Answer:

x = 3

Step-by-step explanation:

First, multiply all four terms by 10 to eliminate the fractions:

4x - 8(x-4) = 13x - 19

Next, carry out the indicated multiplication, obtaining:

4x - 8x + 32 = 13x - 19

Combining the x terms, we get:

-4x + 32 = 13x - 19, or

        32 = 17x - 19

Combining the constants, we get 51 = 17x, and so x = 51/17 = 3.

Answer: B. $29.25

Step-by-step explanation:

  • In integers loss is represented by negative integers whereas profit is represented by positive numbers.

Given, Beginning price =  $24.75

Over the next 5 days,

On Monday, gain of  $2.50 represented by + $2.50.

On Tuesday, loss of $3.25 represented by - $3.25 .

On Wednesday,  loss of $0.75 represented by - $0.75.

On Thursday, gain of $1.25 represented by + $1.25.

On Friday, gain of $4.75 represented by + $4.75.

Price of the share of stock at the end of Friday = (Beginning price)+ ( + $2.50 - $3.25- $0.75+ $1.25+ $4.75)

= $( 24.75 + 2.50 -3.25 -0.75 +1.25 +4.75)

= $29.25

Hence, the correct option is B. $29.25.

Clara says that if you square the number 4 and then divide the result 2, you end up with 4. Is Clara correct? Explain.
sertanlavr [38]
Clara is incorrect. When you do the math, 4 squared is basically saying multiply four times four. Which equals Sixteen. When you divide Sixteen by two you get eight, not four. My math is listed below.

4^2 (4 • 4) = 16

16/2 = 8

Hopefully this helped and good luck!!
