Games: $471; System: $157
s = cost of the system, and g = cost of the games
It is given that s+g = 628
and g=3*s
s+3*s = 628
4s = 628
s = 157
s+g = 628
157+g= 628
g= 628-157
g= 471

Answer: A- Selena is incorrect because she should have substituted the values for the variables first, and then simplifed
i just took the test. i know that drake is correct because his finale answer was -1/2 and Selenas finale answer was 1/2 if she would have substituted her vaules before simplifying she would have gotten the answer 1/-2 instead of -1/-2 which resulted in her finale answer to be 1/2
Step-by-step explanation:
If triangles ADB and EDC are similar, then corresponding sides are proportional, from which we conclude:
BC/CD = AE/ED
BC / 21 = 6 / 18
Multiply by 21 on both sides,
BC = 6*21 / 18 = 21 / 3 = 7 units.
(note: Length BC is the same as length CB).
