The correct answer is 3380 meters
Explanation:
The initial elevation of the hike can be represented as -20 meters, this is because the initial elevation is below the sea level, and in terms of elevation the sea level is considered to be 0. Now, using this number the final elevation can be calculated by adding the two numbers:
-20 + 3400 = 3380
This implies the final elevation has 3380 meters
You can also get this same result by considering there are 20 meters from the initial elevation to the sea level and then 3380 meters from the sea level to the final elevation (3380+20 = 3400).

Step-by-step explanation:
Answer:
Cost of one candy = 80 L.L.
Step-by-step explanation:
Let "x" represent cost of a candy
Cost of 12 candies = 12x
Cost of a chocolate bar = 1,250 L.L.
Total cost = 2,210 L.L.
The following equation represents the scenario given:
1,250 + 12x = 2,210
Solve for x (cost of a candy)
1,250 + 12x - 1,250 = 2,210 - 1,250 (subtraction property of equality)
12x = 960
Divide both sides by 12
12x/12 = 960/12 (division property of equality)
x = 80
Cost of one candy = x = 80 L.L.
Jenna has $43 and Heidi has $17.
Step-by-step explanation:
Total amount = $60
Let,
Amount of Jenna = x
Amount of Heidi = y
According to given statement;
x+y=60 Eqn 1
x=2y+9 Eqn 2
Putting value of Eqn 2 in Eqn 1;
Dividing both sides by 3,
Putting y=17 in Eqn 2
Jenna has $43 and Heidi has $17.
