11,15,19,23
an = 11 + 4(n-1)
an = 11 + 4n - 4
an = 4n + 7
When they leave home, odometer reads 12,544.....when they arrive in Winterton, the odometer reads 12,671.....this means they have already driven (12,671 - 12,544) = 127 miles.....and now they have 48 more miles to go......so the trip to Sandy Shores from Summerville is (127 + 48) = 175 miles
z=-3
Step-by-step explanation:
we can use formula

we can compare
we get
a=x
b=2
now, we can plug that in formula
and we get

now, we can simplify it
...........Answer
3/4 w = 9
multiply by 4/3 on both sides
4/3 x 3/4 w = 9 x 4/3
w = 9 x 4/3
Simplify that
w = 3 x 4
w = 12
So your final answer is
