Answer:
x = √(28), or x = 5.292
Step-by-step explanation:
First you distribute the square to the values inside of the parentheses. so it ends up looking like this
5(x^2 - 25) - 9 = 6
add 9 to both sides
so its 5(x^2 - 25) = 15
Then distribute the multiplication of 5 to the contents within the parentheses
so it would be 5x^2 - 125 = 15
add 125 to both sides
you get 5x^2 = 140
divide by 5 on both sides
you get x^2=28
then, take the square root of both sides to reverse the square
√(x^2)=√(28)
and in the end you get x=5.292
but √(28) will probably be fine if your teacher doesn't want u to solve for that kind of stuff.
1) 15/15 which is 1
2)100/30 which is 3 1/3
3)8.2
4) too long sorry
You have to show a picture so we can solve this problem you’re having.
Answer:
B
Step-by-step explanation:
1/2x - 2 > 0
collect like terms
1/2x > 0 + 2
1/2x > 2
Divide both sides by 1/2
x > 2 divided by 1/2
inverse of 1/2 is 2/1
x > 2 times 2/1
x > 4
The probability is the probality of being designated a a management trainee (i.e. 30%) * the probability of not be appointed to a management posittion (i.e. 25%, which comes from 20% to be assigned to nonmanagerial position + 5% of being fired).
Result: 30% * 25% = 7.5%.
Answer: 7.5%.
