Maria and farida has 250 beads altogether. after maria used 18 beads to make a bracket and farida gave away 2/5 of her beads, they have the same number of beads left. how many beads did maria have at first?

Maria had 105 beads at first.

Step-by-step explanation:

Let number of beads Maria have be x.

Let number of beads Farida have be y.

Given:

Maria and Farida has 250 beads altogether.

Hence equation is represented as;

Also Given:

Maria used 18 beads to make a bracket.

hence bead left with maria =

farida gave away 2/5 of her beads.

Hence beads left with Farida =

Also they have the same number of beads left.

bead left with maria = beads left with Farida

Now Multiplying equation 1 with 3 we get;

Now adding equation 2 by equation 3 we get;

we know the value of x = 105

hence substituting value of x in equation 1 we get;

Maria had 105 beads and Farida had 145 beads at first.

Final Maria had 105 beads at first.

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.
