Answer:
x < -7
Step-by-step explanation:
3x < -21
<u>Step 1: Divide both sides by 3</u>
3x < -21
3x / 3 < -21 / 3
x < -7
Answer: x < -7
Answer:
Step-by-step explanation:
Keep the variables in the left side & rest in the left side:
There are 4 choose 3 ways to hold 3 kings and 4 possible queens to make up the fourth card of the hand out of a total of 54 choose 4 possible four-card hands, which gives us the following expression for the probability of being dealt 3 kings and a queen out of 4 cards: Or roughly 1 in every 16920 four card hands.
Answer:
sin A = 13/85
Step-by-step explanation:
Opposite Angle A is side BC, of length 13. The length of the hypotenuse is 85. The sine function is defined as the ratio opp/hyp. In this problem that ratio is
opp
------ = sin A = 13/85
hyp
We use the inverse sine function arcsin x to determine Angle A:
A = arcsin 13/85 = 8.8 degrees
