Step-by-step explanation:
2-5/4x=13
- (8x-5)/4x=13
- 8x-5=52x
- -5=52x-8x
- -5=44x
- x=-5/44
-50-15n =g(n-)+
-50. -50
-15n=g(n-)50
-15. -15
N=g(-15n)50
5x - 20y = 60...reduce by dividing by 5
x - 4y = 12
this is the same as the other equation....therefore, it is the same line...meaning infinite solutions
=============
y - 7x = -14
y = 7x - 14.....slope = 7, y int = -14
7y - 49x = -2
7y = 49x - 2
y = 7x - 2/7.....slope is 7, y int is -2/7
if the slopes are the same, but the y int are different, then u have a parallel lines with no solutions
In the word "Mathematical"
Vowels are "a", "e", "a", "i", "a" from left to right
Consonants are "m", "t", "h", "m", "t", "c", "l"
5 vowels and 7 consonants of total 12 letters
So the probability of picking a vowel is

Answer:
∅ = 42°
Step-by-step explanation:
90 - 48 = 42° because 48 and 42 are complimentary angles (add up to 90°)
because the radii lines form an isosceles triangle, ∠∅ also = 42°
