Answers

Answer:

x=-3

Step-by-step explanation:

-2(-x-3)-4x-1=13

2x+6-4x-1=13

-2x+5=13

-2x=8

x=-4

Answer:

x = -4

Step-by-step explanation:

Expand

2x + 6 - 4x - 1 = 13

Rearrange, by collecting like terms and placing them on either side of the equation.

2x - 4x = 13 + 1 - 6

Simplify

-2x = 8

Divide both sides by -2

-2/-2x = 8/-2

x = -4

This program will calculate the rise in ocean levels over 5, 10, and 50 years, Part of the program has been written for you. The part that has been written will read in a rise in ocean levels (per year) in millimeters. This value is read into a variable of type double named risingLevel. You will be completing the program as follows Output the value in risingLevel. This should be the first line of output. The output should be as follows (assume risingLevel has a value of 2.1) Level: 2.1 The number of millimeters higher than the current level that the ocean's level will be in 5 years (assuming the ocean is rising at the rate of risingLevel per year). This is your second line of output. The output will be as follows Years: 5, Rise: 10.5 The number of millimeters higher than the current level that the ocean's level will be in 10 years (assuming the ocean is rising at the rate of risingLevel per year). This is your third line of output. The output will be as follows (for a risingLevel" of 2.1 Years: 10, Rise: 21 The number of millimeters higher than the current level that the ocean's level will be in 50 years (assuming the ocean is rising at the rate of risingLevel per year). This is your final line of output.The output will be as follows (for a risingLevel" of 2.1) Years: 50, Rise: 105 For each of the above you need to output the number of years and the total rise in ocean levels for those years.
