Answer: The Subtraction Property of Equality
In the problem that Jax solved he subtract 5 from both sides of the equation. This is an example of the subtraction property of equality.
The property states that if you subtract the same amount from both sides of an equation the equation remains the same.
-3x+4=-17
subtract -4 from both sides
divide -3 from both sides
the answer is 7
Basically we want to know how many times 5/8 goes into 5 1/4.
5 1/4 ÷ 5/8 = 21/4 ÷ 5/8 = 21/4 × 8/5 = 42/5 = 8.4 bags
Since we cannot have a fraction of a bag, he can fill 8 bags completely.
answer: 8 bags
Answer:
Step-by-step explanation:
The idea here is to be able to write and then solve the equation needed for this. In words, this is what you are looking to solve: "The active ingredinet is 45% of the mass of the pill". Putting those words into an equation:
active ingredient = .45 (mass of pill). Since our active ingredient is 35 mg:
325 = .45m and divide by .45:
m = 722.2 mg
