Answer:
x=11/2
Step-by-step explanation:
1/2x-4=7+1/6x
1/2x-1/6x=7+4
6*1/2x-1/6*6=11 As 6 is the Lcm and we have to multiply it to the fractions.
3x-x=11 As 6 divided by 2 is 3 and 3 multiplied by x is 3x.
2x=11
x=11/2 OR 5 1/2
Given: <span>y = x^2 + 6x - 5. Then a = 1, b = 6 and c = -5.
The x-coord. of the vertex is given by x = -b / (2a), which here is x = -6 / (2*1) = -3.
Use the given formula </span><span>y = x^2 + 6x - 5 to find the value of y when x = -3:
y = (-3)^2 + 6(-3) - 5 = 9 - 18 - 5 = -14
Then the vertex is (-3, -14).</span>
Answer:
x = 20
Step-by-step explanation:
Each side would be 60. 60/3 would be 20. So x = 20
Answer:1 thousandth
Step-by-step explanation:
There is a total of 24 students in the class.
The probability of choosing a girl is 16/24. Which reduces down to 2/3 or 66%.
The probability of choosing a boy is 8/24. Which reduces to 1/3 or 33%.
So the student has a 66% chance of choosing a girl and 33% chance for a boy.
