Maria and farida has 250 beads altogether. after maria used 18 beads to make a bracelet 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

Step-by-step explanation:

Let x the number of beads Maria had

Let y the number of beads Farida had

We know because of the problem that

x + y = 250

x -18  = 3/5* y

x -3/5*y = 18

We solve this system of equation with a graphing tool

(intersection of both lines)

Answer

x = 105

y = 145

the thermometer is precise but not accurate

step-by-step explanation:

dalila is incorrect. the whisker on the left is very long, going all the way out to 5. the whisker goes from 5 to 30, so it has a spread of 25. the rest of the box plot values are closer together, so 5 is an outlier
