Solve -3 1/2= 1/2x + 1/2 x + x.

x = -1¾

Step-by-step explanation:

-3 1/2= 1/2x + 1/2 x + x.

-3½ = ½x + ½x + x

-3½ = (½+½+1) x.        (add coefficients of x together)

-3½ = 2x

2x = -7/2

Divide both sides by 2

2x/2 = -7/2  ÷ 2

x = -7/2 × 1/2

x = -7/4

x = -1¾

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
