Question

In $18-23,$ write and solve an equation or an inequality to solve the problem.
To prepare for a tennis match and have enough time for schoolwork, Priscilla can practice no more than 14 hours. If she practices the same length of time on Monday through Friday, and then spends 4 hours on Saturday, what is the most time she can practice on Wednesday?

uh, right and solve an equation or inequality to solve the problem. To prepare for a tennis match and have enough time for school work, Priscilla can practice no more than 14 hours if you practice is the same length of time on Monday through Friday and then spends four hours on Saturday. What is the most time she can practice on Wednesday? So we know that this is actually a question about inequalities because it says that Priscilla can practice no more than 14 hours so we can set up our equation. And we know that Monday, Tuesday, Wednesday, Thursday and Friday. All five of those days are gonna be the same. She&#x27;s gonna practice the same round on each of those days. So we get five D D stands for days plus four, and we know that she works for hours on Saturday. SATs were getting that for From is going to have to be a less than or equal to 14 and we&#x27;re getting less than or equal to it because it says that pursuing practice no more than 14 hours, so we will further we will further evaluate this. Yet five D is less than or equal to 10. Our last step is going to be to get rid of this coefficient. So we get D is less than or equal to 10 to 5. 04 to 2. 10 over five secret too. So we get that she can practice for at most two hours.

Okay, so the average time spent by females on homework homework each week is 6.8. And I know that this person has spent no more than 6.8 hours. So let&#x27;s read a couple of numbers. 6.8, 6.76 point nine. Okay, they spend no more than 6.8 hours on homework. Could they spend 6.8 hours? They spent no more than so. Maybe they spent at the most 6 20 hours. Could they spend 6.7 hours on homework? They spent no more than 6.8 hours so they could spend 6.7 hours. Could they spend 6.9 hours? No. They spent no more than or the greatest 6.8 hours, so they can&#x27;t spend 6.9. So I know my any quote is gonna be equal to 6.8, but less than 6.8 hours on average.

on for this problem, we would first set. Why? To be the nuts that Andy um, ordered her cat. So from the, um, description off the question, we know that there&#x27;s a h dollar fee that is fixed. And for each night will it at on $12. So the equation would be eight. Class 12. Why? Close to 80? It is the amount of money um, she cost she paid. And we will solve this equation. The solution is our answer. So we would first subject eight from both sides. The left side would be eight class on trial, huh? Tells eight plus 12. Why miners age on the right part will be 80 miners. Eight. So it would be a trav y e coasters 72. And then we would divide both sides by Charles. That would be 12 y over child, because to 72 over 12. So why been closed to six? It&#x27;s a solution to this equation. And we know that Andy on board has boarded her cat for six. Nice. This is the answer

Okay, So I know that this person let&#x27;s call that will start them with an I spent at least mawr at least more than one hour more. Then the boys did. So the boys, the male spend an average of 5.4 hours. It&#x27;s one more than that. So I know that inequality is gonna involve a variable. And 5.4 plus one is 6.4. The question is what is at least mean? So could it could they have spent six hours? Well, there has been, at least so more than 6.4 hours. Could they spend exactly 6.4 hours? Yes. State at the minimum spent that much so it&#x27;s gonna be equal. Could they spend 6.5 hours? Yeah, I think it&#x27;s been more than that. So my inequality is gonna be greater than or equal to six point

Okay, So let&#x27;s say that band members at your school are expected to practice at least 20. An average of 20 minutes per day. So your friend who&#x27;s in the bad practices? 15 minutes. The first day, 28 the second day, 30. The third day he didn&#x27;t practice at all. The fourth day 15 the sixth day in 25. The 70. So we want to see how or yeah, we want to see how long guests of practice on the last day of the week toe averaged just 20 minutes a day. So I&#x27;m gonna allow these together, right? And I&#x27;m gonna plus whatever I practice on that last day and says I&#x27;m kind of running through out of room on this page. I&#x27;m gonna add these all together first, and then show you the next step. So So this will give me a total, um, time. I practiced this week, so I have 113 plus next. Now, if I want the average of this, I&#x27;m gonna divide by seven. Because there seven days in the week. And if you look at this role above, I have seven, um, different numbers there. And now that would give you the average I practice each day, and they want not to be greater than or equal to Tony. So now my goal is to get expert itself to do that. My first step, um, is to get rid of my division here and toe under division. I need toe multiply. I do it to one side. I have to go to the other to get rid of those sevens. Then they have 113 plus X is greater than or equal to 20 times spice seven, which is 140. So then I need to subtract my 113. So I, um I just want to show you guys this right here. I wrote a seven, but it should be that X right. So I&#x27;m just gonna fix that. Okay, so I subtract the 1 13 on both sides. Please go away and X is greater than a photo. 1 40 minus 1 13 Just going to give me 27. So I&#x27;m gonna have toe practice for 27 minutes. Thought last day

unless first defying X. That&#x27;s the amount off. As a DEA. Andi, we defined why, as the amount off the opinion. So we will get equation 19 X plus five. Why is less than 49 and we would get five. Why is dust and 49 miners on 19 X and we know acts is larger or equal to zero. So miners 90 x iss either equals to zero or positive in them or inactive number. So we know this is not active, and, um, we won&#x27;t you get the maximum value off. Why? So we need the right part to be as large as possible. So we would get the the part, uh, miners 19 x to be zero. So, um, when it close to zero, the right part would be the largest. So why would be the largest? So we was then self the equation that hiss five. Why, oh, less less than 49. And why is the last 49 over five? So, um, because why is that integer? So we&#x27;ve got Cem largest in future. That is, Let the last thing for 49 over five is NY. So the answer for the problem is no
