2-8x+12=5(x-7)
-8x+14=5x-35
-8x-5x=-35-14
-13x=-49
x=-49/-13=49/13
Solution : x=49/13
The value of N is 289.
Step-by-step explanation:
A sequence of number is given with a missing number "N".
To find N, find which pattern is followed in the sequence:
The sequence goes on reducing with small number than the previous one.
so, finding the difference= 400-361= 39
361-324= 37
It is found that 39-37= 2.
37-2= 35 and follows as 33 and 31.
So, the next number N can be find by 324-N= 35
324-35= N
N= 289
check whether the next number is followed correctly or not,
289-256 must give 33 and 256-225 gives 31. <u>So the N value is correct.</u>
Answer:27/220
Step-by-step explanation:
She must have 2 �1 coins and 1 50p coin.
She can choose the 2 �1 coins 3C2 = 3 ways.
For each of those 3 ways she can choose the
50p coin 9C1 or 9 ways.
That's 3�9=27 ways to get �2.50.
She can choose any 3 coins in 12C3 = 220 ways.
The desired probability is 27 ways out of
220 ways,or 27/220, or 13.5% of the time.
He should increase the length and width by a factor = sqrt 3.
so new length should be 78* sqrt3 = 135.1 - that is increase of 58.1 ft
and new width should be 65 * sqrt3 = 112,58 = increase of 47.58 ft
The right one is the 31? I think I’m guessing
