Answer:

1) x = 208     2) n = 28

Hope this helps! Have a great day!!

Step-by-step explanation:

1)

x  -  72  =  136

    +  72      +72

x             =    208

2)

 n  -  10  =  13  +  5

 n  -  10  =  18

       +10       +10

<h3>Hello There today we will solve your problem,</h3>

First off we will use our definitions so you know what do to next time and make it easier,

<h3>Definition</h3>

Algebra - <em>the part of mathematics in which letters and other general symbols are used to represent numbers and quantities in formulae and equations.</em>

<em>_______________</em>

<em>Now we can start!</em>

\huge\blue{\mid{\fbox{\tt{NUMBER\:ONE}}\mid}}

  • x-72=136

Add 72 to both sides,

<u><em>Answer</em></u><em> </em><u><em>:</em></u><em> </em>x=208

\huge\blue{\mid{\fbox{\tt{NUMBER\:TWO}}\mid}}<em />

  • <em />n-10=13+5

Simplify ⇒ 13+5 ⇒ 18

  • n-10=18

Add 10 to both sides

<u><em>Answer</em></u><em> </em><u><em>:</em></u><em> </em>n=28

A card is drawn at random from a well-shuffled deck of playing cards. Find the probability that the card drawn is (i)a card of s
docker41 [41]
There are 52 cards in a standard deck so that would be the whole in the part/whole equation so
i... There are 13 spade cards and then 3 other aces since there are 4 suits of cards so 16/52 or about 0.30769 or 30.8% rounded

ii....There are 2 reds of each card in a standard deck along with 2 blacks so there would be 2 red kings which would be a 2/52 chance or about 0.0384 or 3.8% rounded

iii.... There are 4 kings and 4 queens in each deck so (52-8)/52 which is a 44/52 chance, 0.8461 about, or 84.6% rounded

iv..., As I said in iii, there are 8 kings and queens so an 8/52 chance, about 0.1538, or 15.4% rounded

"I am 3 times as old as Sue is," Frank said to Ann. "On the other hand, I am 15 years older than John while Sue is 1 year younge
ahrayia [7]

Frank = F

Sue = S

John = J

F=3*S

F = J+15

S = J-1

If you want to find Frank's age, then his age would be equivalent to John's plus 15 years.

A.-Would not work because Frank is three times Sue's age, not John's (left hand side of the equation).

B.-Notice that the right hand side of the equation is equivalent to Sue's age, which we know is John-1, however it is currently written to be "three times Sue's age minus one" which would give us John's age, plus two more years than his actual age on the left hand side.

C.-Frank's age is equal to John's plus fifteen (right side of the equation) and Frank is equal to Sue's age times 3. But, if Sue is in terms of Johns, then Sue's age is John's minus one. Therefore, Frank's age is equal to three times Sue's age of John minus one, which is the left-hand side of our equation.


Therefore C is the answer. C:

\bf \cfrac{x^2-x-42}{x-6}\implies \cfrac{(x+7)\underline{(x-6)}}{\underline{x-6}}\implies x+7

so.. the left-hand-side does indeed simplify to x+7, so the equation does check out.

however, notice something, for the equation of x+7, when x = 6, we get (6) + 7 which is 13.

BUT for the rational, we get    \bf \cfrac{x^2-x-42}{x-6}\qquad \boxed{x=6}\implies \cfrac{x^2-x-42}{\boxed{6}-6}\implies \stackrel{und efined}{\cfrac{x^2-x-42}{0}}

so, even though the siimplification is correct, the rational or original expression is constrained in its domain.
