<em>Greetings from Brasil...</em>

Here is the problem:

[(15X - 8)/3] + [(9X - 3)/2]

<em>Let's multiply everything by 6</em>

[6.(15X - 8)/3] + [6.(9X - 3)/2]

[2.(15X - 8)] + [3.(9X - 3)]

30X - 16 + 27X - 9

<h3>57X - 25</h3>

Find the slope of the line passing through each of the following pairs of points and draw the graph of the line. (5, 2), (3, 3)
Strike441 [17]

Answer:

-0.5

Step-by-step explanation:

  • slope=rise/run or y/x in other words(y2-y1/x2-x1)
  • (y2-y1) is 3-2 so y2-y1=1
  • (x2-x1) is 3-5 so x2-x1= -2
  • -1/2 or -0.5 would be the slope.

Brett painted three walls. Each wall was 9 ft tall and 12 ft long. How much wall area did he paint
julsineya [31]

Answer:

First we need to calculate the are of each wall, since we alredy knew the length (l) and the width (w) which is the height of the wall in this case:

A = wl = 9 . 12 = 108 (ft²)

We also know that he painted 3 walls, we need to multiply our first result by 3, in other words, the area of wall that Brett painted is the sum of the area of three walls: 108 . 3 = 324 (ft²)

Explain how to find the sum of 3/10 + 4/100
Neporo4naja [7]

Answer: 17/50

Step-by-step explanation:

First, to add fractions, we must find a common denominator, in this case, 100.

Then, we must make the fractions being added all have the common denominator.

So, we must multiply 3/10 * 10/10, which equals 30/100

30/100 + 4/100

Then, just add across the numerator to get 34/100, which can be simplified to 17/50

In a class of 40 students, 5 like neither Nokia nor
Vikki [24]

Answer:

No student liked only Nokia

Step-by-step explanation:

The information can be illustrated as shown on the Venn diagram.

The number of students who liked only Nokia is x.

The sum of all regions in the Venn diagram should be 40.

We add all to get:

5 + 5 + 30 + x = 40

40 + x = 40

x = 40 - 40

x = 0

Therefore no one liked only Nokia
