Answer:

m=20

Step-by-step explanation:

Solve the equation:

7m - 8 = 3 ( 2 m + 4)

Multiply 3 and (2m+4)

7m - 8 = 6m + 12

Add 8 to each side

7m = 6m + 20

Subtract 6m from both sides

m = 20

Sadie is 3 years older than Kareem, and Kareem is twice as old as Nadra. The sum of their ages is 33.
Dima020 [189]

Answer:

Step 1-Write an equation, letting x represent Kareem’s age:

(x + 3) + x + 2 x = 33

Step 2-Solve the equation:

(x + 3) + x + 2 x = 33. 3 + 4 x = 33. 4 x = 30. x = 7 1/2.

Step 3-Sadie is 10 1/2, Kareem is 7 1/2, and Nadra is 3 3/4.

Which corrects the student’s first error?

1. In Step 1, the student should have used One-half x to represent Nadra’s age, and written the equation (x + 3) + x +1/2x = 33.

2. In Step 2, the student should have added 3 on both sides of the equation to find a solution of x = 9.

3. In Step 3, the solution represents Sadie’s age. Therefore, Sadie is 7 1/2, Kareem is 4 1/2, and Nadra is 2 1/4.

4. In Step 3, Nadra’s age is the difference between 33 and Sadie’s and Kareem’s ages, so Nadra is 15.

Solve the following dividend problem.
brilliants [131]

A.

To get dividend per share, we need to divide total dividend by total numbers of shares outstanding.

Dividend per share = \frac{40,000}{50,000}=0.8 dollars.


B.

Since per share you get $0.8, for 100 shares you will get 0.8*100=80 dollars.

Also, that is \frac{80}{40,000}*100=0.2 percent of the total dividends.


ANSWER:

A. $0.8 per share

B. $80 (and that is 0.2% of total dividend)
