Answer:
-5x
Step-by-step explanation:
Remember, if you multiply a negative number by a negative number, you will get a positive number, and positive numbers are greater than negative numbers. In this case, if I were to multiply each of these expressions with -1, I would get the following:
7(-1)+4=-3
-1-4=-5
5(-1)=-5
-5(-1)=5
And I'm sure you can imply how these values will correspond to other negative values. Basically, the last expression gives us a positive answer, which is larger than the others (which give a negative answer).
Answer:
h = 5
Step-by-step explanation:
h/2+1/2=3
Multiply each side by 2 to get rid of the fractions
2(h/2+1/2)=3*2
h+1 = 6
Subtract 1 from each side
h+1-1 = 6-1
h = 5

Step-by-step explanation:
140.7 is the answer in a decimal
Dependent event is an event that is affected by previous events. If you select the first blue gem from three, then the number of blue gems becomes 1 less and when choosing the second blue gem you have to select it from 2 blue gems. So, according to definition these events are dependent.
You have 7 white gems, 5 green gems and 3 blue gems that is 15 in total. Probability to choose first gem blue from jewel case is 3/15=1/5. Then there left 7 white gems, 5 green gems and 2 blue gems that is 14 in total. Probability to choose second gem blue from jewel case is 2/14=1/7.
Use the product rule to count the whole probability: 1/5·1/7=1/35.
