Answer:
Step-by-step explanation:
i would say is that every 20 mins its 80 that means every hour its 240 so just multiply it by 8 idk if its right but thats what i would do
For this question you will have to find your own set of data for your area, just go to weather.com or a similar site and make a set of temperatures for the next 7 days in your area. The mean can be found by adding all temperatures, then dividing their sum by the number of objects being added.
For example, if my set of temperatures were {75, 90, 83, 77, 91, 88, 80}, I would find the mean with the equation (75 + 90 + 83 + 77 + 91 + 88 + 80)/7, or 83.4
59 just add both the answers
P=number of pens
h=number of highlighters
p+h=8
1.09h+0.69p=752
p+h=8
minus h from both sides
p=8-h
sub that for p
1.09h+0.69(8-h)=7.52
1.09h+5.52-0.69h=7.52
0.4h+5.52=7.52
minus 5.52 from both sides
0.4h=2
divide both sides by 0.4
h=5
sub back
h=8-p
5=8-p
minus 8 frm both sides
-3=-p
mltiply both sides by -1
3=p
3 pens you bought
12.99+2.50=15.49
20.00-15.49= 14.51
X=CD
Y=Birthday card
Z=total
L=money left
X+Y=Z
20-z=L
(I hope this helps at least a little?)
