Answer:
x = 5
Step-by-step explanation:
Given
x = ( square both sides )
x² = 3x + 10 ( subtract 3x + 10 from both sides )
x² - 3x - 10 = 0 ← in standard form
(x - 5)(x + 2) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 5 = 0 ⇒ x = 5
x + 2 = 0 ⇒ x = - 2
As a check
Substitute these values into the equation and if both sides are equal then they are solutions.
x = 5
right side = = = 5 = left side ← solution
x = - 2
right side = = = 2 ≠ - 2 ← not a solution
Thus x = 5 is the solution to the equation
The top left graph where the points are descending in a downward fashion best resembles a linear function.
I am at the 55 the same time as a result of the most part
Answer:
I think it it is 5:3:2 = 1kg to 0.6kg to 0.4 kg but I'm not sure so I may not be correct
Step-by-step explanation:
i don't know how to explain
104*.75=78
78/8=9.75(divide by 8 because 80%/8=10%)
9.75*10=97.5
97.5*.8=78
75% of 104 is 78 which is also 80% of 97.5
Your answer is 97.5
