Answer:
u=−x2−x+1
Step-by-step explanation:
Let's solve for u.
2x−u−1x^2−3x+3=2
Step 1: Add x^2 to both sides.
−x2−u−x+3+x2=2+x2
−u−x+3=x2+2
Step 2: Add x to both sides.
−u−x+3+x=x2+2+x
−u+3=x2+x+2
Step 3: Add -3 to both sides.
−u+3+−3=x2+x+2+−3
−u=x2+x−1
Step 4: Divide both sides by -1.
−u/−1=x2+x−1
−1/u=−x2−x+1
Answer:
u=−x2−x+1
Answer:
1/2, 3/6 and 2/4 are equivalent fractions.
Step-by-step explanation:
To know if the fractions are equivalent, their simplest form should be the same.
So we must simplify all the fractions to their simplest form.
To find the simplest form of a fraction, we must divide the numerator and denominator with their GCF (Greatest Common Factor)
So:
1/2 = 1/2
1/3 = 1/3
3/4 = 3/4
3/6 = 1/2 ( The GCF for 3 and 6 is 3)
2/4 = 1/2 ( The GCF for 2 and 4 is 2)
4/10 = 2/5 ( The GCF for 4 and 10 is 2)
Because 1/2, 3/6 and 2/4 has the same simplest form, they are equivalent fractions.
I hope this helps! I'm sorry if it's wrong or too complicated.
Length of the rope = 12 x 5 = 60 m
Length of each divided rope = 60 divided by 3 = 20 m
Therefore, each piece of rope is 20 m long.
To solve this problem we can use equation.
If we assume that x is number of crocodiles, we can say that number of alligators is 4*x because its 4 times more.
We know that together is 40, so we have
x+4*x=40
Now we are reducing.
5x=40 /:5 dividing both sides by 5
x=9 - number of alligators
