Answer:

104

Step-by-step explanation:

The ratio of boys : girls = 3 : 1 = 3x : x ( x is a multiplier )

There are 52 more boys than girls , so

3x = x + 52 ( subtract x from both sides )

2x = 52 ( divide both sides by 2 )

x = 26, then

3x = 3 × 26 = 78 ← number of boys

Total number = 78 + 26 = 104

What is the final elevation if a bird starts at 20 m and changes 16 m?

charle [14.2K]

Answer:

36 meters

Step-by-step explanation:

The bird starts at 20 and (assuming it goes up) increases by 16 meters. You have to add to get 36. However, if the bird flies 16 meters down, the answer would be four meters. The answer 36 is assuming the bird flies upward.

consider the equation is Y equals 1/square root of x and y=x-2. approximate solution of the system equations

emmasim [6.3K]

Answer:

$x=1$ and $x=4$

Step-by-step explanation:

We have the following system of equations:

$y=\sqrt{x}$ and $y=x-2$

To solve the problem, we need to equal the two equations:

$x-2=\sqrt{x}$ ⇒ $(x-2)^{2} =x$ ⇒ $x^{2} -4x + 4 = x$

⇒ $x^{2} -5x + 4 = 0$

So you need to find two numbers that added equal to 5 and multiplied equal to 4. These two numbers are $x=-1$ and $x=-4$ .

Then, the factorized form of the polynomial is: $(x-1)(x-4)$ .

The, the solution to the system of equations is: $x=1$ and $x=4$ .
