-(-5 - 6x) = 4 (5x +3)
tatiyna

-(-5 - 6x) = 4 (5x +3)

Pretend that there is a -1 in front of the first bracket

-1(-5-6x)= 4(5x+3)

Mutiply the first bracket by -1

(-1)(-5)(-1)(-6x)= 5+6x

Mutiply the second bracket by 4

(4)(5x)(4)(3)= 20x+12

5+6x= 20x+12

move 20x to the other side

5+6x-20x= 20x-20x+12

5+6x-20x= 12

5-14x= 12

move 5 to the other side

sign changes from +5 to -5.

5-5-14x= 12-5

-14x=7

divide by -14

-14x/-14= 7/-14

x= -1/2

Answer: x= -1/2

A boat travels 30 miles due North and then turns and travels 40 miles due
Elan Coil [88]

Answer:

50 miles

Step-by-step explanation:

This represents a 3-4-5 right triangle, where 3-4-5 is the ratio. Multiply those numbers by 10 to get 30-40-50. 30 and 40 are already in the problem, so 50 is the answer.

a concert promoter sold 475 tickets to a rock concert the ticket prices for different seat locations were 10 15 and 20 the total
Andrej [43]

282.5 of 10 tickets were sold in the rock concert by the promoter

<h3>How to determine the number of 10 tickets?</h3>

To do this, we make use of the following representations:

  • x represents the 10 tickets
  • y represents the 15 tickets
  • z represents the 20 tickets

The 475 tickets that were sold means that:

x + y + z = 475

The income means that:

10x + 15y + 20z = 6300

Also, we have:

10y = 4z

Divide both sides by 10

y = 0.4z

Substitute y = 0.4z in 10x + 15y + 20z = 6300

10x + 15*0.4z + 20z = 6300

10x + 6z + 20z = 6300

Evaluate the like terms

10x + 26z = 6300

Substitute y = 0.4z in x + y + z = 475

x + 0.4z + z = 475

Evaluate the like terms

x + 1.4z = 475

Make x the subject

x = 475 - 1.4z

Substitute x = 475 - 1.4z in 10x + 26z = 6300

10(475 - 1.4z) + 26z = 6300

Expand

4750 - 14z + 26z = 6400

Evaluate the like terms

12z = 1650

Divide both sides by 12

z = 137.5

Substitute z = 137.5 in x = 475 - 1.4z

x = 475 - 1.4 * 137.5

Evaluate

x = 282.5

Hence, 282.5 of 10 tickets were sold

You own 50 of Xenon Corporation's 5500 Shares. You purchased them at $75 each. The company decides to issue a dividend of 55,000
Advocard [28]

Answer:

Step-by-step explanation:

Your first step is to figure out how much money each share gets. In other words, what's their cut of the dividend?

Formula

Dividend / share = Total dividend / Total number of shares.

ROI = dividend / Cost  * 100

Givens

# shares owned = 50

Total shares issued = 5500

Dividend total = 55000

Cost of 1 share = 75

Note Not all the information is needed.

Solution

dividend / share = 55000 / 5500

dividend / share = 10 dollars.

ROI = 10/75 * 100

ROI = 13.3 %
