Group and factor/undistribute
(x^2y^3-2y^3)+(-2x^2+4)
(y^3)(x^2-2)+(-2)(x^2-2)
see the (x^2-2) is common term so undistribute
(x^2-2)(y^2-2)
last one
W=t times 8 :)
When you are solving the equation you see that after 9 minutes there is 72 inches to find the unit rate you divide 9 by 72 and you get 8 so per each minute there is 8 inches of water
Answer:
-1/2
Step-by-step explanation:
2(5y + 3) + 4y = -1
2*5y + 2*3 + 4y = -1
10y + 6 + 4y = - 1 {Combine like terms}
14y + 6 = -1 {Subtract 6 form both sides}
14y = -1 - 6
14y = -7 {Divide both sides by 7}
y = -7/14
y = -1/2
Answer:
Step-by-step explanation:
no of yellow golf=1/7*28
=28/7
=4
no of white golf=5/7*28
=140/7
=20
no of green golf=total golf-(yellow golf + white golf)
=28-(4+20)
=28-24
=4
therefore he has 4 green balls
