Use the commutative and associative properties of addition to change the order and grouping of the addends. Then, combine like terms.
Example: 7w + 16 + 6w - 9+ 2w = (7w + 6w + 2w) + (16 - 9) = 15w +7
Use the properties of addition to simplify this expression. 9 +5 - 3t+6

what is the approximate angle of acb if abc is 25cm and the length of segment bc is 15

step-by-step explanation:

16

step-by-step explanation:

0.038

step-by-step explanation:

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33
