How do i solve z+18=y
lubasha [3.4K]
<span>Simplifying z + 18 = y Reorder the terms: 18 + z = y Solving 18 + z = y Solving for variable 'z'. Move all terms containing z to the left, all other terms to the right. Add '-18' to each side of the equation. 18 + -18 + z = -18 + y Combine like terms: 18 + -18 = 0 0 + z = -18 + y z = -18 + y Simplifying z = -18 + y</span>

A circular pond is modeled by the equation x^2 + y^2= 225. A bridge over the pond is modeled by a segment of the equation x – 7y
serious [3.7K]
x^2+y^2=225 \\&#10;x-7y=-75 \\ \\&#10;\hbox{solve the second equation for x:} \\&#10;x-7y=-75 \ \ \ |+7y \\&#10;x=7y-75 \\ \\&#10;\hbox{substitute 7y-75 for x in the first equation:} \\&#10;(7y-75)^2+y^2=225 \\&#10;49y^2-1050y+5625+y^2=225 \\&#10;50y^2-1050y+5625=225 \ \ \ \ \ \ \ \ \  |-225 \\&#10;50y^2-1050y+5400=0 \ \ \ \ \ \ \ \ \ \ \ \ |\div 50 \\&#10;y^2-21y+108=0 \\&#10;y^2-9y-12y+108=0 \\&#10;y(y-9)-12(y-9)=0 \\&#10;(y-12)(y-9)=0 \\&#10;y-12=0 \ \lor \ y-9=0 \\&#10;y=12 \ \lor \ y=9

x=7y-75 \\&#10;x=7 \times 12 -75 \ \lor \ x=7 \times 9-75 \\&#10;x=84-75 \ \lor \ x=63-75 \\&#10;x=9 \ \lor \ x=-12 \\ \\&#10;(x,y)=(9,12) \hbox{ or } (x,y)=(-12,9)

-5(v - 1) = -6- (1 + 3v)
dem82 [27]

Answer:

6 =v

Step-by-step explanation:

-5(v - 1) = -6- (1 + 3v)

Distribute

-5v +5 = -6 -1 -3v

Combine like terms

-5v +5 = -7 -3v

Add 5v to each side

-5v+5v +5 = -7 -3v+5v

5 = -7+2v

Add 7 to each side

5+7 = -7+7 +2v

12 = 2v

Divide each side by 2

12/2 = 2v/2

6 =v
