[tex]x=200[/tex]

Explanation:

Okay so we can start by substituting in [tex]y[/tex] as we know what it is already:

[tex](\frac{1}{5} )x-(\frac{2}{3} )(15)=30[/tex]

Now at this stage we could use a calculator to figure out what [tex]\frac{2}{3}[/tex] of [tex]15[/tex] are though a bit of mental math is as easy:

[tex](\frac{15}{3} )[/tex] · [tex]2=[/tex] [tex]5[/tex] · [tex]2[/tex]

okay so now we have:

[tex](\frac{1}{5} )x-10=30[/tex] add 10 to both sides to get rid of the [tex]-10[/tex]

[tex](\frac{1}{5})x=40[/tex] let's get rid of that fraction by multiplying by [tex]5[/tex]

and there's the solution for x

We can check we got this right by substituting it back into the original equation with the known y:

[tex](\frac{1}{5} )(200)-(\frac{2}{3})(15)=30[/tex]

now, and we already know what out of is so :

that means

which is ✓

Therefore we know our solution is right.

the water?
a. What number represents the position of the fish
relative to the surface of the water?
b. How does the absolute value of the number
you wrote show that the distances are the
same? Explain.

Answers

Answer:

I believe a is -14

Step-by-step explanation:

its -14 because if it is in the exact same spot below water, think of the water as point 0. the bird is 14 and the fish is -14. Hope this helped
