Answer:
13.86
Step-by-step explanation: First- (2.3 * 4/10)
which gives you 27/10
Then (4.16 * 7/1)
Which gives you 11.16/1 (basically 11.16)
Then divide 27/10 which gives you 2.7
add 11.16+2.7
which adds up to 13.86
Answer: 0.0476
Step-by-step explanation:
Given : Two friends and 5 other people compete with each other for first and second chair in an orchestra.
Total people in this competition= 2+5=7
By permutation , Number of ways to arrange 7 people= 7!
Also, number of ways for two friends end up as first and second chair together= 2 × 5! [ 2 ways to arrange friends on first and second chair and 5! ways to arrange others]
I.e. Required probability = 
Hence, the probability that the two friends end up as first and second chair together = 0.0476
The difference of squares is 4m^2 - 20mn + 25n^2
Its a perfect square trinomial.
<h2>What is
perfect square trinomial?</h2>
A perfect square trinomial is the square of a binomial. It follows a pattern when it is factored, so that the first and last terms are perfect squares of monomials and the middle term is twice their product. If the pattern does not fit for a particular trinomial, it is not a perfect square trinomial.
<h3>How to solve this equation?</h3>
(-2m + 5n)^2
(-2m + 5n)(-2m + 5n)
4m^2-10mn-10mn+25n^2
4m^2 - 20mn + 25n^2
Thus, the difference of squares is 4m^2 - 20mn + 25n^2
Its a perfect square trinomial.

X<y
y is 1 more than 2 times the smaler
y=1+2 times x
y=1+2x
3 times y is bigger than 5 times x by 10
3y=5x+10
subsitute
y=1+2x
3(1+2x)=5x+10
3+6x=5x+10
subtract 3 from both sides
6x=5x+7
subtract 5x from both sides
x=7
subsitute
y=1+2x
y=1+2(7)
y=1+14
y=15
x=7
y=15
