Answer:
The final answers are x = 10.385 OR x = -0.385
Step-by-step explanation:
Given the equation is x^2 -4 = 10x
Rewriting it in quadratic form as:- x^2 -10x -4 = 0.
a = 1, b = -10, c = -4.
Using Quadratic formula as follows:- x = ( -b ± √(b² -4ac) ) / (2a)
x = ( 10 ± √(100 -4*1*-4) ) / (2*1)
x = ( 10 ± √(100 +16) ) / (2)
x = ( 10 ± √(116) ) / (2)
x = ( 10 ± 10.77 ) / (2)
x = ( 10 + 10.77 ) / (2) OR x = ( 10 - 10.77 ) / (2)
x = 20.77/2 OR x = -0.77/2
x = 10.385 OR x = -0.385
Hence, final answers are x = 10.385 OR x = -0.385
Answer:unpredictable
Step-by-step explanation:
Answer : The total number of fossils at the museum are, 25
Step-by-step explanation :
As we are given that 60% of a museum’s fossils are from the Jurassic Period.
Let the total number of fossils at the museum be, 'x'
Given:
Number of fossils from the Jurassic period = 15
The % of a museum’s fossils are from the Jurassic Period = 60%
Thus, the expression will be:

By solving the term 'x' we get:


Thus, the total number of fossils at the museum are, 25
