Find the mistake and correct it
Murljashka [212]

Answer:

i believe its the second part thats wrong  

Step-by-step explanation:

1 Distribute

−5(−2+10)=20

10−50=20

2 Add 50 to both sides of the equation

10−50=20

10−50+50=20+50

3 Simplify

Add the numbers

10x−50+50=20+50

10=20+50

Add the numbers

10x =20 + 50

10x=10

4 Divide both sides of the equation by the same term

10x = 70

10x   70

---- = ----

10      10

5 Simplify

Cancel terms that are in both the numerator and denominator

10x   70

---- = ----

10      10

      70

x  = ----

       10

   

        70

x  = ----

       10  

x=7

Solution

= 7

hopes it helps and list brain list plz

1/2 o 50%

Step-by-step explanation:

debemos partir de la presuncion que un bebe puede ser niño o niña uinicamente, o sea la P(niño) + P(niña) = 1

no existen los bebes que son niños y niñas al mismo tiempo, eso quiere decir que es una opcion o la otra

P(niña) = 1 - P(niño) = 1 - 1/2 = 1/2 = 0.5 = 50%
