Answer:
D. 46.5
Step-by-step explanation:
The formula to find the circumference of a circle is: 2πr
2(π x radius) or π times the diameter.
The radius is 7.4
7.4 x 2 = 14.8
14.8π ≈ 46.5
Answer:
x=3, y=5. (3, 5).
Step-by-step explanation:
6x+3y=33
3x-y=4
----------------
y=3x-4
6x+3(3x-4)=33
6x+9x-12=33
15x-12=33
15x=33+12
15x=45
x=45/15
x=3
3(3)-y=4
9-y=4
y=9-4
y=5

Answer:its algebra very simple all you want do is get x by itself
Step-by-step explanation:
you have to subtract from both sides 1
so then you'll have
4 x = (1 - x)
after that you divide by 4 from both sides you'll be left with
x = 1 - x
Answer:
36m
Step-by-step explanation:
The perimeter is given by
P = 2(l+w)
The length is 12 and the width is 6
P = 2(12+6)
P = 2(18)
P = 36
