tbh too lazy to explain
Answer:
28.26
Step-by-step explanation:
so your formula would be
C=πd
your subsition would be
c=3.14*9
so your finally answer would be
28.26
4xy^2 - 9x + 1 is of degree 3
Answer:
76 birds
Step-by-step explanation:
Let x = the number of birds
Let y = the number of cats
x + y = 35 y = 35 - x
4.50x + 8.50y = 221.50 Multiply the whole equation by 100.
450x + 850y = 22150
450x + 850(35 - x) = 22150
450x + 29750 - 850x = 22150
-100x = -7600
x = 76 birds

Answer:
(D) (170 -4x)°
Step-by-step explanation:
Angles 1 and 5 are corresponding, so are congruent. Angle 6 forms a linear pair with angle 5, so is its supplement. That is, angle 6 is the supplement of angle 1:
∠6 = 180° -(4x +1)° = (180 -1)° -4x°
∠6 = (179 -4x)° . . . . matches choice D
