Answer:

156 degrees

Step-by-step explanation:

Bisects meand to cut into two equal halves.

That means 4x-2=3x+18.

Subtracting 3x on both sides gives x-2=18

Adding 2 on both sides gives x=20

If x=20, then 4x-2 equals 4(20)-2=78.

The other half is also 78 since the two angles were comgruent.

The whole angle is 78+78=156.

Bags of sugar come in 3 sizes:
Mrrafil [7]

Answer:

Medium

Step-by-step explanation:

The computation is shown below:

The cost for the small and medium bag is shown below:

As we know that

1kg = 1000g

So 3kg = 3000g

Now for small bags

= 0.95 ÷ 250 × 3000

= £11.40

For medium bags

= £1.80 ÷ 500 × 3000

= £10.80

So here the medium bag would represent the better value

Area of a circle is:

A = πr²

We are given a radius of 20 cm.

A = πr²

A = π(20)²

A = π400

<em>A = 400πcm²</em>

Hope this helps.

Look at the picture. What is the solution WORTH 10 POINTS
Ivanshal [37]

The coordinates of the point intersection of lines (-1, -1)

If you want solve:

y = -2x - 3, y = 3x + 2

-2x - 3 = 3x + 2     |+3

-2x = 3x + 5     |-3x

-5x = 5     |:(-5)

x = -1

Put the value of x to the first equation:

y = (-2)(-1) - 3 = 2 - 3 = -1

x = -1, y = -1

zzz [600]

Answer:

1/8

Step-by-step explanation:

<u>Solving in steps:</u>

  • x(8x - 8y)⁻¹ + y(8y - 8x)⁻¹ =
  • x/8(x-y) +y/8*(-(x-y))
  • x/8(x-y) - y/8(x-y) =
  • (x -y)/8(x-y) =
  • 1/8

Answer is 1/8
