54 buttons ÷ 9 button cards = 6
She should buy 6 cards of buttons.
the answer is C
Use the distributive property
Answer:
5.
x + 2(x + 1) = 8 --> x = 2
y = 2 + 1 = 3
7.
3(9 + 2y) + 5y = 20 --> y = -7/11
x = 9 + 2(-7/11) = 85/11
9.
3(-1 - 2y) + 5y = -1 --> y = -2
x = -1 - 2(-2) = 3
Answer:
( 41° * π * radius) / 180
Step-by-step explanation:
The arc measure of major arc ABC on circle P is
( 41° * π * radius) / 180 degrees.
For instance if P = 5 then see the picture, the Arc Length = 3.58
S = r·α is the formula to find the arc length (s), given the radius (r), and angle measure (α) in radians.
If the angle measure is NOT given in radians you must convert to radians.
s = 8 · 2.6
s = 20.8 in
