Answer:

51°

Step-by-step explanation:

Note that the square in the angle place = 90°.

Also note, that a complete circle is 360°.

Set the equation. Let the ? be denoted by the variable x:

x + 90+ 124 + 95 = 360

Simplify. Combine like terms:

x + (90 + 124 + 95) = 360

x + (309) = 360

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Subtract 309 from both sides of the equation:

x + 309 (-309) = 360 (-309)

x = 360 - 309

x = 51

51° is your answer.

Solve for x.<br>8 + 6x<br>4*+2

zheka24 [161]

Answer:

x = 0

Step-by-step explanation:

8 + 6x = 4 * 2

If this is the equation then start with multiplying 4 by two and subtracting 8 from both sides

6x = 0

Divide 6 from both sides

x = 0

To test this, insert the value of x which is 0

8 + 6(0) = 4 * 2

Multiply 6 and 0

8 + 0 = 4 * 2

Multiply 4 and 2

8 + 0 = 8

Add

8 = 8

This equation is true as you can see so x is equal to 0.

Hope this helps.

A retail chain will buy 900 cordless phones if the price is $40 each and 700 if the price is $60. a wholesaler will supply 550 p

Triss [41]

Answer:

The point of equilibrium is (40,900).

Step-by-step explanation:

It is given that the supply and demand functions are linear.

From the given information it is noticed that the demand function passing through the points (40,900) and (60,700). The supply function passing through the points (30,550) and (50,1250).

If a line passing through two points, then the equation of line is

$y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)$

The demand function is

$y-900=\frac{700-900}{60-40}(x-40)$

$y-900=-10(x-40)$

$y-900=-10x+400$

$y=-10x+1300$ .... (1)

The demand function is $y=-10x+1300$ .

The supply function is

$y-550=\frac{1250-550}{50-30}(x-30)$

$y-550=35(x-30)$

$y-550=35x-1050$

$y=35x-500$ .... (2)

The supply function is $y=35x-500$ .

Equilibrium is the point where the demand and supply are equal.

On solving (1) and (2), we get

$x=40$

$y=900$

Therefore the point of equilibrium is (40,900). It means the retailer can buy 900 phones for $40 each and the wholesaler can sale 900 phones for $40.
