Answer:
x=35
Step-by-step explanation:
3x+3=108
3x=108-3
3x= 105
x= 105/3
x=35
27. N > -1
29. T < 2
31. K= -12
33. 30= 4m + 2
Answer: m = 7
2z +7 = -5
2z = -5 -7
2z = -12
z= -12 /2
z= -6
10 i think i don't know how to deleat this so can u?
Answer:
Look at my explanation
Step-by-step explanation:
The circumference of a circle is 2πr, so you can set it up like this since the circumference was 22π.
2πr = 22π
divide both sides by 2
πr = 11π
divide both sides by π
you get r = 11
So your radius is 11.
To find the area, you must do πr^2 ("^2" means squared)
if you substitute 11 for r you get
11π^2
you can do 11 squared first
11^2 = 121
the area of the circle = 121π
Keep in mind that they said to use 3.14 for π
so you can do 121 x 3.14
