52.85 ROUNDED AT NEAREST ONE
RoseWind [281]

Answer: 53

52.85 is closer to 53, than it is to 52

The digit after the ones digit is 8, which is 5 or larger, so that tells us to round up from 52 to 53. We drop everything after the ones digit.

-3a + 4 ≥ -16<br><br> Solve, and show your work.
storchak [24]

Answer:

a ≤ 20/3

Step-by-step explanation:

Subtract 4 from both sides, obtaining:

-3a ≥ -20.  Dividing both sides by -3, we get a ≤ 20/3.

Note that because this is an inequality, and because we've divided all terms by a negative number, we must change the direction of the inequality symbol from ≥ to ≤.

What is the ordered pair for point b on the graph (-1,4) (4,-1) (5,1) (1,5)
IRINA_888 [86]

Option C: (5,1) is the ordered pair for point B

Explanation:

The graph is plotted with unit scale 1 units for both x and y axis.

We need to determine the ordered pair for point B.

<u>Ordered pair:</u>

Since, the graph is plotted with unit scale 1, the point B is 5 units away from the point (0,0)

Thus, the x - coordinate for point B is 5.

Also, the point B is 1 unit away from the point (0,0)

Thus, the y - coordinate is 1

The coordinates of point B is (5,1)

Thus, the ordered pair for point B is (5,1)

Hence, Option C is the correct answer.
