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

a(b+c)=ab+ac

The whole numbers are a subset of the field 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:

5∗10=5∗(2+8)=5∗2+5∗8=10+40=50

Bob has some 10 lb weights and some 3 lb weights. Together, all his weights add up to 50 lbs. If x represents the number of 3 lb

olga2289 [7]

Answer:

3x = 50 - 10y

Step-by-step explanation:

Here, x represents the number of 3 lb weights and y represents the number of 10 lb weights,

So, total weight of 3 lb weights = 3x

And, the weight of 10 lb weights = 10y

Total weight of all his weights = 3x + 10y

According to the question,

Total weight = 50 lb,

⇒ 3x + 10y = 50

Or 3x = 50 - 10y

Which is the required equation.

Second option is correct.

In a certain Algebra 2 class of 29 students, 14 of them play basketball and 8 of them play baseball. There are 9 students who pl

EastWind [94]

Answer:

2/29

Step-by-step explanation:

If 9 play none, of the 29 students, 29-9 =20 play at least one. If 14 play basketball, then 20-14 = 6 play only baseball. Since 8 play baseball, there must be 8-6 = 2 who play both baseball and basketball.

Choosing at random, the probability is 2/29 that a student will be chosen who plays both sports.
