Answer:
17. m=-1/2
18. m=-1
Step-by-step explanation:
Answer:
C.
Step-by-step explanation:
To answer this, we first have to make common denominators. to do this, we do (5/4) x 5 and (3/5) x 4, to get new fractions, 25/20, and 12/20. then, we can subtract 25/20 and 12/20 easily to get the remaining liters, 13/20. Then, to pick the right model, we need to find which box(es) has 20 squares in it, which are Boxes A and C. Now, we can just count which one contains 13 filled-in squares, which is Box C. So that is our answer, C.
M + f = 250 ;
m - 18 = ( 3 / 5)f ;
5m / 5 - 90 / 5 = 3f;
5m - 90 = 3f ;
5m - 3f = 90;
But, f = 250 - m;
5m - 3( 250 - m ) = 90 ;
5m - 750 + 3m = 90 ;
8m = 840;
m = 840 ÷ 8 ;
m = 105( beads for Maria );
f = 250 - 105 ;
f = 145 ( beads for Farida ) ;
