Step-by-step explanation:

18+18 = 36. 42-36 = 6. 6 / 2 = 3

s = 3

Step-by-step explanation:

2 sides measure 18 so

42- 18 - 18 = 6

2 sides  =  s

so 2s = 6

divide both sides by 2 and taaadaaa

s = 3

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
