180(n-2)=157.5n
180N-360=157.5n
180N-157.5n=360
22.5N=360
N=360/22.5
N=16
Answer:
a.
b.
c.
d.
11, 3, 31, 11 = code
Step-by-step explanation:
a. * 2 =
2 = =
* = =
b. / =
* = = =
c. * = (you can reduce 8 & 56 by dividing by 8: 56/8=7 & -8/8= -1)
d. 1 / 2 =
1 = =
* = (you can reduce 15 & 30 by dividing by 15: 15/15=1 & 30/15 = 2)
Plot these points:(-2,-7) (-1,-5) (0,-3) (1,-1) (2,1) (3,3) (4,5)
You need to substitute your x values into the x of the equation y=2(3)-3 to find the y value...
slope = - 2 and y- intercept = 6
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 2x + 6 ← is in slope- intercept form
with slope m = - 2 and y- intercept c = 6
1 in 7
Your one-digit choices: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.
But they're nonzero, so: 1, 2, 3, 4, 5, 6, 7, 8, 9.
But they can't be repeated and 9 and 8 are used, so: 1, 2, 3, 4, 5, 6, 7.
Only 7 numbers left, so chances are, 1 in 7.
