Answer:
14 =x
Step-by-step explanation:
We can use ratios to solve
5 loaves x loaves
------------- = ---------------
2.5 hours 7 hours
5 * 7 = 2.5 x
Divide by 2.5
35/2.5 = 2.5x/2.5
14 =x
The answer is x=2+5i or 2-5i
Answer:
x = - 1
Step-by-step explanation:
Given
4x = x^2 - 5 Transfer 4x to the right side.
Solution
x^2 - 4x - 5 = 0 Factor
(x - 5)(x + 1)
You want the negative solution. That means that the middle sign must be plus.
x + 1 = 0 Subtract 10 from both sides
x = - 1 Ten on the left disappears by the subtraction process.
Is that correct?
4x = x^2 - 5
x = - 10
4*(-1) = (-1)^2 - 5
-4 = ? 1 - 5
-4 = - 4
and it does work.
24 times 3= 72+4=76+14=90
