<p>PLEASE HELP ME WITH THESE QUESTIONS!!!!!!!!!!!</p>

<ol>
<li><p>Jamie can walk 14 miles in 4 hours. At this rate, how many miles can Jamie walk in 3 hours?</p></li>
<li><p>90n + 23p + 4523 </p></li>
</ol>

<p>If n and p are positive integers in the equation above, what is one possible value of n+ p?</p>

<ol>
<li><p>At a certain hospital, 89 children were born in the month of June. If more children were born on the fifteenth of June than on any other day in June, what is least number of children that could have been born on the fifteenth of June?</p></li>
<li><p>In the xy plane, line L has equation y= 1/4x + 3, and line M has equation y= 1/2x + b. If the lines intersect at the point with coordinates (t, 11/2), what is the value of b?</p></li>
<li><p>In a group of 212 people, there were 37 more males than females. How many males in the group?</p></li>
</ol>

<ol>
<li><p>10.5 miles
14mi / 4h = 3.5 miles per hour
3.5 mph * 3h = 10.5 miles</p></li>
<li><p>51
Is this a mistype? 90n + 23p = 4523 was probably the actual question. If so, the most obvious answer is p= 1 and n= 50, so 51.</p></li>
<li><p>4
There are 30 days in June. To find the least number, we want the most number of children on the other days.
1 child *29 days=29… too small
2 children *29 days=58… still too small
3 children *29 days=87… seems pretty close to 89, but that will leave 2 children to be born on the 15th, which is too small. But what 3 children were born on 28 days, and 1 on the last day to equal 85 children? Then we will have 4 children on the 15th.</p></li>
<li><p>0.5 or 1/2
11/2 = 1/4 x+3
x=10</p></li>
</ol>

<p>11/2 = 1/2*10 + b
b=0.5 or 1/2</p>

<ol>
<li>Another mistype.</li>
</ol>

<p>212-37 = 175
175/2 = 87.5
87.5 + 37 = 124.5 males</p>
