Which equation is correctly rewriitten to solve for x
x/r - s = t

x/r - s = t

Add s to both sides.

x/r - s + s = s + t

x/r + 0 = s + t

x/r = s + t

Multiply both sides by r.

r(x/r) = r(s + t)

x = r(s + t)

step-by-step explanation:

find the angular size of the equatorial radius of the earth, if the horizontal parallax of the sun

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
