Answer:
This will be 12/20
Step-by-step explanation:
You take the number of favourable outcomes (12, as there are 12 boys) and take the number of total outcomes (20, as there are 20 people in total). Then you do the number of favourable outcomes over the number of total outcomes. This equals 12/20. I hope this helps
Answer:
-5x^5 + 2x^3 - 6x should be your answer
3/ (2/3) =
3/1*3/2=9/2
Therefore the answer is 9/2
Answer:
Profit earned by Randi on her last snow shoveling and salting job= $ 60
Let number of hours spent by Randi on that day while working as a shoveler and salter = x hours
Writing the statement in terms of inequality
→ Number of hours worked= Amount of profit earned
→ x=60
→If profit is less than $60.00, then Number of hours will be less.
→If Profit is more i.e greater than $60.00, Number of hours will be more.
Answer:
Step-by-step explanation:
It seems to me that you are being asked for what values of x does f(x) + g(x) = 0. Which means that you need to add them together, combine like terms if possible, and then factor. Adding them together gives you
This doesn't factor to integer solutions, so we will use the quadratic formula to factor it. The quadratic formula is as follows:
For us, a = 1, b = 6, c = 4. Filling in accordingly:
and simplifying a bit:
The square root of 20 can be simplified down to 2√5, so plugging that in gives us:
and then reducing everything down to its lowest terms:
x = -3 ± √5. Those are irrational numbers but they are the numbers that make that addition o to 0.
