< To solve the inequality < 5 we must
multiply both sides by a negative number!
What must we do to the inequality symbol?
<5.-4
<-4
A. We must FLIP the inequality symbol. Our answer will be x > -20.
B. We must change the inequality symbol to an equal sign. Our
answer will be x = -20.
C. We don't need to do anything to the inequality symbol. Our
answer will be x < -20.

step-by-step explanation:

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

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