a + 5 = 11

You need to isolate the variable by subtracting from both sides

a + 5 - 5 = 11 - 5a = 6

The Addition/Subtraction Property of Equality states that if you add or subtract the same number to both sides of an equation the two sides still remain equal

Doctor florens needs 25 g of salt for each student to do an experiment she has 1.2 kg of salt on hand she has a total of a 128 s

erik [133]

The first thing I would do is convert that 1.2 kilograms of salt to grams; that would ensure that all the units are the same so we can perform calculations on them.

1.2kg = 1200g

Next, I would find out how many students can do the experiment with 1200g of salt, by finding it how many 25g are in 1200g (by dividing them).

$\frac{1200g}{25g}=48students$

That means we still have 80 students left to provide salt for (128 - 48).
Therefore, he needs an additional 80 amounts of 25g of salt.

Therefore he needs:
$80students*25g = 2000g = 2kg$
