Answer: Combine like terms!
Step-by-step explanation:
-4x + 3x = 2
-1x = 2
-1x/-1 = 2/-1
x = -2
equal to 35/3 that is 7*5/3 and finally equal to 11.666
Answer:
P( At least one of the two cards was a heart)=7/16
Step-by-step explanation:
The solution to this question can be found in two ways.
First way: Since total number of heart in a deck are four,
Probability that neither of two cards had a heart is that at both times the card drawn was not a heart, since it is an independent event, thus probability both were not heart=
×
=
Thus, Probability that at least one of the two cards was a heart= 1- P( Neither of two cards had a heart= 1- 
=
Second way:
Probability that first card drawn is a heart and the second one is not a heart=
×
=
Probability that the first card drawn is not a heart and the second one is a heart=
×
=
Probability that both cards drawn are hearts=
×
=
Adding all these probabilities, we have the probability that at least one of the card drawn was heart= 
Answer:
8900
Step-by-step explanation:
25 * 89 /
= 25 * 89 * 4 = 100 * 89 = 8900
It can be called a "percentage."
10/100 of a whole is 10% of it.
