Answer:
6
Step-by-step explanation:
Unknown number = x
So,
x - 4 = 2 (add 4 to both sides)
x - 4 + 4 = 2 + 4
x = 6
Answer:
3 / 248
Step-by-step explanation:
Draw 1:
Favourable Outcome / Total number of possible outcomes
=> 4/32
=> 1/8 chance for first draw
Draw 2:
Favourable Outcome / Total number of possible outcomes
=> 3/31 Chance of green for second draw
To find the chance of getting 2 greens at consecutive draws = 1/8 x 3/31
= 3/248
The probability of rolling an even number first and an odd number second is 1/4.
<h3>What is the probability?</h3>
Probability determines the chances that an event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.
The probability of rolling an even number first and an odd number second = (numbers that have the even number first and odd number second / total sample space)
9/36 = 1/4
Here is the complete question:

The answer is -30-25 which in turn becomes -55
Answer:
4
Step-by-step explanation:
3x + 2(x + 4) + 2x+1 = 37 Remove the brackets.
3x + 2x + 8 + 2x + 1 = 37 Collect like terms
7x + 9 = 37 Subtract 9 from both sides
7x + 9-9 = 37 - 9 Combine
7x = 28 Divide by 7
7x / 7 = 28/7
x = 4
