x = 25

Hi there !

4x - 25 = 25 + 2x

4x - 2x = 25 + 25

2x = 50

x  = 50 : 2

x = 25

Answer:

The number that both a rational number and a whole number is 22

Step-by-step explanation:

The whole numbers are the non-negative integers

The integers are rational numbers with denominators 1

The rational numbers are the numbers that can be written in the form of [tex]\frac{a}{b}[/tex] ,

b ≠ 0

Let us study the numbers in the figure:

The set of whole numbers ⊂ the set of integers ⊂ the set of rational numbers

∵ 22 ∈ the set of whole numbers

∴ 22 is a whole number

∴ 22 is a whole number and an integer

∴ 22 is a whole number, an integer, and a rational number

The set of integers ⊂ the set of rational

∵ -88 and -191 ∈ the set of integers

∴ -88 and -191 are integers

∴ -88 and -191 are integers and rational numbers

∵ -10.1 ∈ The set of rational numbers

∴ -10.1 is a rational number

Let us answer the question

→ We need to find a number that is a rational number and a whole number,

   which means it must ∈ to the set of the whole numbers

∵ We only have one number ∈ the set of whole numbers, it is 22

∴ The number that both a rational number and a whole number is 22

Answer:

x² + 8x + 16

Step-by-step explanation:

(x + 4)²

= (x + 4)(x + 4)

Each term in the second factor is multiplied by each term in the first factor, that is

x(x + 4) + 4(x + 4) ← distribute parenthesis

= x² + 4x + 4x + 16 ← collect like terms

= x² + 8x + 16

The radioactive isotopes of an element are known as radioisotopes.  The radioisotope sample that is given is Barium-139.

The radioactive isotopes of an element are known as radioisotopes. Atoms with an unstable mix of neutrons and protons, or excess energy in their nucleus, are also known as neutron-proton atoms.

As it is given that the initial mass of the sample at 12:02:00 PM is,

[tex]m_1=104.8\ kg[/tex]

The Mass of the sample at 4:11:00 PM is given as

[tex]m_2 = 13.1 kg[/tex]

So here since it is a sample of radioactive isotope so here we will say

[tex]m_2=m_1e^{-\lambda t}[/tex]

Now from the above data, we know that the time taken to reduce the mass is

[tex]\rm t = 4\ hours\ 9\ minutes = 4.15\ hours[/tex]

Further, from the above equation, we will have

[tex]13.1 =104.8 e^{-\lambda(4.15)}\\\\\lambda(4.15)=2.08\\\\\lambda = 0.50/ hour[/tex]

So here half-life is given as

[tex]\rm T_{\frac12}=\dfrac{ln2}{\lambda}\\\\ T_{\frac12} = 1.4\ hours[/tex]

Thus, here this isotope must be the one that will have a half-life of 1.4 hours

Therefore, it is nearly Barium-139.

Hence, the radioisotope sample that is given is Barium-139.

Answer:

Triangle =  1 1/2

Square = 10

Step-by-step explanation:

Given:

Triangle + Triangle + Square + Square = 23

Square - Triangle = 4 1/2

10 + 10 + 1 1/2 + 1 1/2 = 23

Hence, Square = 10 and Triangle = 1 1/2

Answer:

its a

Step-by-step explanation:

got it right on edge

Step-by-step explanation:

First we solve it.

I'll use substitution.

In the first equation y equals -2x+2 so we can apply that to the second equation

2y + 4x = 4

2(-2x+2) + 4x = 4

distribute

-4x+4+4x=4

simplify

4=4

To figure out how many solutions it has:

•If both side of the equal sign are exactly the same: Infinitely many

ex: 6x=6x

•If both sides of the equal sign do not match when completely simplified: No solutions

ex: 3x=-5x

•If it creates an equation: 1 solution

ex: x=3+2y

Since both sides of the equal sign are 4, we have infinitely many solutions.

5m-2m=3m 3n+n=4n so 3m+4n

Step-by-step explanation:

Train 1 speed be 'u'

Train 2 speed be 'v'

And v=2u

Speed=distance/time

Trains going in opposite directions

Relative speed= v-u (as train 1 I slower than train 2)

v-u=600/4

2u-u=150

u=150miles/hour

v=300miles/hour

Answer:

x = 25

Step-by-step explanation:

The sum of the three interior angles of a triangle is always 180°.

4x + 2x + 30 = 180

6x + 30 = 180

6x = 150

x = 25

Answer:

sum of the interior angles of a triangle =180

2× + 4× + 30=180

6× + 30= 180

6× + 30 = 180

6× = 180-30

6× =150

6×/6=150/6

×= 25

Step-by-step explanation:

Ok, so first...

a) if x is positive, it will remain x, so *x<7*

b) if x+3 is positive, it will be x+3<9 but you have to simplify it so you subtract 3 on both sides and get *x<6*

c) if y-8 is positive, it will stay like that, and you then add 8 on both sides to get *y>19*

g) if 3x-1 is positive, it will be 3x-1 greater than or equal to 18. add 1 on both sides and *3x > or = to 18*

4y+3 < or = 13. subtract 3 on both sides and you get *4y < or = 13*
