Answer:
x=62
Step-by-step explanation:
1. add + 25 to both sides because when you have a negative you have to add.
2. When you add 25 to 37 you get 62.
therefore 62 is the answer
I think none of these are right. It's Y=-5/3x +4/3
Answer:
Step-by-step explanation:
Flipping a coin and rolling a number cube are both independent events. Independent events do not rely on the outcome of any previous events. This means that whatever you flip on the coin will have no effect on whatever you roll on the number cube and each flip of the coin or roll of the cube has the same probability as the flip or roll before.
The probability of getting tails on a coin toss is:
The probability of getting a number less than 3 (so 1 or 2) on a number cube is:
Since we are combining these events, we need to multiply the fractions together to get our overall probability:
*=
Answer: 10√3 / 3
Step-by-step explanation:
cos 30 = 5 / x
x = 5 / cos 30
= 5 / √3 / 2
= 10 √3
= 10√3 / 3
