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: No solution
Step-by-step explanation:
I think for number 3, it is the third option.
<span>The total number (n) = 28. This includes the number of cats (c) and the number of dogs (d), which is three times the number of cats. Therefore n = c + d and 28 = c + 3c. 28 = 4c. C = 28/4. C = 7. Kim trained 7 cats.</span>
