three times a number,minus 2, is equal to two times the number,plus 7​

Answers

Answer 1

Answer:

9

Step-by-step explanation:

3x−2=2x+7

Step 1: Subtract 2x from both sides.

3x−2−2x=2x+7−2x

x−2=7

Step 2: Add 2 to both sides.

x−2+2=7+2

Answer:

x=9

Answer 2

Answer:

9

Step-by-step explanation:

3x-2=2x+7

3x-2x-2+2=2x-2x+7+2

x=9

3(9)-2=2(9)+7

27-2=18+7

25=25

(sin^2x+tan^2x+cos^2x)/(sec^2x) What trig identities are used in solving this as well.

Answers

The main one is the Pythagorean identity,

sin²(x) + cos²(x) = 1

By dividing both sides by cos²(x), you get the tan-sec variant:

sin²(x)/cos²(x) + cos²(x)/cos²(x) = 1/cos²(x)

tan²(x) + 1 = sec²(x)

since tan(x) = sin(x)/cos(x) and sec(x) = 1/cos(x).

So the given expression reduces to

(sin²(x) + tan²(x) + cos²(x)) / sec²(x)

= (1 + tan²(x)) / sec²(x)

= sec²(x) / sec²(x)

= 1

4. Triangle PSV is shown on the coordinate grid. The coordinates of each vertex of the triangle are integers. What is the slope of PV?​

Answers

Answer:

-4,1

Step-by-step explanation:

The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.

If the coordinates of each of the vertex on the coordinate grid:

P = (2, 4)

S = (3, 4)

V = (3, 0)

The slope of PV is -4.

What are coordinates in a graph?

The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.

The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.

We have,

Triangle PSV:

The coordinates of each of the vertex on the coordinate grid:

P = (2, 4)

S = (3, 4)

V = (3, 0)

The slope of PV:

Choose any two coordinates from the line PV.

V = (3, 0) = (A, B)
P = (2, 4) = (C, D)

The slope of PV:

= (D - B) / (C - A)

= (4 - 0) / (2 - 3)

= 4 / -1

= -4

Thus,

If the coordinates of each of the vertex on the coordinate grid:

P = (2, 4)

S = (3, 4)

V = (3, 0)

The slope of PV is -4.

Step-by-step explanation:

To isolate the variable, you need to divide both sides of the equation by three, using the division property of equality. 126/3=42 , and 3x/3=x , this gives you 42=x, or x=42, meaning the answer is D.

Two forces of 90 newtons and 58 newtons act simultaneously on an object. The angle between the two forces is 57°. Find the magnitude of the resultant, to the nearest 10th of a newton.

Answers

Answer:

131.0 N

Step-by-step explanation:

Let the 90 N force is acting a horizontal force on the object

Horizontal force = 90 + 58sin33

Vertical force = 58cos33

∴The resultant force = √(90 + 58sin33)² + (58cos33)²

The probability that a student has both box and a console is 1/6 and the P(B/A) = 0.378

What is probability?

Probability is a measure of the likelihood of an event occurring. The probability formula is defined as the possibility of an event happening being equal to the ratio of the number of favorable outcomes and the total number of outcomes. Probability of event to happen P(E) = Number of favorable outcomes/Total Number of outcomes.

Given here, the number of students with both video games is 30 thus

The probability that a student has both box and a console is 30/180=1/6

And the conditional probability P(B/A) is = 1/6/0.44

                                                                    = 0.378

Hence, The probability that a student has both box and a console is 1/6, and the P(B/A) = 0.378
