Answer:
they had more people
Step-by-step explanation:
Alright because of P.E.M.D.A.S we want to start with the paranthesis but there is nothing we can do so we move on to exponents.
4^2 is 16
16(20-×)-8(x+3)=8 we need to distribute the numbers in front of the paranthesis across both number inside them.
320-16x-8x-24=8
now combine like terms
296-24x=8
now we need to isolate the variable so subtract 296 from both sides.
-24x=-288
now divide both sides by -24
x= 12
Answer:
Ф = 10°
Step-by-step explanation:
Regarding arc length, s: s = r·Ф, where Ф is the central angle in radians and r is the radius.
We need to find the central angle, Ф, in this problem.
We know that C = circumference = 6, and that this leads to r = 6/π.
Substituting 6/π for r and 1/3 for s in Ф = s / r, we get:
Ф in radians = 1/3 / (6/π), or Ф = π/18 rad.
π 180°
Converting this into degrees, we multiply ------ by ----------
18 π rad
obtaining: Ф = 10°
