4(2x-3) is greater than or equal to 4(x-4)
mylen [45]

Answer:    x ≥ -1

<u>Step-by-step explanation:</u>

4(2x - 3) ≥ 4(x - 4)

8x - 12 ≥ 4x - 16       <em>distributed 4 into 2x - 3</em>

4x - 12 ≥ -16              <em>subtracted 4x from both sides</em>

4x ≥ -4                       <em>added 12 to both sides</em>

 x ≥ -1                        <em>divided both sides by 4</em>

Round each value to the nearest 10 and find an estimate of the expression:
GuDViN [60]
Note: to round to the nearest ten, look to the first place digit. if it is 5 or greater, round up, if 4 and lower, round down

<em>124 rounded to the nearest ten = 120</em>
<em>38 rounded to the nearest ten = 40</em>
<em>71 rounded to the nearest ten = 70</em>
<em>207 rounded to the nearest ten = 210

120 + 40 + 70 + 210 = 120 + 110 + 210 =  230 + 210 = 440

440, or C </em>is your answer

hope this helps

Rita caught 5 fish. The lengths, in inches, of each tish are listed.
Aloiza [94]

Given:

The lengths, in inches, of each fish are listed:

9, 13, 9, 21, 18

To find:

The statement that best represents the meaning of the range for these data.

Solution:

The given data values are:

9, 13, 9, 21, 18

Arrange the data values in ascending order.

9, 9, 13, 18, 21

Here, the maximum value is 21 and the minimum value is 9.

We know that,

\text{Range}=\text{Maximum value}-\text{Minimum value}

\text{Range}=21-9

\text{Range}=12

The range of the data set is 12. Therefore, the difference between the shortest and longest fish is 12 inches.
