X=6 then you are going to have to times 6 by three to get x to equal 18. That means we have to times y by 3 also which equals 36. We can check this by making sure they are congruent or the same. So if the origanal question said y equals 12 and x equals 6. How do you make sure it's the right answer? What do they have in commmon? Well to get 12 you have to multiply 6 by 2 to get 12. And to get 6 you have to divide 12 by 2. So the common number is 2. So for x to equal 18 we have to figure out is the have something in common, so 18 times 3 equals 36 and if 36 divided by 3  we get 18. So the common number is 3.

Explain why one column in a hundredths grid is equal to one column in a tenths grid.
fomenos
In a hundredths grid - square
In a hundredths grid, there are 10 blocks in each column. 10/100 = 10%. So one column is equal to 10%.
In a tenths grid- square
In a tenths grid, there is one block in each column. So 1/10 blocks = 10%. 
10/100 can simplify into 1/10. This is why both grids are equal. They are both equivalent fractions. Both grids have columns that equal 10%.

Someone please help me with this question!
Shtirlitz [24]
I'm assuming you're looking for the measure of angle y.  Rule is that angle y will be equal to 1/2 of its intercepted arc.  That arc measures 360-160-60 which is 140.  Half of 140 is 70.  So the first choice above is the one you want.
