2/3 of a number -11. Please help
vfiekz [6]

Answer:

(2/3)x = -11

x = -33/2

Step-by-step explanation:

2/3 of a number is -11.

Let the unknown number be x.

2/3 of x is -11.

(2/3)x = -11

Multiply both sides by 3/2.

(3/2)(2/3)x = (3/2)(-11/1)

x = -33/2

A loan of $12,000 is made at 5.25% interest, compounded annually. After how many years will the amount due reach $22,000 or more
yaroslaw [1]

Answer:

About 16 years

Step-by-step explanation:

First we need to figure out 5.25% of 12000

5.25 x 0.12000 = 0.63

Then we move the decimal

630

Then we need to figure out how many years it will take to reach $22000

Since we already owe $12000, we can just divide using $10000 because 10000 + 12000 = 22000

10000/630 = 15.87

Which is about 16 years
