<h3><u>Answer:</u></h3>
  • -52x + 30 is the evaluated expression.
<h3><u>Step-by-step explanation:</u></h3>
  • 10(-5x + 3) - 2x
  • => -50x + 30 - 2x
  • => -52x + 30
<h3><u>Conclusion:</u></h3>

Hence, -52x + 30 is the evaluated expression.

Hoped this helped.

Step-by-step explanation:

well, we just do the multiplication and simplify by combining terms with the same base :

10(-5x + 3) - 2x = -50x + 30 - 2x = -52x + 30

5. Using only odd numbers for numerators,
Lady bird [3.3K]

Answer:

  • 3/4 - 1/4 = 1/2
  • 5/8 - 1/8 = 1/2

Step-by-step explanation:

You can pick just about any fraction with an odd numerator and find another at distance 1/2 from it.

For example, 5/7 - 1/2 = 10/14 - 7/14 = 3/14. So your subtraction problem can be ...

  5/7 - 3/14 = 1/2

Choosing a denominator divisible by 4 can make both parts of the problem use the same denominator.

  3/4 - 2/4 = 1/4, so the corresponding subtraction problem is 3/4 - 1/4 = 1/2.

  5/8 - 4/8 = 1/8, so the subtraction problem is 5/8 -1/8 = 1/2.

Suppose n(x)= 22 and n(y) is 13 what is the maximum number of elements X ∪Y can have ?
Nikolay [14]
The inclusion/exclusion principle states that

|X\cup Y|=|X|+|Y|-|X\cap Y|

That is, the union has as many members as the sum of the number of members of the individual sets, minus the number of elements contained in both sets (to avoid double-counting).

Therefore, |X\cup Y| will have the most elements when the sets X and Y are disjoint, i.e. X\cap Y=\emptyset, which would mean the most we can can in this case would be

|X\cup Y|=|X|+|Y|=22+13=35

(Note that n(X)=|X| denotes the cardinality of the set X.)
