X+(3x+2)+(1)/(2)x=29
Vladimir79 [104]

Answer:

\boxed{x=6}

Step-by-step explanation:

x+3x+2+0.5x=29

\sf Combine \ like \ terms.

4.5x+2=29

\sf Subtract \ 2 \ from \ both \ sides.

4.5x+2-2=29-2

4.5x=27

\sf Divide \ both \ sides \ by \ 4.5.

\displaystyle \frac{4.5x}{4.5} =\frac{27}{4.5}

x=6

Heba ate \dfrac{1}{12} 12 1 ​ start fraction, 1, divided by, 12, end fraction of a box of cereal. Now the box is \dfrac{3}{4} 4
GrogVix [38]

9514 1404 393

Answer:

  5/6

Step-by-step explanation:

If q is the quantity of cereal in the box before Heba ate some, the problem tells us ...

  q - 1/12 = 3/4

  q = 3/4 + 1/12 = 9/12 + 1/12 = 10/12

  q = 5/6

There was 5/6 of a box before Heba ate.

Help! I will give brainliest, amazing rating, and thanks for answer!
prisoha [69]

First, let’s begin with part A of the question. To find the mean, we must find the average of Rolinda’s test scores by adding them all together and then dividing the sum by 5 (the number of test scores). This is shown below:

(85 + 85 + 60 + 62 + 59) / 5

351/5

70.2

Therefore, the mean of Rolinda’s test scores is 70.2.

Next, we should find the median, or the middle number of the sequence after we order the numbers from smallest to largest. This is shown below:

59, 60, 62, 85, 85

Since 62 is the middlemost number in the list, the median is 62.

Finally, we must find the mode, or the most common number in the list. Since 85 is the only number that occurs more than once, we know that the mode is 85.

Next, we move on to Part B. The measure that supports Rolinda’s claim that she is doing well in her Spanish class is the mode, because it is the highest measure out of the three.

The answer to Part C is as follows: This is misleading because the mode is not an accurate representation of all of Rolinda’s test scores and the range that they cover, it only represents Rolinda’s highest score, which she happened to score twice.

Hope this helps!

The circle P has a center at (0, 0) and a point on the circle at (0, 4). If it is dilated by a factor of 4, what is the distance
galina1969 [7]

Answer:

A. 32

Step-by-step explanation:

If the center is (0, 0) and a point is (0, 4) then the distance from the center to that point is 4 units. That distance is the radius. If you are dilating by a factor of 4, multiply the radius by 4 and you get 16. The new radius is 16 and the diameter= radius*2.

16*2=32
