Answer:

x=7.5

Step-by-step explanation:

step 1: do distribute property to the equation.Multiply 3 by everything inside the parenthesis

3(x+4.5)=36

3x+13.5=36

step 2: subtract 13.5 by it self to cancel out and by 36

3x+13.5=36

    -13.5  -13.5

--------------------

3x=22.5

step 3: divide by 3

3x=22.5

x=7.5

step 4:Substitue x into the equation

3(7.5+4.5)=36

<em>3(12)=36</em>

What value of y makes the 2 triangles congruent by SSS?
aleksandrvk [35]
The triangle was just flipped so the missing side is going to equal 36, so...
2y+20= 36
(Subtract 20 from each side to isolate the 2y)
2y= 16
(Divide each side by 2 to isolate the variable)

ANSWER:
y= 8

1 For each line
Elena-2011 [213]

Step-by-step explanation:

I'll do line A for you and you can use the formulas to solve lines B and C yourself, since its good for you to practice doing these questions yourself

a)

The gradient, m, is calculated using m = (y2-y1)/(x2-x1) where x1,x2,y1 and y2 can be any ordered pairs on the line.  I'm going to use (4,0) and (7,3) as the 2 points.

m = (3-0)/(7-4) = 3/3 = 1

b)

The y-intercept is where the line intersects with the x-axis. In this case (0,-4)

c)

The equation of a linear line is y=mx+b (or c depending on which country you are from)

y = 1x-4

y=x-4

Now try the other 2 lines yourself!
