Answer:
Step-by-step explanation:
1/6+1/4=5/12
5/12 of the job is done in 1 hour
so
5/12+5/12= 10/12
so 10/12 of the job is done in 2 hours
and then simplify 5/6 so then add 1/6
so it is done in 2 hours and 24 minutes
The difference in unit prices of Jalen's and Tia's juice packs is $0.15
<em><u>Solution:</u></em>
Given that,
<em><u>Jalen bought 24 juice packs for $7.20</u></em>
Unit price means price per juice pack
Unit price is found by dividing 7.20 by 24
Thus unit price of Jalen is $ 0.3
<em><u>Tia bought six juice packs for $2.70</u></em>
Unit price is found by dividing 2.70 by 6
Thus cost per pack of Tia is $ 0.45
<em><u>Difference in the unit prices of Jalen and Tia juice pack</u></em>
Difference = $ 0.45 - $ 0.3
Difference = $ 0.15
Thus the difference in unit prices of Jalen's and Tia's juice packs is $0.15

Answer:
Step-by-step explanation:
First your going to plug in what p and q are into the equation so 3(2)^5+10(-3)^2 over 7(2)+1.
Your going to first do (2)^5 and (-3)^2 so it’s going to be 3(32)+10(9) over (multiply the 7(2) first) 14+1.
3(32)+10(9) over 14+1 now multiply 3(32) and 10(9) you should get (96)+(90) over 15.
add 96+90 to get 186 over 15.
then divide how many times 15 can go into 186 you should get 12 6/15 and divide 6/15 by 3 to get your final answer 12 2/5.
I hope this helps!
Answer:
120 ≤ 20c + 40s
Step-by-step explanation:
(Assuming her name is Kylie, who is giving 40 minute science sessions and 20 minute Chinese sessions.)
The unit for time will be minutes.
Write an equation for time needed for science sessions
40s = t
Write an equation for time needed for Chinese sessions
20c = t
Combine the two equations for the total time.
20c + 40s = total time
She does not want the total time to be more than two hours.
Convert two hours to minutes. There are 60 minutes in an hour.
2h * 60mins = 120 mins
Therefore t ≤ 120. Include this into the equation.
120 ≤ 20c + 40s
