To solve this one you just need to add all of the minutes each student said, then you can divide them by the total number of students and that would be the mean travel time of students
Answer: 13/25
Step-by-step explanation: Think of 0.52 as fifty-two hundredths which can be written as the fraction 52/100.
Since 52/100 is not in lowest terms, we divide the numerator and the denominator by the greatest common factor of 52 and 100 which is 14 and we get the equivalent fraction 13/25.
Therefore, 0.52 is equivalent to 13/25.
Answer:
6x² + 5x - 2 = 0
Step-by-step explanation:
Given
2x² - 5x - 6 = 0 ← in standard form
with a = 2, b = - 5, c = - 6, then
sum of roots α + β = - =
product of roots = = - 3, then
sum of new roots = +
=
= = -
product of new roots = ×
= = -
Hence the required equation is
x² + x - = 0 or
6x² + 5x - 2 = 0 ( multiplying through by 6 )
Hey there! Welcome to Brainly! I'm happy to help you!
Let's quickly write our equation below.
4(1-x)+2x=-3(x+1)
To solve this, we want to get the x by itself on one side of the equation so we can see what it equals on the other side. First, we need to get it out of the parentheses. To do this, we will use the <em><u>distributive property </u></em>and multiply the number before the parentheses by both terms inside of it as seen below! :)
4(1)-4(x)+2x=-3(x)-3(1)
4-4x+2x=-3x-3
Now, we need to combine our like terms.
4-2x=-3x-3
Now, we want to get all of our constants (numbers without variables) onto the right side. First, we will subtract four from both sides.
-2x=-3x-7
Now, we will add 3x to both sides.
x= -7
I hope that this helps! Have a wonderful day!
