Answer:

22°

Step-by-step explanation:

cos B = (c2 + a2 − b2)/2ca

cos B = ( $10^{2}$ + $6^{2}$ - $5^{2}$ )/ 2(10)(6)

cos B = .925

$cos^{-1}$ B = 22.33

The sum of two numbers is twenty-four. The difference of the two numbers is four.

RSB [31]

Answer:

$x + y = 24$

$x - y = 4$

Now, add these two equations.

You get,

$2x = 28$

$x = \frac{28}{2}$

$x = 14$

Given,

$x + y = 24$

$14 + y = 24$

$y = 24 - 14$

$y = 10$

You can test this to the other equation as well.

$x - y = 4$

$14 - 10 = 4$

Hence, the two numbers are 14 and 10.

Simplify -12x + 5x. -7 -7x -17x

Leno4ka [110]

7x. Try to ignore the X's for a second and think of the problem as -12+5 (aka 5-12). The answer to that is 7. now add the x back again to get: 7x
