No. For instance, let’s look at 1)
It’s asking you to find what x is when x/10 = 6

So, consider the equation x/10=6
Multiply both sides by 10, and your answer is 60.
Now do this for each one.

X+y=3

Subtract x from both sides

y=-x+3

Substitute

2x--x+3=6
2x+x+3=6
3x+3=6

Subtract 3 from both sides

3x=3

Divide both sides by 3

Sati [7]
So, he runs 1.5 then adds 0.5 every day,
1.5
(1.5+0.5)+1.5=x
(2.0+0.5)+x=z
2.5+0.5+z=y
etc.
Why, they want to know the total distance he runs, so thats why you add x,y,z to the end, and you add 2.0+0.5 because he adds 0.5 every dat Plus the other day's miles jogged

The ratio of the areas of corresponding faces of two cubes is 1:16. what is the ratio of their volumes?
Yakvenalex [24]
The ratio of the areas is the one-to-one measure squared.  In order to find the ratio of their volumes, which is a cubed measure, we have to find the one-to-one and them cube it.  The square root of 1/16 is 1/4.  Now if we cube 1/4 to get the volume, it will be 1/64.
