Complementary angles add up to 90 degrees
m < 1 + m < 2 = 90
x + 3x + 30 = 90
4x + 30 = 90
4x = 90 - 30
4x = 60
x = 60/4
x = 15 <===
Answer:
13.
Step-by-step explanation:
Answer:
16/33
Step-by-step explanation:
12C4(total possible outcomes)=495
Since there are 6 married couples there must be 6*[2C2×10C2]=270
must subtracted 15 since when there are 2 couples in a group would have doubled 270-15=255
the no of groupings with no married couples 495-255 =240
probability=no of favourable outcomes /no of possible outcome
probability=240/495= 16/33
Answer:
d. 18
Step-by-step explanation:
3x - 5 = 22
3x = 27
x = 9
Then, 2x is equal to:
= 2(9)
= 18
The answer is 3k+j since 3 cannot be multiplied after k.
