Hello,
Assume x the smallest side.
y the third side
z the largest side
z=2x-4
y=10+x
x+y+z=86
==>x+(10+x)+(2x-4)=86
==>4x=86-10+4
==>x=20, y=30 and z=36
x= 49/9 − 2y/9
Step-by-step explanation:
Move all terms that dont contain x to the right side and solve. (I solved for x i hope thats what you needed. Next time be a little more detailed. (: )
4x - 2 > 12
4x > 10
X > 5/2

Step-by-step explanation:
As all the questions of the exam carry 2 points, at least
questions need to be correct to get 56 marks.
In order to get a maximum of 56 marks, at most 28 answers needs to be correct.
Every question has two option. Hence, the probability of getting a particular question right is
.
The probability that exactly n questions will be right is
.
The probability that at most 28 questions will be right is ∑

.
Similarly, the probability that at least 30 questions will be right is ∑
