It travels 2144 in 8 hours.

Therefore, if you want to find out how many miles it travels in one hour, divide 2144 by 8.

A hike starts at an elevation 20 meters below sea level and ends at a point 3400 meters higher than the starting point. What wou
QveST [7]

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).

Solve the system of equations using subtraction. Equation 1: 3x-2y= -2 Equation 2: 3x + y = 10 The solution is (? ,?) HURRY PLEA
Art [367]

Answer:

the solution is x = 2 and y = 4 OR (2,4)

Step-by-step explanation:

From the question

Equation 1: 3x-2y= -2

Equation 2: 3x + y = 10

Subtract equation 1 from equation 2, that is

3x + y = 10 - (3x -2y = -2)

You get

3x - 3x + y - (-2y) = 10 - (-2)

0 + y + 2y = 10 + 2

3y = 12

Divide both sides by 3

∴ y = 12/3

y = 4

Substitute the value of y into equation 2 to get x

3x + y = 10

3x + 4 = 10

Then,

3x = 10 - 4

3x = 6

Divide both sides by 3

∴ x = 6/3

x = 2

Hence, the solution is x = 2 and y = 4
