Planet X is 8 1/5 light-years away from Earth. Planet Y is 2 3/5 light-years away from Earth.
Law Incorporation [45]

Based on the distance of Planet X from Earth and the distance of Planet Y, Planet X is 5 ³/₅ light-years farther away.

<h3>How much farther is Planet X from Earth?</h3>

To find how out how much farther planet X is from Planet Earth than Planet Y, subtract the distances:

Solving gives:

= 8 ¹/₅ - 2 ³/₅

= 41/5 - 13 / 5

= 28/5

= 5 ³/₅ light-years

How many liters each of a 35% acid solution in a 80% acid solution must be used to produce 60 L of a 65% acid solution?
STALIN [3.7K]

Let <em>x</em> and <em>y</em> be the required amounts of the 35% and 60% acid solutions, respectively.

<em>x</em> liters of 35% acid solution contains 0.35<em>x</em> L of acid.

<em>y</em> liters of 80% acid solution contains 0.80<em>y</em> L of acid.

Together, a combined (<em>x</em> + <em>y</em>) L of mixed solutions contains (0.35<em>x</em> + 0.80<em>y</em>) L of acid.

You want to end up with 60 L of 65% acid solution, which means

<em>x</em> + <em>y</em> = 60

0.35<em>x</em> + 0.80<em>y</em> = 0.65 × 60 = 39

Solve for <em>x</em> and <em>y</em> :

<em>y</em> = 60 - <em>x</em>

0.35<em>x</em> + 0.80 (60 - <em>x</em>) = 39

0.35<em>x</em> + 48 - 0.80<em>x</em> = 39

0.45<em>x</em> = 9

<em>x</em> = 20

<em>y</em> = 40
