For the first one on top, you would first add 27 plus 60, which is 87. Then, you will divide it by three. So on the outside of the parentheses, you will put down 3. Then, you will subract 87 and 29. You will put 29 and the difference of 87 and 29 inside the parenthese.

For the second one on the bottom, you would read the problem carefully. Notice that in the problem, it says pretzels to chips.That means you would write the cups of pretzels:cups of chips.

Hope this helped.

How does 4 digit addends have a 5 digit sum

denpristay [2]

A 4 digit addends could have a 5 digit sum because of the rule of regrouping.
Regrouping is a situation where carrying and borrowing is involves. So let’s have an example

8999
<span>+5678
</span>14677

so in this example, we added 8999 to 5678.
9+8 = 17, so we bring down 7 and carry 1
9 + 7 = 16 + 1 = 17 , so again we bring down 7 carry 1
9 + 6 = 15 + 1 = 16, bring down 6 carry 1
8+5 = 13 + 1 =14, since this is our last number, bring down 14..
=> 14, 677

Find a + b + c + d.

Flura [38]

Answer:

a + b + c + d = 230

Step-by-step explanation:

So first, I am going to write down everything that I can find out from the picture.

a + b = 115

c + d + (180 - a) + (180 - b) = 360

Now, I can use a + b = 115 to simplify c + d + (180 - a) + (180 - b) = 360.

c + d + (360 - (a + b)) = 360

c + d + (360 - 115) = 360

c + d +245 = 360

c + d = 115

Now I know that:

a + b = 115

c + d = 115

Now I can find a + b + c + d

a + b + c + d = (a + b) + (c + d) = 115 + 115 = 230

a + b + c + d = 230

Determine if the following pairs of lines are parallel, perpendicular, or neither (HINT: Look at slopes).

GarryVolchara [31]

Answer:

Neither

Step-by-step explanation:

The slopes are not opposite and they are not equal either

line up 2x+3y=42 and -3x +2y=16

2x+3y=42=-3x+2y=16

get each term on one side and isolate.

If this is not possible, you have your answer. Another way to do this is graphing it and seeing if the two lines intersect, and if they do, if they make a right angle

valkas [14]

The question is incomplete! Complete question along with answer and step by step explanation is provided below.

Question:

A music teacher asked 23 students in the band how many hours they practiced playing their instrument each week. The results are shown in the dot plot. Which statement best describes the data?

a. The data are skewed left, so most student's practice times are more than the mean practice time.

b. The data are skewed left, so most student's practice times are less than the mean practice time.

c. The data are skewed right, so most student's practice times are less than the mean practice time.

d. The data are skewed right, so most student's practice times are more than the mean practice time.

Answer:

The correct option is a.

The data are skewed left, so most student's practice times are more than the mean practice time.

Step-by-step explanation:

Refer to the attached box plot which shows number of hours the students spent on practice for playing their instrument each week.

When the data distribution is not symmetric around the mean then it is either skewed to right or skewed to left.

The given box plot is skewed to the left since the tail of the distribution on the left side is longer than the right side or in other words, most of the data is leaning to the right side of the curve.

Due to this, most student's practice times are more than the mean practice time.

A left skewed distribution is also known as negatively skewed distribution.

Therefore, we can conclude that the correct option is a.

a. The data are skewed left, so most student's practice times are more than the mean practice time.
