I’m assuming you man degrees? Are these angles of a triangle?
This doesn’t really make sense because the angles in a triangle add up to 180° so your equation would be x+50+x+80+72=180
Combine like terms to get
2x+202=180
Then subtract 202 from both sides
2x=-22
So x would be -11 which doesn’t seem right lol
5x5x4x7x6 is equal to 4,200
I wouldn’t change anything because that is how I lived my life
Answer:
c)21
Step-by-step explanation:
"To light a park, luminaries are placed along a length of 100 meters, if the first is placed in meter 1, the next in meter 4, the next in meter 7, and so on. in the following positions a luminary will be placed except in the subway:
a)13 b)19 c) 21 d)28? "
-------------
Luminaries position:
It makes an AP with the first term of 1 and common difference of 3
The formula for this AP is:
- aₙ = 1 + 3(n-1) = 1 + 3n - 3 = 3n - 2
From the given options, only one is not in the same format:
because
- 21 = 3n - 2 ⇒ 3n = 23 and n= 23/3 is not an integer
Answer is: c) 13
Answer:
Infinately many solutions.
Step-by-step explanation:
2x-4=2(x-2)
Distribute
2x-4=2*x-2*2
2x-4=2x-4
Since both sides are the same, there are infinately many solutions.
Hope this helps!
