Equation 1)  3x + 3y = 12
Equation 2)  x - 5y = 10

First step : 3(x - 5y = 10)

Well, we have to simplify this equation first. *Remember, this is the second equation.

Equation 1)  3x + 3y = 12
Equation 2)  3x - 14y = 30

Well, because both equation 1 & 2 have positive 3x in their equations, we must subtract the equations from one another in order to find the y value.

So, your answer is : C) Subtract the equations.

~Hope I helped!~

Select the correct answer.<br> √3<br> 1,53<br> If the point<br> 3 is on the unit circle, what is x?
emmasim [6.3K]

If the point ( x, √3/ 3) is on the unit circle, then the value of x will be √2/ 3. The correct option is D.

<h3>What is the equation of the circle with radius r units, centered at (x,y)?</h3>

If a circle O has a radius of r units length and it has got its center positioned at (h, k) point of the coordinate plane,

then, its equation is given as:

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

The equation of unit circle is

(x-h)^2 + (y-k)^2 = 1\\\\x^2 + \dfrac{\sqrt{3} }{3}^2 = 1\\\\x^2 + \dfrac{1 }{3} = 1\\\\\\x^2 = 1 - \dfrac{1 }{3} \\\\x^2 = 2/3\\

Thus, x = √2/ 3

If the point ( x, √3/ 3) is on the unit circle, then the value of x will be √2/ 3.

The correct option is D.

one adult ticket for a school play costs 10 dollars and one student ticket costs 6 dollars. one evening,750 people attended the
liraira [26]

The algebraic solution to the situation is as follows:

x + y = 750

10x + 6y = 6860

The number of adult and student are 590 and 160 respectively.

<h3>How to find and solve an algebraic equation?</h3>

One adult ticket for a school play costs 10 dollars and one student ticket costs 6 dollars.

One evening,750 people attended the play and the total receipts were 6860.

Therefore,

let

x = number of adult ticket

y = number of student tickets

Therefore,

x + y = 750

10x + 6y = 6860

10x + 10y = 7500

10x + 6y = 6860

4y = 640

y = 640 / 4

y = 160

Hence,

x  = 750 - y

x = 750 - 160

x = 590
