X= 48 is the correct answer. You can always plug in 48 back into the original equation and make sure it works.
48-23+84+48+23=180
You can cross multiply on this and then solve.
140 / 60 = 200 / x
140x = 12000
x= <span>85.7142857143
x= 85.7</span>
First one I believe. Its been a couple years since I’ve done this so im not 100% sure
the are of parallelogram is A=bh
Events
• A: an even number is rolled in the first time
,
• B: a number greater than 3 is rolled the second time
The probability of rolling an even number is:

The probability of rolling a number greater than 3 is:

Events A and B are independent, then the probability of one happening after the other is:
