Answer:
n=S+360÷180
Step-by-step explanation:
S=(n-2) 180
S= 180n-180*2
S=180n-360
180n-360=S
180n =S+360
180n÷180=S+360÷180
n=S+360÷180
Answer:
It'll have an open circle on both 7 and 21, with a line connecting.
Which is none of the options, unless one isn't shown?
Step-by-step explanation:
-23 > -4x + 5 > -79
So:
-23 > -4x + 5
-23 - 5 > -4x
-4x < -28
x > -28 / -4
x > 7
-4x + 5 > -79
-4x > - 79 - 5
-4x > -84
x < -84 / -4
x < 21
Exactly the same way you find any missing item in any other subject:
You take the information you're given, and you collect everything you know about
relationships between the information you have and the item you have to find.
Finally, you use the relationships and the given information to find the value of the
missing item.
The process you'll use to find the circumference of a circle will depend on what
information you DO have about the circle.
Answer:
95
Step-by-step explanation:
6 x 10 = 60
7 x 10 / 2 = 35
35 + 60 = 95
Answer:
y = - 3x + 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 3x + 8 ← is in slope- intercept form
with slope m = - 3
Parallel lines have equal slopes, then
y = - 3x + c ← is the partial equation
To find c substitute (2, - 1) into the partial equation
- 1 = - 6 + c ⇒ c = - 1 + 6 = 5
y = - 3x + 5 ← equation of line
