Step-by-step explanation:
There are 60 minutes in 1 hour
To express as a fraction
Divide numerator/denominator by 15
=
The hundred thousands place is the 2. Since the place below that is 0, it rounds down.
200,000
Answer:
x5y2−x2y4
Step-by-step explanation:
There are no like terms. Therefore the answer is correct. =x^5y^2−x^2y^4
Answer:
Convert to a simplified fraction.
1/169
Step-by-step explanation:
i think this is right im not sure <em>IM SO SORRY IF THIS IS THE WRONG ANSWER</em>
I would love to use substitution (It is simplier that way I guess)
solve your system of equations.
x+2y=−1;x−y=5
Solve x+2y=−1 for x:
x+2y+−2y=−1+−2y(Add -2y to both sides)
x=−2y−1
Substitute (−2y−1) for x in x−y=5:
x−y=5
−2y−1−y=5
−3y−1=5(Simplify both sides of the equation)
−3y−1+1=5+1(Add 1 to both sides)
−3y=6
−3y/−3 = 6/−3(Divide both sides by -3)
y=−2
Substitute (−2) for y in x=−2y−1:
x=−2y−1
x=(−2)(−2)−1
x=3(Simplify both sides of the equation)
So the answer is (x = 3 and y = -2)
