10x-2y=68(x=6 4/5 or 6.8 and y=-34)

Answer:

Hope it will help you.

Step-by-step explanation:They are equal because the diagonals of a rectangle are equal.

The required value of the x is given as x = 12, and Option C is correct.

The rectangle is 4 sided geometric shape whose opposites sides are equal in length and all angles are equal to 90°.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

here,
For the rectangle figure,
The measure of the diagonal is always equal,
So,
10x + 8 = 9x + 20
10x - 9x = 20 - 8
x = 12

Thus, the required value of the x is given as x = 12, and Option C is correct.

Answer:

∠Q = ∠S = 101

Step-by-step explanation:

The above quadrilateral is called a kite

so ∠Q = ∠S

Q + S + 110 + 48 = 360

Q + S = 202

Q = S = 202/2 = 101

Step-by-step explanation:

1. The sum of all angles in a triangle is 180°

75° + 60° + x° = 180°

135° + x° = 180°

x° = 55°

2. The sum of all angles in a triangle is 180°

70° + 70° + x° = 180°

140° + x° = 180°

x = 40°

3. The sum of all angles in a triangle is 180°

1 : 2: 5 = 1x:2x:5x

1x + 2x + 5x = 180°

8x = 180°

x = 22.5°

2x = 45°

5x = 112.5°

4. The sum of all angles in a triangle is 180°. The angle in a line is 180°

Missing angle is 180° - 123° = 57°

The sum of angles in a triangle is 180°

57* + x° + 90* = 180°

57° + x° = 90°

x = 33°

5. We know that the sum of angles in a triangle is 180°. We can subtract the values of the two other angles from 180* to find the missing angle.

Aisha is 8 years old and her sister is 12 years old.

From the information given;

If Asher’s sister is eight years older than Asher, then;

y = x + 8

If their combined agee is 20, then;

x + y = 20

Substitute equation 1 into 2 to have:

x + 8 + x = 20

2x + 8 = 20

2x = 20 - 8

2x = 18

x = 8

Since x + y = 20

y = 20 - 8

y = 12

Hence Aisha is 8 years old and her sister is 12 years old.

Answer:

Numerical expressions contain numbers, while algebraic expressions contain variables and numbers.

Answer:

The expression cos^-1 (3/5) has an infinite number of values is a true

Step-by-step explanation:

We are given a expression as:

Let us equate this expression to be equal to some angle theta(θ)

i.e.

Let

As we know that the limit point of the cosine  function is [-1,1]

i.e. it takes the value between -1 to 1 and including them infinite number of times.

Also,

-1< 3/5 <1

This means that the cosine function takes this value infinite number of times.

That is there exist a infinite number of theta(θ) for which:

i.e. the expression:

has infinite number of values.

The expression is equivalent to [tex]\rm2( \dfrac{3}{4}x) + 2(7) -3(\dfrac{1}{2}x) + (-3) (-5)\\[/tex].

Expression; [tex]\rm 2(\dfrac{3}{4}x+7) -3(\dfrac{1}{2}x-5)[/tex]

Which expressions are equivalent to the given expression.

Expression; [tex]\rm 2(\dfrac{3}{4}x+7) -3(\dfrac{1}{2}x-5)[/tex]

To solve the given expression follow all the steps given below.

By applying the distributive property of multiplication;

[tex]\rm a(b+c) = ab+ac[/tex]

Then,

The equivalent expression is,

[tex]\rm 2(\dfrac{3}{4}x+7) -3(\dfrac{1}{2}x-5)\\ \\ \rm (2 \times \dfrac{3}{4}x) + 2(7) -3(\dfrac{1}{2}x) + (-3) (-5)\\ \\ 2( \dfrac{3}{4}x) + 2(7) -3(\dfrac{1}{2}x) + (-3) (-5)\\[/tex]

Hence, the expression is equivalent to [tex]\rm2( \dfrac{3}{4}x) + 2(7) -3(\dfrac{1}{2}x) + (-3) (-5)\\[/tex].

She spoke for 2 minutes in Hungarian and 3 minutes in Polish.

Step-by-step explanation:

Set up a system of equations to solve this.

h = time in Hungarian

p =time in Polish

p + h = 5

190p - 150h = 270

Solve using substitution.

p = 5 - h

190(5 - h) - 150h = 270

Distribute/simply.

950 -340h = 270

[tex]\frac{-340h}{-340} =\frac{-680}{-340} [/tex]

h = 2

Answer:

720 degrees.

Step-by-step explanation:

The sum of the interior angles of a convex polygon with  n  sides is

180(n - 2)  degrees.

In this case,  n = 6 sides, so the angle sum is

180(6 - 2) = 180(4) = 720 degrees.

The reason this works is that if you draw a diagonal from one vertex to the others (see attached image), you get 2 fewer triangles than the number of sides.  Each triangle contains a total of 180 degrees, so the total of all the interior angles is 180(n - 2).

ABCD is a parallelogram ⇒ BE = DE

So: 7x - 12 = 3x + 4

⇔ 7x - 3x = 4 + 12

⇔ 4x = 16

⇔ x = 16/4 = 4

⇒ BE = 7(4) - 12 = 28 - 12 = 16

⇒ DE = 3(4) + 4 = 12 + 4 = 16

⇒ BD = BE + DE = 16 + 16 = 32

Answer: BD = 32

Answer:

X=4

Step-by-step explanation:

Answer:

x=4

Step-by-step explanation:

First, you need to add 5 to both sides to isolate 2x:

2x-5=3

2x-5+5=3+5

2x=8

Second, you need to divide both sides by 2 to isolate x:

2x=8

2x/2=8/2

x=4

Thus, our solution is x=4

The result of the limit is [tex]\infty[/tex].

The limit that we want to find is:

[tex]\lim_{t \rightarrow 0} \frac{1}{t\sqrt{1 + t}} - \frac{1}{t}[/tex]

Using the common factor, we have that:

[tex]\lim_{t \rightarrow 0} \frac{1}{t\sqrt{1 + t}} - \frac{1}{t} = \lim_{t \rightarrow 0} \frac{1}{t} \left(\frac{1}{\sqrt{1+t}} - 1\right)[/tex]

Rationalizing the expression inside the parenthesis:

[tex]\left(\frac{1}{\sqrt{1+t} - 1}\right) \times \frac{\sqrt{1+t} + 1}{\sqrt{1+t} + 1} = \frac{\sqrt{1+t} + 1}{t}[/tex]

Then, the limit is:

[tex]\lim_{t \rightarrow 0} \frac{1}{t} \left(\frac{1}{\sqrt{1+t} - 1}\right) = \lim_{t \rightarrow 0} \frac{1}{t^2} \sqrt{1+t} + 1[/tex]

Applying lateral limits:

[tex]\lim_{t \rightarrow 0^-} \frac{1}{t^2} \sqrt{1+t} + 1 = \infty[/tex]

[tex]\lim_{t \rightarrow 0^+} \frac{1}{t^2} \sqrt{1+t} + 1 = \infty[/tex]

Since the lateral limits are equal, the limit goes to infinity.
