The value of x in the equation 5x+9=5+3x is 2.

When we have an equation, we can divide it into two parts, the left and right sides. In short, we call the equation LHS and RHS.

If we get both LHS and RHS as equal values, we can say that the equation is true; otherwise, the equation does not hold for at least some real-number values.

Given that,

5x+9=5+3x

Bring x terms to LHS and constants to RHS

5x-3x=5-9

we get,

2x=-4

taking 2 to RHS

in LHS we multiply with two so it becomes divided on RHS

so

x=4/-2

x=-2

Thus, the value of x in the equation 5x+9=5+3x is 2.

The angle that is equal to 90° is ∠ABC.

What is an angle?

An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are in the plane where the rays are located. The meeting of two planes also creates angles. Dihedral angles are these.

Here, we have

Given the following diagram and we have to determine that in circle O, which angle is equal to 90°.

We concluded that

If one side of a triangle inscribed in a circle is the diameter of the circle, then the triangle is a right triangle and the angle opposite the diameter is the right angle.

Equations may be solved and x-intercepts can be found very quickly when a quadratic expression is in factored form and equal to 0. Vertices, as well as the expression's maximum and minimum values, can also be identified.

A polynomial equation of degree 2 is a quadratic equation. A quadratic equation has the conventional form a[tex]x^2[/tex] + bx + c=0, where a, b, and c are all real values and a[tex]\neq[/tex]0.

The quadratic function y=a[tex]x^2[/tex] + bx + c, whose graph will be a parabola, is obtained if we substitute 0 with y.

The solutions to the equation a[tex]x^2[/tex]+bx+c=0 will be at the spots where the graph intersects the x-axis. In other words, if the polynomial a[tex]x^2[/tex]+bx+c can be factored to (x-p)(x-q), then (x-p)(x-q)=0 or (x-p)(x-q)=0 according to the zero product property. As a result, p and q are the x-intercepts of the quadratic equation and the solutions to the equation a[tex]x^2[/tex] + bx + c=0.

The value of b is equal to seven

if the tangent of x degrees is equal to four-thirds, the triangle's area is 10.5 units, and the length of the NM is 2b units. In this case, b = 7, hence the last choice is right.

Triangles are described as having right angles.Has three sides in the normal sense, where the total of any two sides is always greater than the third side. One kind of triangle is the right angled triangle.

A right angle triangle is one that has angle

between its two sides .

We also have a number of sides.

NM = 2b, LM = 10.5 length of side

x's tangent, tan x = 4/3

We must figure out what b is worth.

triangular base = LM = 10.5

As is common knowledge, the tangent of any angle equals the perpendicular to base ratio.

=>4/3 = 2b / 10.5

Tan x = 4/3 = LM/NM, thus.

=>4x 10.5 = 2b x 3

1. 60 ft = 7.3 yd (60 ft * 0.3333 = 19.98 ft)

2. 100 meters = 10,000 cm (100 m * 100 = 10,000 cm)

3. 5 hr = 300 min (5 hr * 60 = 300 min)

4. 12 meters = 39.37 ft (12 m * 3.281 = 39.37 ft)

5. 16 in = 40.64 cm (16 in * 2.54 = 40.64 cm)

6. 5 liters = 1.32 qt (5 L * 0.2642 = 1.321 qt)

7. 2076 cm = 2.29 yd (2076 cm * 0.0109 = 22.7 yd)

8. 15 pounds = 6,803.86 grams (15 lb * 453.59 = 6,803.86 g)

The two consecutive natural numbers are 2 and 3.

Let x be the smaller number. Hence, the larger number will be x + 1.

The product of these two consecutive natural numbers is x(x + 1). It is stated in the problem that this product is 1.5 times as big as the square of the smaller number, x². So we can set up the equation:

x(x + 1) = 1.5x²

Expanding and simplifying the equation:

x² + x = 1.5x²

0.5x² - x = 0

x(0.5x - 1) = 0

x = 0 or 0.5x - 1 = 0

x = 0 or 0.5x = 1

x = 0 or x = 2

The smaller number cannot be 0, so the solution for the smaller number is x = 2 and the larger number is x + 1 = 2 + 1 = 3.

Therefore, the two consecutive natural numbers are 2 and 3.

What is a rectangle?

A Rectangle is a four sided-polygon, having all the internal angles equal to 90 degrees. The two sides at each corner or vertex, meet at right angles. The opposite sides of the rectangle are equal in length which makes it different from a square.

For example, if one side of a rectangle is 20 cm, then the side opposite to it is also 20 cm.

Perimeter of a Rectangle:-

The perimeter of a rectangle is defined as the total distance covered by the outer boundary of the rectangle. It is measured in unit length. The formula of perimeter is given by:

Perimeter, P = 2 (Length + Width)

Now,

The equation of line that passes through the point (-3, 8) and has a slope of 4 is y = 4x + 20.

In the given question, we have to find the equation of the line that passes through the point (-3, 8) and has a slope of 4.

From the given question, m = 4 and point (x(1), y(1)) = (-3, 8).

To find the equation of line we put the values in the equation:

y - y(1) = m(x - x(1))

Now putting the value

y - 8 = 4(x - (-3))

Now simplifying the bracket first

y - 8 = 4(x + 3)

Now solving the expression using the distributive property

y - 8 = 4x + 12

Add 8 on both side, we get

y = 4x + 20

Hence, the equation of the line that passes through the point (-3, 8) and has a slope of 4 is y = 4x + 20.

Total cost in single service crew is greater than double service crew. So, double service crew is cheaper.

We have, a crew of mechanics at the highway department garage repair vehicles. In case of poisson distribution,

λ = 3 vehicles every 12 minutes

= 3×60/12 = 3× 5

λ = 15 vehicles per hour

When time distribution is approximates an exponential distribution,

The mechanic crew can service an average, μ = 3 vehicles every 10 minutes

μ = 3×60/10 = 18 vehicles per hour

Cost for one service crew =$150 per hour

Cost associated with lost productivity from the breakdown or wait cost

=$50 per hour

For single crew, number of vehicles out of cost, Lₛ = 15/(18 - 15) = 15/3 = 5

Single service crew cost = $150 per hour

wait cost = $5×50 = $250 per hour

Total cost = $400 per hour

For double service crew, Number of vehicles out of service cost = 15/(36 - 15)

= 15/21 = 0.7143

Double service crew cost = 2× $150

= $300

Wait cost = $0.7143×50 = $35.715

Total cost = $335.715 per hour

As we see, the double service crew is cheaper.

There are 5040 possible combination of 7 letter words using 3 vowels and 4 consonants.

We know that the word must have 4 consonants and 3 vowels. We have the following vowels in "mathisfun" : i, a, and u.

We have 7 letters that can be used as consonants: m,t,h,s,f,n.

First we need to find the number of ways to choose the 4 consonants out of 7 possible letters, which is 7C4 = 35.

Then we need to find the number of ways to arrange the 4 consonants and 3 vowels, which is 4!*3! = 144

Finally, we multiply those two values together: 35 * 144 = 5040.
