Step-by-step explanation:
Answer:
The correct options are,
x = -2 and x = 3
Step-by-step explanation:
It is given that,
x² - x - 6 = 0
<u>To find the solution of given equation</u>
x² - x - 6 = 0 can be written as
x² + 2x - 3x - 6 = 0
x(x + 2) - 3( x + 2) = =
(x + 2)(x - 3) = 0
Either (x + 2) = 0 or (x - 3) = 0
If (x + 2) = 0 then x = -2
If (x - 3) = 0 then x = 3
Therefore the correct options are,
x = -2 and x = 3
X=-2
Move variable to the left and than you divide both sides of equation by 4
SOLUTION:
If you drive at 55 mi/h for 110 miles, this means you drovefor 110 / 55 = 2 hours
Your total driving time is 4 hours and 15 minutes which meansthat you drove 2 and 15 minutes at the rate of 35 mi/h
2 hours and 15 minutes = 2×60 + 15 = 135minutes
35 miles / 60 minutes × ( 135 minutes) = 78.75miles
So total miles driven is 78.75 + 110 =188.75 miles
Answer:
Step-by-step explanation 10 + 2.50d = 850
David starts with $10 and each day he earns $2.50. The d represents a variable and can be any number.
To find d you must solve the equation.
10 + 2.50d = 850
2.50d = 840 (subtract 10 from 850)
d = 336 (divide 840 by 2.50)
It will take David 336 days to save $850.
