The distributive property in a given field combines multiplication with addition, that is in a field <span>F<span>, any elements <span><span><span>a<span>,b</span></span> and </span><span>c which satisfy the following rule:</span></span></span></span>

<span>a(b+c<span>)=</span><span>ab</span>+<span>ac</span></span>

<span><span> </span> </span>

<span>The whole numbers are a subset of the field </span><span>R, which is composed of all rational and irrational numbers, hence the whole numbers satisfy this property. Therefore, if I wish to multiply 5 and 10, I can split this down to simplify the problem (or simply highlight the logical reasoning behind how long multiplication works.) To demonstrate:</span>

<span>5∗10=5∗(2+8<span>)=</span>5∗2+5∗8=10+40=50</span>

<span> </span>

Mr. Martin’s math test which is worth 100 points has 29questions. Each problem is worth 2points or 5 points. X represents number

adell [148]

Answer:there are 14 5point problems and 15 2point problems on the test.

Step-by-step explanation:

x represents number of 5 point questions and y represents questions worth 2 points.

The total number of questions in the test is 29. It means that

x + y = 29

x = 29 - y

Mr. Martin’s math test is worth 100 points. It means that

5x + 2y = 100 - - - - - - - - -1

Substituting x = 29 - y into equation 1, it becomes

5(29 - y) + 2y = 100

145 - 5y + 2y = 100

- 5y + 2y = 100 - 145

- 3y = - 45

y = - 45/-3

y = 15

x = 29 - y = 29 - 15

x = 14

The height of the given trapezoid is 7.5 m.

Step-by-step explanation:

Step 1:

The trapezoid's area is calculated by averaging the base lengths and multiplying it with the trapezoid's height.

The trapezoid's area, $A = \frac{b_{1}+b_{2}}{2} (h).$

Here $b_{1}$ is the lower base length and $b_{2}$ is the upper base length while h is the height.

Step 2:

In the given problem, $b_{1}=5 \mathrm{m}$ and $b_{2}=3 \mathrm{m}$ . Assume the height is h m.

The trapezoid's area $= 30.$

$30 = \frac{5+3}{2} (h), 30 = (4)(h).$

$h = \frac{30}{4} = 7.5.$

So the height of the given trapezoid is 7.5 m.
