Va rog rezolvati aceste exercitii va dau pana si coroana : (a:5+99:9)x(5214:33)=5530 98509-453x9+23x457=??? Suma a trei numere este 2356 Primul numar este 345,iar al doilea este dublul primului numar iar al treilea este (3912-638):89+a=121

a .4y4

hope this !

y + 11 = (1/4)(x + 16)

step-by-step explanation:

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72
