Answer:
1)
[tex]n \leqslant 4[/tex]
Step-by-step explanation:
7n÷7=n
28÷7=4
This is because with inequalities, our job is to isolate the variable (n for this one). We can do so be reversing the math applied to the variable. In this problem, 7n means you would multiply n by 7. To find out what n means, we want to reverse the multiplication on both sides of the inequality. Since the opposite of multiplying is dividing, you want to divide each side by 7. 7n divided by 7 would cancel out 7, leaving you with just n. This is called isolating the variable. For the last step, you divide 28 by 7, which is 4. When you combine these 2 parts, your finished inequality should be
[tex]n \leqslant 4[/tex]
