Answer:

The value of x = 5 and the value of y = 9

Step-by-step explanation:

It is given that,

x = 5 -----(1)

y = 2x - 1 -----(2)

Using these two equations we can calculate the value of y using substitution method.

Substituting the value of x from eq(1) to eq(2)eq(2) becomes,

y = 2*5 - 1

y = 10 - 1

y = 9

Therefore the value of y = 9 and value of x = 5

Y is 9 because 2 times 5 is 10, then you take that same 10 and subtract 1 and then you have 9

(-2x-5)=23 solve for it step by step please

expeople1 [14]

Answer: $x=-14$

Step-by-step explanation:

Get rid of parentheses: $-2x-5-23=0$

Add all the numbers together, and all the variables: $-2x-28=0$

Move all terms containing x to the left, all other terms to the right:

$-2x=28$

$x=28/-2$

$x=-14$

what is the common ratio for the geometric sequence below, written as a fraction? 768, 480, 300, 187.5, …

Crazy boy [7]

Let

$a1=768\\a2=480\\a3=300\\a4=187.5$

Step $1$

Find $\frac{a2}{a1}$

$\frac{a2}{a1} =\frac{480}{768}$

Divide by $96$ numerator and denominator

$\frac{480}{768} =\frac{\frac{480}{96}}{\frac{768}{96}} \\ \\ \frac{480}{768}=\frac{5}{8}$

$a2=a1*\frac{5}{8}$

Step $2$

Find $\frac{a3}{a2}$

$\frac{a3}{a2} =\frac{300}{480}$

Divide by $60$ numerator and denominator

$\frac{300}{480} =\frac{\frac{300}{60}}{\frac{480}{60}} \\ \\ \frac{300}{480}=\frac{5}{8}$

$a3=a2*\frac{5}{8}$

Step $3$

Find $\frac{a4}{a3}$

$a4=187.5 \\ a4=187\frac{1}{2} \\ \\ a4=\frac{375}{2}$

$\frac{a4}{a3} =\frac{\frac{375}{2}}{300} \\ \\ \frac{a4}{a3} =\frac{375}{600}$

Divide by $75$ numerator and denominator

$\frac{375}{600} =\frac{\frac{375}{75}}{\frac{600}{75}} \\ \\ \frac{375}{600}=\frac{5}{8}$

$a4=a3*\frac{5}{8}$

In this problem

The geometric sequence formula is equal to

$a(n+1)=a(n)*\frac{5}{8}\\$

For $n\geq 1$

therefore

the answer is

the common ratio for the geometric sequence above is $\frac{5}{8}$

Solve equation<br>8-3(p-4)=2p

LenKa [72]

Answer:

ok the answer is: p=-4

Step-by-step explanation:

First you distribute 3 times p-4 and get 8-3p+12=2p then you add 12 plus 8 and get 20 then you have 20-3p=2p you have to add 3p on both sides and you get 20= -5p you divide and get p= -4

Answer:

<em>Probability ≈ 0.1071</em>

Step-by-step explanation:

Consider steps below;

$Total Possible Outcomes - 8C5,\\\\8! / 5! ( 8 - 5 )!,\\1 * 2 * 3 * 4 * 5 * 6 * 7 * 8 / ( 1 * 2 * 3 * 4 * 5 )( 1 * 2 * 3 ),\\\\6 * 7 * 8 / 6 = Combinations - 56,\\\\$

$Number Of Outcomes - 6C5,\\\\6! / 5! ( 6 - 5 )!,\\1 * 2 * 3 * 4 * 5 * 6 / ( 1 * 2 * 3 * 4 * 5 ) ( 1 ),\\720 / 120 * 1,\\\\Outcomes - 6$

$Conclusion ; Solution - 6 / 56 = ( About ) 0.1071\\Hope That Helps!$

<em>Solution; Probability ≈ 0.1071</em>
