-4(x + 6) = -40 pls help!

x = 4

Step-by-step explanation:

-4*(x + 6) = -40

Multiply both sides by (-1/4):

(-1/4)*(-4)*(x + 6) = (-1/4)*(-40)

Simplify both sides:

x + 6 = 10

Transfer 6 to the right and change the sign of 6 ( 6 --> -6):

x = 10 - 6

Simplifiy one more time:

x = 4

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

answer: y=4000x+14000
