3x - 7 = 5x + 19
  |Equation|


-7=5x+19-3x
 
  |Subtract \ 3x \ from \ both \ sides| 


-7=2x+19
 
 


-7-19=2x
 
 

-26=2x 

-26/2=x 

x=-13

3x-7=5x+19
Add 7 to both sides.
3x=5x+26
Subtract 5x on both sides.
-2x=26
Divide by -2 on both sides.
x=-13


To check the answer you substitute x=-13 back into the equation.
3x-7=5x+19
3(-13)-7=5(-13)+19
-39-7=-65+19
-46=-46

P and Q are points on the line y= 2 -4x complete the coordinates of P and Q, P(0, ) Q( ,0)
docker41 [41]
(d): y=2-4x
P(0;y) belongs to (d)
=> y=2-4*0
= 2
So P(0;2)
Q(x;0) belongs to (d)
=> 0=2-4*x
<=> x=1/2
So Q(1/2;0)

5 &amp; 10/13 rounded to the nearest tenth ( A 5.7 B.5.2 C.5 D.4.5)
Black_prince [1.1K]
Hello!

ANSWER:

5 10/13 rounded to the nearest tenth is A) 5.7.
___________________________

EXPLANATION:

Convert 5 10/13 to an improper fraction.

First, multiply the denominator by the whole number:

5 × 13 = 65

Next, add that to the numerator:

65 + 10 = 75

This is the new numerator. Place it over the old denominator.

5 10/13 = 75/13

-------------------------------------------------------

Now, convert the improper fraction to a decimal by dividing its numerator by its denominator:

75 ÷ 13 = 5.7692307692

This can be rounded to 5.7.

An elevator containing 3 people can stop at any of the five floors. What is the probability that no two people get off at the sa
olasank [31]

Answer:

48%

Step-by-step explanation:

We have 3 people and 5 floors

We can't have two or more people leaving in the same floor.

So, the first person to leave has 5 possibilities (all 5 floors)

Then, the second person will have only 4 possibilities, as this person can't leave in the same floor as the first one.

Lastly, the third person will have only 3 options (the 3 remaining floors that weren't selected).

The total number of possible choices, without restrictions, is 5 possibilities for each person, so 5*5*5 = 125 combinations

The combinations we want is 5*4*3 = 60 combinations

So the probability of all people choosing different floors is 60/125 = 0.48 = 48%
