Answer:
angle AOD = 90⁰
BOD = 3x⁰
90⁰+3x⁰ = 180⁰( being straight angle)
3x = 180⁰-90⁰
3x = 90⁰
x = 90⁰/3
x = 30⁰
now
y⁰+139⁰ = 180⁰(being straight angle)
y⁰ = 180⁰-139⁰
y⁰ = 41⁰
Answer:
p - 5q = 4qr where
q = 4 and r = -1 by applying these value
p - 5(4) = 4(4)(-1)
p - 20 = -16
p = -16 + 20
p = 4
Answer:
the probability is 
Step-by-step explanation:
there are 4 numbers on a 12 sided die that can be divided by 3: 3, 6, 9, and 12.
so the probability would be
, or 
Answer:
C) y=3
Step-by-step explanation:
4y squared - 7y = 15
4(3) squared -7(3)=15
4(9) -7(3)=15
39-21=15
15=15
