Use the Distributive Property to solve the equation. 3x-5(x-4)=-9+5x+15

Norma-Jean [14]

Answer:

I keep getting no solution

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

5(x−4)=−9+5x+15

(5)(x)+(5)(−4)=−9+5x+15(Distribute)

5x+−20=−9+5x+15

5x−20=(5x)+(−9+15)(Combine Like Terms)

5x−20=5x+6

Step 2: Subtract 5x from both sides.

5x−20−5x=5x+6−5x

−20=6

Step 3: Add 20 to both sides.

−20+20=6+20

0=26

Previous Question Question 14 of 20 Next Question A company randomly surveys 15 VIP customers and records their customer satisfa

Ann [662]

Answer:

71.4699, 81.7301.

Step-by-step explanation:

So, the following are the scores: 74

$Let,\;the\;total\;sum\;of\;the\;scores\;be:\sum x =1149$

$Then,\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\;\sum x^2=89795$

The length of the score : 15

Then, let the size of the scores be n : 15.

Then, we have to find the mean.

$\bar{x}=\frac{\sum x}{n}$

$=\frac{1149}{15}=76.6$

$Then,\;we\;have\;to\;find\;standard\;deviation:S=\sqrt{\frac{\sum x^2-n.(\bar{x})^2}{n-1} }$

$=\sqrt{\frac{89795-15\times(76.6)^2}{15-1} }=11.2808$

$The\;degree\;of\;freedom:n-1=14$

$So,\;the\;significant\;level:\alpha=1-0.90=0.10$

$and\;the\;critical\;value:t_{\frac{\alpha}{2} }=1.7613$

$Finally:\\=\bar{x}\;\pm\;t_{\frac{\alpha}{2} }\;\frac{S}{\sqrt{n} }\\=(71.4699, 81.7301)$
