Can anyone help, please? -1.3 ≥ 2.9 -0.6r Graph the solution

1 answer:

3 0

Solving this kind of problem is easier if you take steps to make the coefficient of the unknown a positive one. Adding 0.6r to both sides makes the coeff. of r a positive one: 0.6r greater than or equal to 2.9+1.3.

0.6r then is equal to or greater than 4.2. Divide both sides by 0.6 to isolate r:

r greater than or equal to 7.

Let r be represented by the horizontal number line. Darken r = 7 and also darken the r axis to the right of r=7.

Moses got into an elevator. He went down 5 floors, up 6 floors and down 7 floors. He was then on the Second floor. On what floor

skelet666 [1.2K]

Answer:

Moses got into the elevator at the 8th floor.

Step-by-step explanation:

Let's call the floor which Moses started at x. Going down decreases the floor number and going up increases the floor number. We then form the equation $x-5+6-7=2$ which is the same as $x-8=0$ which means $x=8$ . Moses got in at the 8th floor.
