First you have to know what a natural number is.
They are all the integers from 1 to infinity.
Naturally they are closed for addition. 3 + 9 = 12. You can make as many examples as you like. You will not get anything outside the natural numbers.
3934859433993393390 + 4 + 22 is still going to give you a natural number.
Subtraction is a different matter.
44 - 100 is not in the natural number system.
Multiplication is OK.
5555 * 44444 still is a member of the natural numbers.
What about division? Remember, all you need is one example that doesn't work to say that the natural numbers aren't closed. Ready. How about
33/83?
If the perimeter of a rectangle
is 124m & the width is 35m,
what is the length?
Let length be x
ATQ
[tex]\\ \sf\longmapsto 2(Length+Width)=124[/tex]
[tex]\\ \sf\longmapsto 2(x+35)=124[/tex]
[tex]\\ \sf\longmapsto 2x+70=124[/tex]
[tex]\\ \sf\longmapsto 2x=124-70[/tex]
[tex]\\ \sf\longmapsto 2x=54[/tex]
[tex]\\ \sf\longmapsto x=\dfrac{54}{2}[/tex]
[tex]\\ \sf\longmapsto x=27m[/tex]

Find the y-intercept of the line: 6x – 3y +6=0
Answer:
Step-by-step explanation:
The y-intercept exists where the x coordinate is 0. Therefore, we can find it by plugging in a 0 for x and solving for y:
6(0) - 3y + 6 = 0 and
-3y + 6 = 0 and
-3y = -6 so
y = 2

Solve 4(x + 1) = 4x + 4
Answer:
x is all real numbers
Step-by-step explanation:
4(x + 1) = 4x + 4
Distribute
4x+4 = 4x+4
Subtract 4x from each side
4x+4-4x = 4x+4-4x
4=4
This is always true so there are infinite solutions
x is all real numbers

[tex] \frac{4c}{h} - k[/tex]
Step-by-step explanation:
well that is the answer
Answer:
s = (4C/h) - k
Step-by-step explanation:
C = ((s + k)/4)h
multiply by 4/h
4C/h = s + k
subtract k
s = (4C/h) - k

You have $200 in a savings account and $100 in a checking
account. Each week, you add $50 to your savings account and $30 to your
checking account.
a. Write algebraic expressions that represent the amount of money in each
bank account after w weeks.
b. Write an expression in simplest form that represents the total amount of
money in both accounts after w weeks.
c. How much money do you have in both accounts after 5 weeks?
Answer:
a. Savings account: 200 + 50w Checking account: 100 + 30w
b. 300 + 80w
c. 700
Step-by-step explanation:
b. 200 + 50w + 30w + 100 Combine like terms. 300 + 80w
c. 300 + 80w. w=5. 300 + (80*5) = 300 + 400 = 700

Answer:
Ithink the answer is 6 hope it helps please mark as brainliest
Answer:
a^2+3a+2
Step-by-step explanation:
(a + 1) × (a + 2)
a x a = a^2
a x 2 = 2a
1 x a = 1a
1 x 2 = 2
a^2 +2a+1a+2
2a+1a =3a

Trapezoid p is the image of trapezoid P after a translation. Y 7+ . р на дъл от - 1 -7-6-5-4-3-2-1 -2+ 11 2 3 4 5 6 7 1 PY 1 - - -51 -67 Which statement correctly describes the translation of trapezoid P to create the image Pl? A. 3 units to the right and 5 units down B. 4 units to the right and 1 units down O C. 8 units to the right and 5 units down D. 9 units to the right and 6 units down
Answer:
C. 8 units right and 5 units down
Step-by-step explanation:
since it's only a translation, take one point as an example. lets say the bottom right point on trapezoid P is point A, and the translated point on P' is A'. the coordinates of A are (-3,2) while the coordinates of A' are (5,-3). (-3+x,2+y)=(5,-3). -3+x=5, x=8; 2+y=-3, y=-5
2. Find the domain of the function (f/g)(x) where f (x)= x^2 – 9 and g(x)= x^2 - 4x+3
A (-infinity, infinity)
B (-infinity, 1) (1, infinity)
C (infinity, 1) (1,3) (3, infinity)
D (-infinty, -3) (-3,-1)(-1, infinity)
Answer:
I think you mean C.
Step-by-step explanation:
f(x) / g(x) = (x + 3)(x - 3)
==========
(x - 3)(x - 1)
f(x)/g(x) = (x+3) / (x - 1)

(5m-4)/6 -1 = 4m - (3m+10)/2
pls answer fast
Answer:
m = 2Step-by-step explanation:
[tex] \frac{(5m - 4)}{6} - 1 = 4m - \frac{(3m + 10)}{2} [/tex]
[tex] = > \frac{5m - 4 - 6}{6} = \frac{8m - 3m - 10}{2} [/tex]
[tex] = > \frac{5m - 10}{6} = \frac{5m - 10}{2} [/tex]
[Cross Multiplication]
=> 2(5m - 10) = 6(5m - 10)
=> 10m - 20 = 30m - 60
=> 60 - 20 = 30m - 10m
=> 40 = 20m
[tex] = > m = \frac{40}{20} [/tex]
=> m = 2 (Ans)
