Just take the x and do what the word problem says. Number one would be 15+X
Two would be 70-y and so on
AD = AB
AD = 2r+8
AB = 5r-13
we need to find the value of r to find the total length
so 2r+8 = 5r-13
subtract 2r from each side:
8 = 3r -13
add 13 to each side:
21 = 3r
divide both sides by 3
r = 21 / 3 = 7
r=7
now we know r, so replace r with 7 in the equation for AD
AD = 2r+8 = 2(7) +8 = 14 +8 = 22
the answer is D. 22

Answer:
-130 °C
Step-by-step explanation:
The change is found by subtracting the start temperature from the finish temperature. It is ....
-60 °C - 70 °C = -130 °C
Cheapo air : c = 0.15m + 55.75...for 1628 miles
c = 0.15(1628) + 55.75
c = 244.20 + 55.75
C = 299.95
discount air : c = 0.10m + 175.55....for 1628 miles
c = 0.10(1628) + 175.55
c = 162.80 + 175.55
c = 338.35
cheapo air has the cheapest option...and u save (338.35 - 299.95) =
38.40.
2 x 15 = 30, 9 x 22 = 198, 198 + 30 = 228.
So the answer is A 2 children, 9 adults.
