Is ......... a rational number ?

Answer:

d 80

Step-by-step explanation:

Answer:

D

Step-by-step explanation:

The difference between 63y and 35y is 28y. 28/2=14, 28/4=7, 28/7=4, 28/9=not whole number so I'm not doing the math, and to make sure we are right, 28/14=2

Answer:

Step-by-step explanation:

[tex]63y-35y\\=28y[/tex]

[tex]\frac{28y}{2} = 14y\\\\\frac{28y}{4} = 7y\\\\\frac{28y}{7} =4y\\\\\frac{28y}{14} = 2y\\\\\frac{28y}{9} =3.1111y[/tex]

Answer:

Step-by-step explanation:

-5y +15 = 3x

divide both sides by 3 to find x

-5y/3 + 5 = x

to find Y you have to isolate it so you add 5y to both sides and subtract 3x from both sides to get

-3x + 15 = 5y

then to find y divide both sides by 5

-3x/5 + 5 = y

Answer: Answer is in the steps

Step-by-step explanation:

A)  First convert 65 miles to kilometers  

65 miles to kilometers  is 104.607  

Convert 1 hour to minute and that will be 60 minutes because 60 minutes makes and hour.

Now divide the kilometers by the number of minutes

104.607 / 60 = 1.74345  

The speed will be 1.74345 kilometers per minute.

B) Convert 3.5 hours to minutes.

3.5 hours is the same as 210 minutes    

Now multiply it by 1.74345 to determine how many kilometers you have traveled.

1.74345 * 210 = 366.1245

You will travel 366.1245 kilometers in 3.5 hours.

Answer:  3. Distributive

Step-by-step explanation:

Distributive property of multiplication over addition is the only property that is require to multiply an expression to the other expression with two or more than two terms.

For example: a (b+c)= a b+ac  , where a,b,c can be any expression.

Given expression:  -5(x-3) = -5x +15 , which illustrates the distributive property of multiplication over addition.

Hence, the correct option is 3. Distributive.

The rest of properties cannot work for multiplication over addition as they are used for one operation.

The value of [tex]x[/tex] is 7.

Important information:

The given equation can be written as:

[tex]\dfrac{2}{3}(9x)-\dfrac{2}{3}(6)=4x+10[/tex]

[tex]6x-4=4x+10[/tex]

[tex]6x-4x=4+10[/tex]

[tex]2x=14[/tex]

Divide both sides by 2.

Answer:

[tex]\bold{\angle NLM = 10^\circ}[/tex]

Step-by-step explanation:

Given a ΔLMN.

Line LN is extended to point O.

such that:

[tex]\text{m}\angle MNO = (5x-13)^{\circ}[/tex]

[tex]\text{m}\angle NLM = (x-4)^{\circ}[/tex] and

[tex]\text{m}\angle LMN = (2x+19)^{\circ}[/tex]

To find:

[tex]\text{m}\angle NLM=?[/tex]

Solution:

Kindly refer to the attached image for the given triangle and dimensions of angles.

Let us recall the external angle property of a triangle:

The external angle of a triangle is equal to the sum of two opposite internal angles.

i.e.

[tex]\angle MNO = \angle NLM + \angle LMN\\\Rightarrow 5x-13 = x-4+2x+19\\\Rightarrow 5x-13 = 3x+15\\\Rightarrow 5x-3x = 13+15\\\Rightarrow 2x=28\\\Rightarrow x =14[/tex]

Putting the value of [tex]x[/tex] in [tex]\angle NLM[/tex].

[tex]\angle NLM=14-4 \\\Rightarrow \bold{\angle NLM = 10^\circ}[/tex]

Answer:

18

Step-by-step explanation:

The solution is Option B.

The value of the modulus function is A = 18

Regardless of the sign, a modulus function returns the magnitude of a number. The absolute value function is another name for it.

It always gives a non-negative value of any number or variable. Modulus function is denoted as y = |x| or f(x) = |x|, where f: R → (0,∞) and x ∈ R.

The value of the modulus function is always non-negative. If f(x) is a modulus function , then we have:

If x is positive, then f(x) = x

If x = 0, then f(x) = 0

If x < 0, then f(x) = -x

Given data ,

Let the modulus function be represented as A

Now , the value of A is

A = 6 | 5 - c | + 2c  be equation (1)

Now , when the value of c = 6

Substituting the value of c in the equation , we get

A = 6 | 5 - 6 | + 2 ( 6 )

A = 6 | -1 | + 2 ( 6 )

The value of the modulus function always returns a positive value ,

So , A = 6 ( 1 ) + 2 ( 6 )

A = 6 + 12

A = 18

Therefore , the value of A is 18

Hence , the modulus function is A = 18

Step-by-step explanation:

Hey, there!

Here,

Given that:

[tex] = 25 {x}^{2} - 4[/tex]

we need to find factor,

As it is in a^2-b^2 form as per its factor (a+b) (a-b), keeping same formula here,

25x^2 means (5x)^2

and 4 means 2^2

Now, it would be,

[tex] = ( {5x)}^{2} - {2}^{2} [/tex]

[tex] = (5x + 2)(5x - 2)[/tex]

Therefore, it's factor would be (5x+2)(5x-2).

Answer:

4x + 16

Step-by-step explanation:

The area of the shaded region = area of the outer rectangle - area of the inner rectangle

Area of rectangle = l*w

Area of outer rectangle, where length (l) = (x + 5), and width (w) = (x + 4):

Area = (x + 5)(x + 4)

Expand

x(x + 4) +5(x + 4)

x² + 4x + 5x + 20

area of outer rectangle = x² + 9x + 20

Area of inner rectangle, where length (l) = (x + 4), and width (w) = (x + 1):

Area = (x + 4)(x + 1)

Expand

x(x + 1) +4(x + 1)

x² + x + 4x + 4

Area of inner rectangle = x² + 5x + 4

Area of shaded region = (x² + 9x + 20) - (x² + 5x + 4)

x² + 9x + 20 - x² - 5x - 4

Collect like terms together

x² - x² + 9x - 5x + 20 - 4

4x + 16

Area of the shaded region = 4x + 16
