tom sold half of his comic books and then bought six more. he now has 12. how many did he begin with?

Answers

b=books
Sold half of book: b/2
Bought six more: b/2+
Now has 12: b/2+6=12
Subtract 6 on both sides: b/2+6-6=12-6
b/2=6
Multiply both sides by 2: b=12
Answer= 12 books

The formula for the area of a trapezoid is A=1/2h (b1+b2) express b1 in terms of A, h, and b2

Answers

A=1/2h(b₁+b₂)
1/2h(b₁+b₂)=A
(b₁+b₂)=2A/h
b₁=2A/h - b₂

answer: b₁=2A/h  -  b₂

0.7(3s+4)−1.1s=7.9 I need a answer

Answers

First, expand the bracket

2.1s + 2.8 - 1.1s = 7.9

Next, collect like terms

s + 2.8 = 7.9

Lastly subtract 2.8 from 7.9 to get your answer.

s = 5.1

(Hope this helps! ^^)

Answer:

\boxed {s = 5.1}

Step-by-step explanation:

Solve for the value of s:

0.7(3s + 4) - 1.1s = 7.9

-Use Distributive Property:

0.7(3s + 4) - 1.1s = 7.9

2.1s + 2.8 - 1.1s = 7.9

-Combine like terms:

2.1s + 2.8 - 1.1s = 7.9

s + 2.8 = 7.9

-Subtract 2.8 to both sides:

s + 2.8 - 2.8 = 7.9 - 2.8

\boxed {s = 5.1}

So, the value of x is 5.1.

A share of stock in the Bree Medical Supply Company is quoted at 35 1/4 . Suppose you hold 20 shares of that stock, which you bought at 31 1/2. If you sold your stock at 35 1/4, which of the following would be true? A. You suffered a loss of $75.00.
B. You made a profit of $705.00.
C. You suffered a loss of $630.00.
D. You made a profit of $75.00.

Answers

In the given question, there are several information's of immense importance. The information's are:
Cost Price of a stock of Bree Medical Supply = 31 1/2
                                                                         = 63/2 dollars
Cost at which the 20 stocks of Bree Medical Company bought = (63/2) * 20
                                                                                                     = 630 dollars
Sale price of each stock = 35 1/4 dollars
Sale price of each stock = 141/4 dollars
Sale price of 20 stocks = (141/4) * 20
                                      = 705 dollars
Then amount of profit made = (705 - 630) dollars
                                              = 75 dollars
So it can said that the statement you made a profit of $75 and so option "D" is the correct option.

 b6x3 + 3x + 2
 c2x3 + 3x + 2
  d6x3 − 3x − 2

Answers

Answer:

Option (b) is correct.

Step-by-step explanation:

Given: Polynomial 2x^3-5x-1 and 4x^3+8x+3

We have to find the sum of given polynomial and choose the correct option from given options.

Consider the given Polynomial 2x^3-5x-1 and 4x^3+8x+3

We have to find the sum that is 2x^3-5x-1+(4x^3+8x+3)

Apply plus minus rule +(-a)=-a

We have,

2x^3-5x-1+4x^3+8x+3

Now adding like terms, we have,

Like terms are terms having same variable with same degree.

(4+2)x^3+(8-5)x-1+3

Simplify , we have,

6x^3+3x+2

Thus, option (b) is correct.
(2x3 − 5x − 1) + (4x3 + 8x + 3)
=6x^3 +3x +2

answer is  b. 6x3 + 3x + 2
