Answer:

Marcia is 47 inches tall.

Step-by-step explanation:

Let's solve this step by step and try to visualize the situation.

• Carl: 73 inches tall

The second part of the question states that Carl's heigh is twenty-one inches less than two times Marcia's height. Add 73 + 21 to equal 94. Since Carl is 21 inches less that means that Maria is 21 inches more ( so that's why I added instead of subtracting) because we are trying to find Maria's equation.

Let x be Marcia's height

2x = 94

• The question staes that 73 is 21 inches less than two times Marcia's height which means that the equation 2x = 94 applies because 73 + 21 = 94

After simplifying the equation, we can get the answer that Marcia is 47 inches tall.

Answer:

Step-by-step explanation:

Givens

Carl  = 73

Marcia = 2x - 21 = 73

Solution

2x - 21 = 73                           Add 21 to both sides.

2x = 73 + 21                          Combine

2x = 94                                 Divide by 2

2x/2 = 94/2

x = 47

Please help with all of these 5 points per question
liberstina [14]

Answer:

1. C = $100 = .25(m)

2. C = $150

3. 800 = m

Step-by-step explanation:

1. C = $100 (flat fee rate) + .25m

2. c = $100 + .25(200 miles)

                           ↓

            c = $100 + 50

                           ↓

                       c = 150

3. 300 = 100 + .25(m)

  -100      -100                    (subtract on both sides)

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

200 = .25(m)

-------------------   (divide by .25 to get m by itself)

    .25

Therefore being 800 = m

Find the mean, meadian, mode and range for each set of data 6, 9, 2, 4, 3, 6, 5
Helga [31]

Mean: Add up the numbers and divide the sum by the number of values in the set.

6 + 9 + 2 + 4 + 3 + 6 + 5 = 35

35 / 7 = 5

Median: Sort the set from the smallest value to the largest value and select the number in the middle. If the count of the set if even, then select the two middle values and take their mean average.

2, 3, 4, 5, 6, 6, 9

            ^

So, the median average is 5.

Mode: What number appears the most frequently?

The mode of the set is 6 because it appears twice.

Range: Sort the set by ascending order and take the smallest value and subtract that from the largest value in the set.

9 - 2 = 7

The range is 7.
