Answer:
<u>8</u><u>t</u><u>h</u><u> </u><u>term</u><u> </u><u>is</u><u> </u><u>-</u><u>1</u><u>5</u><u>3</u><u>0</u><u>9</u>
Step-by-step explanation:
r is the common difference, r = -21/7 = -3
(2y + x) + (2y + x) = (-2y + x) + (2x - 15)
2y + x + 2y + x = -2y + x + 2x - 15
4y + 2x = -2y + 3x - 15
+2y + 2y
6y + 2x = 3x - 15
-2x -2x
6y = x - 15
+15 +15
15 + 6y = x
Mean basically means average/ all the numbers added together divided by the amount of numbers given to us
So all the numbers added up will equal to 51 (-5+-3+-1+6+6+9+9+10+10+10) now divide that by the number of of numbers me given to us which is 10 so
51/10= 5.1
Mean=5.1
20% is 1/5 more so it is 1 1/5 times the size of the smaller one. 1 1/5 is 1.2 as a decimal (also 120% divided by 100).
Let's take the smaller bottle to be y.
x=1.2y
x=1.2*5.4=6.48 ounces.
It is 160000 because 8*2 is 16 just add 0000 after the 16
