The value of x is_degrees.

x = 21

Step-by-step explanation:

The angle marked (6x - 21) and the angle marked 75 are supplementary angles. This means that they add up to 180 (by definition). We know this because they lie on a straight line, and a straight line is always 180 degrees. Then we can set up an equation:

(6x - 21) + 75 = 180

6x + 54 = 180

6x = 180 - 54 = 126

x = 126/6 = 21

Thus, x = 21.

Hope this helps!

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
