(4-5x)+43=3-32(-82)<br> please answer!!
kotykmax [81]

Answer:

x = -516

Step-by-step explanation:

(4 - 5x) + 43 = 3 - 32(-82)    {Multiply 32 and (-82)}

4 - 5x + 43 = 3  - (-2624)  

4 - 5x + 43 = 3 + 2624   {add 4 and 43 in LHS}

   -5x  + 47 = 2627      {Subtract 47 from both sides}

     -5x        = 2627 - 47

          -5x   = 2580         {Divide both sides by (-5)}

                x = 2580/(-5)

x = -516

DerKrebs [107]

Using it's concept, it is found that there is a 0.2426 = 24.26% probability that the person selected is between 26 and 35.

<h3>What is a probability?</h3>

A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.

Researching this problem on the internet, it is found that there is a table containing 1113 people, and out of 1113 people, 270 are between 26 and 35, hence the probability is given by:

p = 270/1113 = 0.2426.

PLEASE HELP WORTH 50 POINTS!
Scorpion4ik [409]
Jessica’s mistake is that when isolating h from b, she multiplied b instead of dividing it on both sides. The new formula for h would be A/2b=h.
Now let’s solve. 23/2(6)=h
23/12
