step-by-step explanation:

the word superfluous means unnecessary

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

so, after 10 years : rick has $1400 and sally has $1500

y=-2.5x+12.5

step-by-step explanation:

5y=2x+10

y=0.4x+2

slope=-2.5

5=-2.5*3+b

b=12.5
