Answer:
Therefore the inequality that represents her practice in four weeks is:
Step-by-step explanation:
Mary practiced the piano for two or more each week, in other words the number of hours practiced in a week must be equal or greater than 2. A math expression that can represent this situation can be seen below:
The problem wants us to write an inequality to state how many hours she practiced in four weeks. In order to do this, we need to multiply the number of hours she practiced in a week, given by the last expression, by four. We have:
Therefore the inequality that represents her practice in four weeks is:
4p+20pq+-20qr+-4r
4(p+5pq+-5qr+-1r)
4(p+5pq+-5qr+-1r
