defon3 years ago
3 0

Answer:

1/3

Step-by-step explanation:

3(x-1)-2(2x+1)=8(x-1)

3x-3-4x-2=8x-8

3x-4x-3-2=8x-8

-x-5=8x-8

-x-8x-5=-8

-9x-5=-8

-9x=-8+5

-9x=-3

9x=3

x=3/9

simplify

x=1/3

If BAC = 320°, what is the measure of BC?
melisa1 [442]

Answer:

BC = 40º

BMC = 40º

Step-by-step explanation: Since the measure the major and minor arcs add up to 360º, just subtract 320 from 360 to find BC which is 40º. <BMC is also 40º because the measure of the arc is equal to its corresponding angle.

Polygon ABCD is a rectangle what is the area
Andre45 [30]

Solution:

As, You have Written Polygon ABCD is a rectangle.

It is a Four sided Polygon , having all it's interior angles equal to 90°.As well as Opposite sides are equal(AB=CD,AD=BC), equal diagonals(AC=B D).

Join any of the diagonal of Rectangle either AC or B D.

In Right Δ ABC , Right angled at B

{\text{Area (Right triangle ABC)}} =\frac{1}{2}\times AB \times BC---(1)

In Right  Δ ADC  , Right angled at D      

{\text{Area (Right triangle ABC)}} =\frac{1}{2}\times AD \times DC---(2)

Adding (1) and (2) that is LHS to LHS and RHS to RHS

Ar( Δ ABC) +Ar( Δ ADC)=\frac{1}{2}\times[ AB \times BC+ AD \times DC]\\\\=\frac{1}{2}[2 \times AB \times BC][\text{As, AB=CD, and BC=AD}]\\\\ = AB \times BC

So, Area of Rectangle= Product of any two Adjacent Sides

X+2y=-1 and 4x-4y=20 solve by substitution
Illusion [34]

To do this problem you would first need to factor out a variable, which in this case I would want to do the first equation because it is isolated. Now the equations would look like this:

x = -2y - 1

4x - 4y = 20

Since we know that x is now equal to -2y - 1 we can plug it in to the x value in the second equation:

4 (-2y -1) - 4y = 20

-8y -4 - 4y

-12y - 4 = 20

-12y = 24

y = -2

Now that we know the y value plug the y value to one equation to find the x, I will be using the first equation

x + 2(-2) = -1

x - 4 = -1

x = 3

Solutions:

y = -2

x = 3
