What is the value of x?

enter your answer in the box

x =

The value of x is 20.

Step-by-step explanation:

Given two vertical angles (3x+50)° and (6x-10)°.

we have to find the value of x.

As we know vertically opposite angles are equal

∴ we can write both angles equal.

Hence, (3x+50)°=(6x-10)°

⇒ 3x+50=6x-10

⇒ 6x-3x=50+10=60

⇒ 3x=60

Divide by 3 on both sides, we get

x=20

Hence, value of x is 20

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

mean, 40.6
