Each variable used is the first letter of each of their names.
t+b+c=87
c=2t
b=t+7
Substitute for b and c
t+ (t+7)+2t= 87
4t+7=87
4t=80
t=20
Plug in the known t value.
c=2(20)
c=40
b=20+7
b=27
Final answer: Tammy=$20, Boris= $27, Carlos=$40
Answer:
Step-by-step explanation:
3x²+11x-4
when splitting the middle term
it becomes
3x²+12x-1x-4
=3x(x+4)-1(x+4)
(3x-1)(x+4)
either 3x-1=0 then x=1/3
or x+4=0 then x= -4
m=1/3
n=-4
therefore
value of m divided n plus n dividedm=1.25
