Mathematics
1 answer:
boyakko [2]3 years ago

In this situation, 0.782 would be rounded to 0.8

how to round a decimal: take the underlined number and look to the number located to the RIGHT of the underlined number, if the number to the right of the underlined number is 4 or less you leave the underlined number as is - but if the number right to underlined number is 5 or greater you round the underlined number up by one

ex. 1.83 [round to the nearest tenth]

answer: 1.80

instead of keeping the 3 [hundredth] you turn it into a 0.

Solve the inequality and graph the solution on the line provided.<br> 3 + 2x &gt; 5
ElenaW [278]

Answer:

x>1

Step-by-step explanation:

In order to do this, we can take the inequality:

3+2x>5

now there are constants on both sides meaning we can combine them like the following:

3+2x>5

-3      -3

------------

2x>2

Now we can simplify

2x/2>2/2

therefore, the answer is x>1

In order to graph this on a line you would need to put in a circle which is not filled in because x isn't <u>equal to and greater than</u> 1 so we put in a blank circle and since x is always going to be greater than 1, we would put a line that keeps going on.

You would put this line to the right of 1

o----------->

1 2 3 4 5 6

that is how the line would look like
