The two points are (1,30) and (7,55). Slope = the change in y/the change in x. Slope is -25/-6, which simplifies to 4.2.
as we move down the list as we push the *digits* to the *left*through the decimal *point* *each* *number has been 10*. and so we can easily *multiply* or divide by *a* power of *10* because of our system of positional numeration. Each Place belongs to the next power of *10*.
One angle = 360 / n
Let x be the angle and n be the number of sides.
x = 360 / n
nx = 360
now, let's use this:
(2n - 4 )*90 = 1260
2n - 4 = 1260 / 90
2n - 4 = 42 / 3
2n - 4 = 14
2n = 18
n = 9
x = 360 / 9
x = 40 degrees for each exterior angle
so the interior angle's measurement is 140 degrees
So 9 would be the answer

Answer:
Step-by-step explanation:
Answer:
5 packages
Step-by-step explanation:
One package of blackberries cost $3
Let x represent the number of packages that will cost $15
1 = $3
x= $15
3x= 15
Divide both sides by the coefficient of x which is 3
3x= 15/3
x= 5
Hence 5 packages of blackberries will cost $15
