Answer:

<h2>Let the number is = X </h2><h2>Two thirds of the number = 2x/3</h2><h2 /><h2>According to the problem given,</h2><h2>x+ 2x/3 = 55</h2><h2>( 3x + 2x ) /3 = 55</h2><h2>5x /3 = 55</h2><h2>x = ( 55 × 3 ) /5</h2><h2>x = 11 × 3</h2><h2>x = 33 </h2>

<h2>Therefore,</h2><h2>Required number = x = 33</h2>

How many solutions can be found for the set of linear equations? Y = 7(x + 2) and y = 7x + 14
Bogdan [553]

Answer:

infinite solution

Step-by-step explanation:

because  Y = 7(x + 2) and y = 7x + 14 are the same

y = 7(x+2) = 7x + 14

eliminate to see

y = 7x + 14

-(y = 7x +14)

= 0 = 0 + 0

so it is infinite solution

The complement of an angle is three times the measurement of the angle. Find the measurement of the larger angle.
olganol [36]
We know that two complements add up to 90.
Let's call the smaller angle x and the larger y.
3x = y
x + y = 90
We can use simple substitution.
x + 3x = 90
4x = 90
x = 22.5

Then, since we know that 3x=y, we can find the larger angle.
3*22.5 = 67.5

Find the center and radius of the circle. Show all work
Alona [7]

The center is (-1, -2) and the radius of the circle is 5.

<h3>What is the equation of a circle?</h3>

The circle equation formula refers to the equation of a circle which represents the center-radius form of the circle.

A circle can be represented as;

\rm (x-h)^2+(y-k)^2=r^2

Where; h and k are the center of the circle r is the radius of the circle.

The given equation of the circle is;

\rm (x+1)^2+(y+2)^2=25

Comparing both the equations;

\rm (x+1)^2+(y+2)^2=25\\\\\rm (x+1)^2+(y+2)^2=5^2\\\\h = -1\\\\k = -2\\\\r^2=5^2\\\\r=5

Hence, the center is (-1, -2) and the radius of the circle is 5.
