Serggg [28]2 years ago

x( 2 + a ) = bx + 3b

x( 2 + a ) - bx = bx - bx + 3b

x ( 2 + a - b ) = 3b

x ( 2 + a - b ) ÷ ( 2 + a - b ) = 3b ÷ ( 2 + a - b )

x = 3b / 2 + a - b

Answer:

x=3b/(2+a-b)

Step-by-step explanation:

x(2+a)=b(x+3)

2x+ax=bx+3b

2x+ax-bx=3b

x(2+a-b)=3b

x=3b/(2+a-b)

The length of a rectangular garden is 30 yards more than the width. The perimeter is 300 yards. Find the length and width
Delicious77 [7]

Answer:

Length is 90yards and width is 60yards

Step-by-step explanation:

Perimeter= 2( length+width)

let the width be x

then the length will be 30 + x

300 = 2(30+x+x)

150 = 30 + 2x

120= 2x

x = 120/2

x = 60 yards

length= 30+x

= 30 + 60

= 90yards

Write the equation of a line that passes through two points (-1, 0) and (4, -5).
sleet_krkn [62]

Answer:

<u>y = -1 (x) -1</u>

Step-by-step explanation:

If you plug in the numbers from the coordinates into the equation, you will find that it's true.

-1 is x and 0 is y. Plug in the #s like so:

y = -1 (x) -1

0 = -1 (-1) - 1

0 = 1 - 1

0 = 0

Therefore, the equation above represents the line that passes through both these points.
