Answer:

I think the answer would be A) If two angles are equal in a triangle, then the sides opposite are equal.

Step-by-step explanation:

I hope this helps, have a nice day :]

AB = BC

AC is the opposite side of ∠2.

BC is the opposite side of ∠1.

Opposite sides of equal angles are equal.

It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.

We have,

∠3 = ∠1

From the figure, we see that,

∠3 and ∠2 are vertical angles.

Vertical angles are equal.

Now,

∠2 = ∠1

AC is the side opposite to ∠2.

BC is the side opposite to ∠1.

The sides that are opposite to equal angles are also equal.

Thus,

AC and BC are equal.

Answer:

Yes, x = 33 is a solution

Step-by-step explanation:

To see if it is a solution, plug in 33 as x

3 = x/11

3 = 33/11

3 = 3

Since this is correct, x = 33 is a solution.

Given,

The value of x is 33.

[tex] \implies \: 3 = \bf\dfrac{x}{11} [/tex]

[tex] \implies \: 3 \times 11 = \bf x[/tex]

Putting the value of x ..

[tex] \implies \: 33 = 33[/tex]

Left hand side is equal to right hand side, it means that x = 33 is a solution of given equation.

Answer:

d + c = 12

d = 2c - 3

Step-by-step explanation:

Given that :

Total number of dogs and cats = 12

Let :

Dogs = d ; Cats = c

d + c = 12

Number of dogs = 2 times the number of cats less than 3 ;

Mathematically,

d = 2c - 3

The system of equations to model the situations are,

d + c = 12 and d = 2c - 3.

System of equations are a set of two or more equations which has to be solved together, which means the solution we get after solving these equations must be satisfying for all the equations given.

System of equations will get a unique solution if the number of variables in the equation is equal to the number of equations in the system.

Let 'c' denote the number of cats and 'd' denote the number of dogs.

Total number of dogs and cats = 12

That is, d + c = 12

Number of dogs is 3 less than twice the number of cats.

So, d = 2c - 3

Hence the system of equations to model the given statements is,

d + c = 12

d = 2c - 3

Answer:

The equation of the line  that contains the point (4,3) and is perpendicular to the line represented by the equation y=2/5x+3 will be:

Step-by-step explanation:

The slope-intercept form of the line equation

y = mx+b

where

Given the line

y=2/5x+3

comparing with the  slope-intercept form of the line equation

Thus, the slope of the line is: m = 2/5

We know that a line perpendicular to another line contains a slope that is the negative reciprocal of the slope of the other line, such as:  

slope = m = 2/5

Thus, the slope of the the new perpendicular line = – 1/m = [-1]/[2/5] = -5/2

Using the point-slope form of the line equation

[tex]y-y_1=m\left(x-x_1\right)[/tex]

substituting the slope of perpendicular line m = -5/2 and the point (4, 3)

[tex]y-3=-\frac{5}{2}\left(x-4\right)[/tex]

Add 3 to both sides

[tex]y-3+3=-\frac{5}{2}\left(x-4\right)+3[/tex]

[tex]y=-\frac{5}{2}x+13[/tex]

Therefore, the equation of the line  that contains the point (4,3) and is perpendicular to the line represented by the equation y=2/5x+3 will be:

Answer:

41%

Step-by-step explanation:

First, we have to find what percent is dirty, so our equation is:

118/200 = 59/100 = 59%

Then we have to find how much of 100% is left after we take away 59%:

100 - 59 = 41

So 41% of the plates are clean
