Answer:
$46.27
Step-by-step explanation:
we know that
The average cost of 5 gallons of regular unleaded gasoline in the United States was $14.46
using proportion
Find out the average cost for 16 gallons of gas
Let
x ----> the average cost for 16 gallons of gas
when a rotation of 180 ° happens, it switches the (x,y) coordinates from (x,y) to (-x,-y) .. that's alll... soo for M then, of (3,4) it switches to M ' = ( -3, -4) see?
Sn = n/2[2a + (n-1)d]
n=11
a=2
d=3
Sn= 11/2[2(2) + (11-1)3]
Sn= 11/2(34)
Sn = 11x17
=187.
me either
=5/21L+ -5/84
=-(5/7) (-(1L/3-3/4)+1/3/4)
=(-5/7)(-(1L/3-3/4))+(-5/7)(1/3/4)
=5/21L= -15/28+ -5/84
=5/21L=+ -25/42
