Answer from: ryliefitz32
There are 68 total points.
Let the points held by the contestants be
x for Eric,
y for Sheena,
z for Yael.

Therefore
x + y + z = 68              (1)

Sheena has three fewer points than Yael, Therefore
y = z - 3  or
 y - z = -3                    (2)

Eric has half as many points as Sheena. Therefore
x = (1/2)y, or
2x = y                      (3)

Add (1) and (2).
x + 2y = 65               (4)

Substitute (3) nto (4).
x + 2(2x) = 65
5x = 65
x = 13
y = 2x = 26

From (2),
26 - z = -3
z = 29

 Yael has 29 points

Answer from: Quest

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8
