Step-by-step explanation:

the second equation gives us right away

y = 4 - 3x

we can use that now in the 3rd equation :

-2(4 - 3x) + 2z = 4

-8 + 6x + 2z = 4

6x + 2z = 12

3x + z = 6

z = 6 - 3x

now we use both in the 1st equation :

-2x + 3(4 - 3x) - (6 - 3x) = -2

-2x + 12 - 9x - 6 + 3x = -2

-8x + 6 = -2

-8x = -8

x = 1

y = 4 - 3x = 4 - 3×1 = 4 - 3 = 1

z = 6 - 3x = 6 - 3×1 = 6 - 3 = 3

so,

Answer:

No solution

Step-by-step explanation:

On the left side we have one half x plus one half x  which equals x.  On the right side we have x + 1.  So the equation becomes x = x + 1.  Subtracting x from both sides we get 0 = 1, which is false.  Therefore there is no solution to this problem.  

Step-by-step explanation:

THE POINT OF INTERSECTION IS WHERE F(x) = G(x)

[tex](x + 3)(x - 1) = (x + 1)(x - 3) \\ {x}^{2} + 2x - 3 = {x}^{2} - 2x - 3 \\ \\ {x}^{2} - {x}^{2} + 2x + 2x - 3 + 3 = 0 \\ 4x = 0 \\ \frac{4x}{4} = \frac{0}{4} \\ x = 0[/tex]

find the y coordinate by plugging in the value of c in any of the function.You will get thw same value

[tex]g(0) = (0 + 1)(0 - 3) \\ g(0) = 1( - 3) \\ g(0) = y = - 3[/tex]

The point of intersection is (0,-3)

Using proportions, it is found that Kurt spent $22.68 a month on movie streaming services.

A proportion is a fraction of a total amount, and equations can be built to find the desired measures in the problem using a rule of three, or operations such as multiplication and division.

These operations are used from the unit rates, as for example, when we have an amount over a period of time, the amount per unit of time is the total amount divided by the total time.

For this problem, we have that the important parameters are found as follows:

Hence his monthly spending is given by the unit rate as follows:

Using the ratio given in the question,

The relation between the quantities of two or more objects—referred to as a ratio—indicates how much of one object is contained in the other. The ratio formula can be used to represent a ratio as a fraction. The ratio formula is given as, for any two quantities, let's assume a and b.

a:b = a/b

Given that James, Fay and Sal share 160 apples.

Total number of apples =  160

Hence, apples received by James = 1/4(160)

= 40 apples

Remaining apples = 160 - 40 = 120 apples

It is also given that the remainder is shared by Fay and Sal in the ratio 3:2.

Hence, the total share will be 3+2=5

So, we can write that Fay's share will be 3/5 of total apples and Sal's share will be 2/5 of the total apples.

Fay's share = 3/5(120)

=3(24)

=72 apples

Sal's share = 2/5(120)

=2(24)

=48 apples

Therefore, the number of apples with Fay is 72.

The number of apples with Sal is 48.

The speed of the plane and wind in km/hr is 187.5 and 37.5 respectively.

A linear equation has highest degree of 1.

According to the given question a small plane flies for 3 hours to an airport 450 kilo meters away against a strong headwind. the plane then returns to its starting location flying with the wind, taking 2 hours.

Form these we can form two linear equations in two variables.

Assuming speed of the plane to be x km/hr and speed of wind to be y km/hr.

We know Distance = speed × time.

3( x - y) = 450. and 2( x + y) = 450.

3x - 3y = 450...(i) and 2x + 2y = 450...(ii)

multiplying eqn (i) by 2 and eqn (ii) by 3 and solving we get

Answer:

Choice 1: ∠CFG = ∠FCB

Step-by-step explanation:

∠CFG and  ∠FCB are interior alternate angles and equal only if ABCD||EFG

The equation that represents the line that passes through the point (6, −3) and has a slope of one half is 2y - x = 13.

The equation of a line is represented as,

y = mx + c                                       equation1

x and y are the coordinates of the point from where the line is passing and m is the slope of the line.

As per the question the line is passing from the point (6, -3). This means value of x = 6 and that of y = -3. The slope of line is (1/2), means m = (1/2).

The slope of the line through the point (-1,6) can also be written as   (y - 6)/(x - (-1))  =  (y-6)/(x+1).

i.e., m = (y-6)/(x+1)

On equating both the values of m, we will get

(y-6)/(x+1) = 1/2

On simplifying, we get

2y - 12 = x +1

or  2y - x = 13

The equation that represents the line that passes through the point (6, −3) and has a slope of one half is 2y - x = 13.

Answer:

x =52

Step-by-step explanation:

The angles shown are same side interior angles, and when the lines are parallel, same side interior angles add to 180 degrees

< 1 + <2 = 180

x+23    + x+53   = 180

Combine like terms

2x+ 76 = 180

Subtract 76 from each side

2x+76-76 = 180 -76

2x = 104

Divide by 2

2x/2 = 104/2

x =52

Answer:

x = 52

Step-by-step explanation:

Angle 1 and angle 2 are on the same side, and on the inside of the interior. This means that when added together they = 180

We can set up an equation

x+23+x+53 = 180

Simplify: 2x + 76 = 180

Subtract 76 from both sides

2x = 104

Now divide by 2

x = 52
