The answer is 12 because you put -3 in the C places which gets you 9 – -3 and then you follow the signs which you would have to add them and get 12

What number must multiply each side of the equation 25x=10 to produce the equivalent equation x = 25?
insens350 [35]

Answer:

Multiply both sides by \frac{5}{2}

Step-by-step explanation:

Given

\frac{2}{5}x = 10

Required

Get an equivalent of x = 25

To do this, we simply multiply through by \frac{5}{2}

\frac{5}{2} * \frac{2}{5}x = 10 * \frac{5}{2}

\frac{5*2}{2*5} x = 10 * \frac{5}{2}

\frac{10}{10} x = 10 * \frac{5}{2}

\frac{1}{1} x = 10 * \frac{5}{2}

x = 10 * \frac{5}{2}

x =\frac{10*5}{2}

x =\frac{50}{2}

x = 25

Can you explain it if you could I don’t get it
Vladimir [108]

Step-by-step explanation:

The Triangle Sum Theorem states that the interior angles of a triangle add up to 180 degrees. A square for an angle symbolizes that the angle is 90 °, as is the case with angle ∠ACB.

Therefore, as ∠CAB = 2x and ∠ABC = 3x, and angles ∠ACB, ∠CAB, and ∠ABC make up the interior angles of the triangle, we can say that ∠ACB + ∠CAB + ∠ABC = 180, so 90 + 2x + 3x = 180

90 + 2x + 3x = 180

90 + 5x = 180

subtract 90 from both sides to separate the x and its coefficient

5x = 90

divide both sides by 5 to separate the x

x = 18

(a) ∠CAB = 2x = 18(2) = 36

(b) ∠ABC = 3x = 18(3) = 54

(c) Any triangle with a 90° angle is called a right triangle. This has a 90° triangle, and is therefore a right triangle. Similarly, a 90° angle in a triangle is called a right angle.

Will mark brainiest for simplest and most coherent answer. What does it mean if an x (input) or y (output) value doesn't make se
Maksim231197 [3]

Answer:

I tried to answer but I still would like to know what doesn't make sense.

Considering the identity:

\sec^2\theta-\tan^2\theta=1 \implies |\sec\theta|\geq1

$\forall\;\theta\in\mathbb{R}-\{(2n+1)\frac{\pi}{2}, n\in\mathbb{Z} \}$

The identity is true whenever both sides are defined. It is not supposed to hold the values when we have division by zero, because it is undefined.

If the value doesn't make sense, it is probably not a function, or it is undefined by the given value of x.

Let's go back to the definition of function again:

A function relates a set of inputs and a set of allowable outputs where each input is related to only one output. It basically defines the relation of ordered pairs.

Hope it helped you a bit.
