2. simplify each expression.
a.5+5 (24 +12)3

5+5=10  24+12=36^3 = 46,656

Step-by-step explanation:

So will start off with the Left Side which begins with 5+5= 10

Right Side (24+12)3  So we will add what is in the Parantheses  24+12=36

36^3  is 46,656

51-50

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
