-4(3-5x)≥-6x+9
Use distributive property for the left side:
-4(3-5x)=-12+20x
Now solve for x.

When solving this inequality, the first step that we would want to consider to first do would be the fact of first doing what would be in 'parenthesis'. By doing this, we would be following the step of (pemdas). (p) = parenthesis. And then, we would then do exponents, and therefore finish off with solving the problem.

Which measurements are equal to 671 decimeters? Check all that apply.

iren [92.7K]

Answer:

Answer:

Option A , D and E are correct.

67100 millimeters, 6.71 decameters and 6,710 centimeters measurements are equal to 671 decimeters

Step-by-step explanation:

Use conversion:

1 millimeters = 0.01 decimeter

1 kilometer = 10000 decimeter

1 hectometers = 1000 decimeter.

1 decameter = 100 decimeters

1 centimeters = 0.1 decimeter

As per the statement:

We have to find which measurements are equal to 671 decimeters.

67100 millimeters

Using conversion:

1 millimeters = 0.01 decimeter

then;

67100 millimeters = 671 decimeter.

0.671 kilometers

Using conversion:

1 kilometer = 10000 decimeter

then;

0.671 kilometers = 6710 decimeter.

67.1 hectometers

1 hectometers = 1000 decimeter.

then;

67.1 hectometers = 67100 decimeters.

6.71 decameters

1 decameter = 100 decimeters

then;

6.71 decameters = 671 decimeters

6,710 centimeters

1 centimeters = 0.1 decimeter

then;

6710 centimeters = 671 decimeters.

0.671 kilometers = 6710 decimeter.

67.1 hectometers

1 hectometers = 1000 decimeter.

then;

67.1 hectometers = 67100 decimeters.

6.71 decameters

1 decameter = 100 decimeters

then;

6.71 decameters = 671 decimeters

6,710 centimeters

1 centimeters = 0.1 decimeter

then;

6710 centimeters = 671 decimeters.
