Melissa, Charlie, and Josh have a total of $90 in their wallets. Josh has 3 times what Charlie has. Melissa has $10 less than Ch
arlie. How much does each have?
1 answer:
Answer:$20 = Charlie, $60 = Josh, $10 = Melissa
Step-by-step explanation:
M+C+J=90 = Melissa, Charlie, and Josh have a total of $90 in their wallets
J=3C = Josh has 3 times what Charlie has
M=C-10 = Melissa has $10 less than Charlie.
Therefore
M+C+J=90
(C-10) + C + 3C=90
5C-10=90
5C=100
C=20 = Charlie
J=3C = 60 = Josh
M=C-10 = 10 = Melissa

Step-by-step explanation:
4 x 3 + 6
12 + 6
= 18

4 x 9
= 36
depends whether the 3+6 is in brackets :)
Perpendicular = Negative Reciprocal
-3 --> -1/3 ---> 1/3
Therefore it is C
