Answer:

Yes, all three of them are proportional

Step-by-step explanation:

First, let's simplify them all the way:

10/45 = 2/9

20/90 = 2/9

6/27 = 2/9

All three of these ratios simplified down to their simplest form are 2/9, meaning that they are all proportional.

Answer:

the measure of AB equals the measure of BC

2x+1=3x-4

4+1=3x-2x

5=x

BC=3x-4=3*5-4=15-4=11

AB=2x+1=2*5+1=10+1=11

AC=AB+BC=11+11=22

9. 1/3+(x+20)+(x-10)+40=360 10. 1/2x+1/2x+(x-15)+(x-25)+100=540

1/3+2x+50=360 4x+60=540

(3/1) 1/3+2x=300(3/1) 4x/4=480/4

Solving systems of two linear equations by adding the equations together is called

Anarel [89]

Addition elimination.

This method is used to eliminate one of the two variables in the equations. This makes it easier to solve for the remaining variable.

The square below has area 100. Find the area of the shaded region.

Degger [83]

Answer:

21.46

Step-by-step explanation:

Start with the square

$A = a^{2} \\100 = a^{2}\\10 = a$

Each side of the square is 10

This also means the diameter of the circle is 10, with a radius of 5

$A = \pi r^{2} \\A = \pi 5^{2} \\A = 78.54$

Now substract the area of the circle from the square

x = 100 - 78.54
