Answer:
Step-by-step explanation:
T = x
S = 2x
J = 15
x + 2x + 15 = 63
3x = 63 - 15
3x = 48
x = 16
Tim has 16 marbles, Sue has 32 marbles and Jim has 15 marbles

How do you do the problem
Answer:
For each player:
Headbands = 11.67 inches of fabric
Wristbands = 9.31 inches of fabric
Step-by-step explanation:
Shauna is making accessories for the soccer team
For Headbands
She uses 513.48 inches of fabric on headbands for 40 player and 4 coaches
The total number of persons = 40 players + 4 coaches
= 44 persons
Hence:
44 persons = 513.48 inches
1 person = x
Cross Multiply
44x = 513.48 inches × 1
x = 513.48 inches/44
x = 11.67 inches per person
For Wristbands
She uses 372.40 inches of fabric on wristbands for just the players how much fabric was used on a headband and wristband for each player?
Number of players = 40
Hence
40 players = 372.40 inches
1 players = x inches
Cross Multiply
40x = 372.40 inches
x = 372.40 inches/40
x = 9.31 inches
Hence, 9.31 inches per player.
Therefore
For each player:
Headbands = 11.67 inches of fabric
Wristbands = 9.31 inches of fabric
<span>-1<0
so use 2x+1
2(-1)+1=-2+1=-1
-
</span><span>F(-1) means "Evaluate F(x) when x=-1"
Since -1 is less than 0, this means that F(x) = 2x+1. This is because F(x) = 2x+1 when x < 0</span>
