Stella [2.4K]3 years ago
7 0

First:

Subtract 5 on each side of the equals sign to cancel it out. You should get 13x=144.

Next:

Divide 13 from each side of the equals sign to get x by itself.

Answer:

X=11.0769230769. You may need to round it up to 11.08 or 11.1 depending on how your teacher normally has you answer

The table below shows the amount of lemon juice and sugar needed to make three different-sized batches of lemonade using the sam
Amiraneli [1.4K]

Answer:

The equation is:

        j/g=5/2

Or, what is equivalent:

        j=5g/2

Explanation:

This is the<em> table</em> that <em>shows the amount of lemon juice and sugar needed to make three different-sized batches of lemonade using the same recipe</em>:

                        Lemon juice (mL)       Sugar (g)

Batch A               500                            200

Batch B                750                            300

Batch C              1500                            600

You need to write an <em>equation to describe the relationship between j, the amount of lemon juice in mL and s, the amount of sugar in g</em>.

Calculate some ratios, to determine the kind of relation between the amount of juice and the amount of sugar in the recipe.

  • Batch A: lemon juice / sugar = 500 / 200 = 5/2

  • Batch B: lemon juice / sugar = 750/300 = 5/2

  • Batch C:  lemon juice / sugar = 1500/600 = 5/2

Hence, the amount of juice, j, and the amound of sugar, s, are proportional and the constant of proportionality is 5/2. From this, the equation is:

        j/g=5/2

Or, what is equivalent (solving for j):

        j=5g/2
