Answer:
<h2>3. If a ≥ b, then a + c ≥ b + c
</h2><h2>4. If c > d, then a– c < a – d</h2>
Step-by-step explanation:
The inequalities 3 and 4 are the right ones, because they are actually properties of inequalities.
The other choices aren't correct. For example, the first choice: a – b < a + b, it's not true, because you must apply the same change at each side of the inequality, otherwise you'll ruin the expression.
Choices 2 and 5 are also false.
Therefore, the right answers are 3 and 4.
Answer:
Paul will have no more than $ 450 in next 8 weeks.
Step-by-step explanation:
From the information given on statement, we know that Paul saves all of his earnings weekly. Then, the money save is equal to the sum of initial amount (
), measured in monetary units, and week earning (
), measured in monetary units, multiplied by a number of weeks (
), dimensionless:
(1)
Now we clear the number of weeks within the formula:
If we know that 
, 
and 
, then the number of weeks is:
Paul will have no more than $ 450 in next 8 weeks.
