What is x+ (5x-18)+90 degrees

Mathematics

sweet [91]2 years ago
5 0

As this is an expression, not an equation, you cannot find a value for x. We can combine like terms, as follows:

x + (5x - 18 ) + 90

x + 5x - 18 + 90

6x - 72 or 6(x-12) : simplest form of this expression

Problem 3
Murljashka [212]

Answer:

-\frac{2}{5}

Step-by-step explanation:

Given expression:

           2x + 5y = -10

The equation of a straight line is;

            y = mx + c

y and x are the coordinates

m is the slope

c is the intercept

 Now;

          let us write the given expression in slope intercept format;

            2x + 5y  = -10

                    5y = -2x - 10

                     y = -\frac{2x}{5}  - 2

So, the slope of the line is -\frac{2}{5}

amanda, bryan, and colin are in a book club. amanda reads twice as many books as bryan per month and colin reads 4 fewer than 3
lesya [120]
Please see below solution:
Let x = number of books that Bryan reads2x  for amanda = Amanda 3x - 4 for Colin  Amanda = 5/8(Bryan + Colin)2x = 5/8(x+3x-4)2x = 5/8(4x-4)

[16x = 5(4x-4)]816x = 20x - 20Subtract 20x from each side-4x =-20-4x/-4= -20/-4 divide -4 to eliminate the -4 in -4xx = 5
Therefore:
Bryan reads 5 books a month.
Since Amanda reads twice as many books a Bryan read so Amanda 10 books a month. 
And Colin 11 books a month. 3(5) - 4 = 11

What is the value of x?<br> Enter your answer in the box.
loris [4]

Answer:

35

Step-by-step explanation:

Since all the angles are the same in this triangle, all the sides should be the same too.

Hence, 3x - 5 = 4x - 30

5 + -1x = -30

-1x = -35

x = 35

Hope this helped!
