Sure thing, honey. The algebraic expression for m minutes of long distance calls in 1 month would be 0.10m + 5. Grant pays 10 cents per minute, so that's 0.10m, and then he's got that flat rate of 5 bucks per month. So you add those two together and you've got yourself an expression. Hope that clears things up for ya!
To convert 4 and a quarter hours to minutes, you first convert 4 hours to minutes by multiplying by 60 (since there are 60 minutes in an hour), which equals 240 minutes. Then, you add the additional 15 minutes from the quarter hour. Therefore, 4 and a quarter hours is equal to 240 + 15 = 255 minutes.
The duration from 7 AM to 3:30 PM is 8 hours and 30 minutes. To break it down, from 7 AM to 3 PM is 8 hours, and then adding the additional 30 minutes brings the total to 8 hours and 30 minutes.
From 8:30 AM to 4:15 PM, there are 7 hours and 45 minutes. This can be calculated by counting the hours from 8:30 AM to 4:00 PM (which is 7 hours) and then adding the additional 15 minutes.
First, obviously, you have to stare at the five terms that you're given, and tryto figure out what's going on here ... what rule is generating those terms. Then,once you've spotted the rule, you have to write an algebraic expression for it.I stared at this thing for a few minutes, and finally understood what's going on:The sequence is just a list of the squares of the counting numbers, but for eacheven counting number, the term of the sequence is negative.So the algebraic expression for the rule needs two parts: One part that producesthe square of 'n', and another part that makes the term negative if 'n' is an evennumber.Can you do that now ?What I came up with is:The 'n'th term of the sequence is (-1)(n+1) times n2You see, (-1)(n+1) is just ' 1 ' when 'n' is odd, and ' -1 ' when 'n' is even.
m = 60*n where m is the number of minutes.
x = (8*60) - m
The rule for cooking meat is 44 minutes per kilo, plus an additional 20 minutes. In this case, it's 600 minutes (10 hours !)
Expression I think

The expression would be: (Number of babies born per minute) x M minutes = Total babies born in M minutes.
Boil tortellini for about 7-10 minutes for optimal cooking.
Parboil chicken for about 10-15 minutes before cooking it.
To calculate the cooking time for a 20-pound turkey at 325 degrees with a cooking time of 20 minutes per pound, you would multiply the weight of the turkey by the cooking time per pound. In this case, 20 pounds multiplied by 20 minutes per pound equals 400 minutes. To convert this to hours, you would divide by 60, resulting in approximately 6.67 hours of cooking time for the turkey at 325 degrees.
The recommended cooking time for barley is typically around 30-40 minutes.
Microwave artichokes for 5-7 minutes for optimal cooking.
Microwave sausage for 2-3 minutes for optimal cooking.
