Answer:

1.   4a + 5b;   2.  6p + 4r;    3.  -22y - 3x

Step-by-step explanation:

1. (4a + 5b) + (2a - 6b) - 2(a - 3b)

  (4a + 5b) + (2a - 6b)  + (- 2a + 6b)         Distributive

 (4a + 2a -2a) + (5b - 6b + 6b)                 Combine like terms

  4a + 5b

 2.  2(5p - q + 2r) - (p + 4q + 3r) - 3(p -2q - r)  

       10p - 2q + 4r - p - 4q - 3r - 3p + 6q + 3r

       (10p - p -3p) + (-2q - 4q + 6q ) + ( 4r - 3r + 3r)

         6p + 0 + 4r

          6p + 4r

3.    - (9y + x) + 2(x - 6y) - (4x + y)

         -9y - x  + 2x - 12y - 4x - y

        (-9y -12y -y) + (-x + 2x - 4x)

           -22y - 3x

What is the value of x in the nearest whole number​
MAXImum [283]

Answer:

16

Step-by-step explanation:

To calculate x we must use the trig function of tangent:

as tangent is opposite divides by adjacent we can get this equation:

\tan 30 = \frac{9}{x} which is equal to:

x=\frac{9}{\tan 30} So x must equal to 15.588.. (just put the second bit in the calculator

As all the values provided are integers you round this to the nearest whole number:

16 (as the third digit, 5, rounds up)

so our answer is 16

Solve each system by elimination.<br> 1) 10x + 7y=9 -4x - 7y=9
stellarik [79]

Answer:

(3, -3)

Step-by-step explanation:

When asked to solve by elimination, you put them on top of one another, like you're going to add it.

10x + 7y = 9

-4x - 7y = 9

See that 7y? You can cancel those out because one is negative, and one is positive. So those are gone. You finish adding the rest of the numbers as usual and solve for x.

6x = 18

x = 3

Take x, and plug it into either equation to find y.

10(3) + 7y = 9

7y = -21

y = -3

(3, -3)

Hope this helped!
