║a+9║/7=5
you multiply 7 on both sides which cancel out 7.
now it ║a=9║=35
and now it would be a+9=35 and a+9=-35 then solve it.
35-9 and 9-(-35)= 26 and -44
hope this helped!

Answer:

the stock will sell for $59.16

Step-by-step explanation:

P0 = 2 * (1+0.2) / (1+0.105) + 2 * (1+0.2) * (1+0.12) / (1+0.105)^2 +

2*(1+0.2)*(1+0.12)^2 / (1+0.105)^3 +

[(2 * (1+0.2) * (1+0.12)^2 * (1+0.06) / (0.105-0.06)) / (1+0.105)^3 ]

P0 = $59.16

Answer:

5.5 yards.

Step-by-step explanation:

We have been given that Mimi needs eleven 18-inch pieces of rhinestone ribbon. She purchased 5 yards of the ribbon. We are asked to find the total amount of ribbon that Mimi needs.

First of all, we will multiply 11 by 18 to find amount of ribbon needed in inches as:

$\text{Amount of total ribbon in inches}=11\times 18\text{ inches}$
