Answer:
Alyssa's team won 20 games.
Step-by-step explanation:
We can introduce a variable that represents how many games Alyssa's team won.
Let x<em> </em>represent how many games Alyssa's team won.
We can now create a expression, we know that her team won 5 out of 7 games which would be equivalent to the fraction 5/7. We also know her team has played 28 games and five sevenths (5/7) of those they won.
This would give us the expression 5/7 = x/28.
We need to do this because 5/7 is equivalent to x the numbers of games they won over 28 the number of games they played.
Solving for 5/7 = x/28 we have:
5/7 = x/28
We need to isolate x on the right side to do so we can multiply both sides by 28.
5/7 * 28 = x/28*28 simplifying
20 = x.
Therefore the number of games Alyssa's team won is 20 games.
X = -(-1) +/- sqrt((-1)^2 - 4*4*3)
------------------------------------ = 1/8 +/- sqrt47i
2 * 4
None of the choices are correct
Considering that 12 inches are in 1 foot, 179/12 = 14, remainder 11. Therefore the answer is 14 feet and 11 inches
Sam can his job in 20 min. So he can do the whole job at the rate of 1 job in 20 minutes.
So he does 1/20 of the job per minute.
Rob can do the job in 30 min. His rate is 1/30 of the job per minute.
.
Working together how long does it take?
.
1/20*x + 1/30*x = 1 job done
, where x = minutes.
Multiply everything by 60 to get rid of the fractions.
3x + 2x = 60
5x = 60
.
Divide both sides by 12
x = 12
.
So the answer for working together it will take them 12 minutes.
