Answer:
5
Step-by-step explanation:
Adults = x
Students = y = x + 40. 40 more student than adult
Adult = $8, Student = $6
Total for Adults = 8*x = 8x
<span>Total for students = 6*y = 6y
</span>
Total = $1920
8x + 6y = 1920
Hence system of equations are:
<span>y = x + 40
</span>
<span>8x + 6y = 1920</span>
Answer:
0
Step-by-step explanation:
(10-1=9)(10-2=8)(10-3=7)(10-10=0)
9*8*7*0=0
Let's evaluate explicitly 
:
If this must equal 
, we have
Answer:
3(x + 4)
Step-by-step explanation:
Factor out a 3 from both terms, since 3 and 12 are both divisible by 3.
3x + 12
3(x + 4)
So, the factored expression is 3(x + 4)
