Answer:

The original fraction is \frac{2}{5}

Step-by-step explanation:

Let the numerator by X

Denominator is three more than its numerator i.e X +3

When both the numerator and denominator are increased by one the fraction becomes 1/2

\frac{X + 1}{X+3+1} = \frac{1}{2} \\\frac{X+1}{X+4} = \frac{1}{2} \\2X + 2 = X+4\\X = 2

Thus, numerator = 2

Denominator = X +3 = 2+3 = 5

The original fraction is \frac{2}{5}

kari74 [83]

So we need to convert 0.75 feet to inches.

0.75 feet = 9 inches

Then we divide 9 by how many hours are in a day: 24

9/24 = 0.375

The raindrop vine can grow up to 0.375 inches per hour.

How do you do this?????????????

Hey there!

To find the value of an angle in a triangle, you need to add the 3 angles. You have angles with 55 degrees, 65 degrees, and x degrees. Put this into an equation. The equation would be 55+65+x=180. Simplify to get 120+x=180. You need to isolate x, so subtract 120 from both sides to get x=60. So the value of x is 60 degrees.

I hope this helps!

What is Y-3x=-2 and Y+x=-6
love history [14]
Rearranging the first equation gives:

y=3x-2

Substituting this into the other equation gives:

y+x=-6
\\(3x-2)+x=-6
\\4x-2=-6
\\4x=-4 \\x=-1

If x=-1:

y+(-1)=-6
\\y=-5

So x=-1, y=-5
