DaniilM [7]

Answer:

The median is 72

Step-by-step explanation:

The median is the middle of a sorted list of numbers. If there is an odd number of values, the median is the value at the middle. Otherwise, it is the mean between the two middle values.

In this question:

Scores: 86, 67, 62, 82, 64 and 77

Sorted: 62, 64, 67, 77, 82, 86

Middle elements: 67 and 77

Median: (67 + 77)/2 = 72

How long is the shorter side of a rectangle when one side is 2 times longer then the other and the area is 15?

iragen [17]

"Two times longer" is taken to mean "two times as long".

The rectangle can be divided into two squares of area 7.5, so the short side is

... √7.5 ≈ 2.739

Maria solved the equation. 4 (3 x minus 8) minus 4 = 24. 12 x minus 32 minus 4 = 24. 12 x minus 36 = 24. 12 x = 60. x = 5. What

Mrac [35]

Answer:

1. Distributive property.

2. Combining like terms.

3. Addition property of equality.

4. Division property of equality.

Step-by-step explanation:

- The Distributive property states that:

$a(b+c)=ab+ac\\\\a(b-c)=ab-ab$

- The Addition property of equality states that:

$If\ a=b\ then\ a+c=b+c$

- The Subtraction property of equality states that:

$If\ a=b\ then\ a-c=b-c$

- The Multiplication property of equality states that:

$If\ a=b\ then\ a*c=b*c$

- The Division property of equality states that:

$If\ a=b\ then\ \frac{a}{c}=\frac{b}{c}$

Given the following equation:

$4(3x-8)-4=24$

We can identify that the methods Maria used to solve it and the order, are:

1. Distributive property:

$(4)(3x)-(4)(8)-4=24\\\\12x-32-4=24$

2. Combining (or adding) like terms:

$12x-36=24$

3. Addition property of equality, because she added 36 to both sides of the equation:

$12x-36+36=24+36\\\\12x=60$

4. Division property of equality, because she divided both sides of the equation by 12:

$\frac{12x}{12}=\frac{60}{12}\\\\x=5$
