Answer:
x = 24
Step-by-step explanation:
3x-2(x-5)=14
remove the parentheses using distributive property
3x-2x-10=14
collect like terms
x-10=14
move constant to the right side and change the sign
x=14+10
calculate ( add the numbers together)
x = 24

What’s the surface area of 200 square inches ?
Answer:
5.77in
Step-by-step explanation:
A cube has 6 square faces, so each face would have area 200 sq in/6=33.33 sq in
Since the area of each face equals the square of the sides, the edge of the cube would be sqrt%2833.33sq+in%29= approx. 5.77 in

find the circumference of each circle round to the nearest tenth
Answer:
7) 75.4 yd
8) 34.56 mi
6) 81.68 cm
Step-by-step explanation:
The formula of circumference is: circumference (C) = 2 * π * r
7) The radius = 12 yd
π = 3.14
We can solve for C:
C = 2πr
C = 2(3.14)(12 yd)
C = 75.4 yd
8) The radius = 5.5 mi
π = 3.14
Solve for C:
C = 2πr
C = 2(3.14)(5.5 mi)
C = 34.56 mi
6) The diameter is 26. The radius is one half of the diameter; so the radius is 13.
We can solve for C:
C = 2πr
C = 2(3.14)(13 cm)
C = 81.68 cm
Hope this helpsss <3
Answer:
7) 75.36 8)34.54 9)81.64
Step-by-step explanation:
you can find this by using the formula diameter times pi (for pi use 3.14) or the formula 2times pi times radius. and for the diameter just multiply the radius by 2.

Ordena de forma creciente los siguientes números enteros, colocando el signo de desigualdad mayor (>) o menor (<) correspondiente entre ellos a) 32 ; −2 ; −11 ; 6 ; −7 ; 20 ; −21 ; −32 ; 30 ; −16
Answer:
El orden de forma creciente de los números enteros es:
-32< -21< -16< -11< -7< -2< < 6< 20< 30< 32
Step-by-step explanation:
Ordenar de forma creciente números enteros implica ordenarlos de menor a mayor. Esto es, debes considerar primero el número que posea el menor valor y luego ir ordenándolos a medida que su valor vaya aumentando, para dejar en último lugar al que posea el mayor valor.
Para ordenarlos debes tener en cuenta que:
todo número negativo es menor que cero, mientras que todo número positivo es mayor que cero. de dos enteros negativos es mayor el que tiene menor valor absoluto. de los enteros positivos, es mayor el que tiene mayor valor absoluto.Entonces, en este caso el orden de forma creciente de los números enteros es:
-32< -21< -16< -11< -7< -2< < 6< 20< 30< 32
You use the utility company’s budget plan for paying your home heating bills. You pay $75 a month for 9 months. Your actual bills are: September, $28.95; October, $46.15; November, $68.46; December, $109.34; January, $115.26; February, $94.19; March $75.66; April, $51.97; and May, $49.16. Compute the average for the 9 months
Answer:
$71.01Step-by-step explanation:
What is the average of a set of numbers?
An average is a number expressing the central or typical value in a set of data, in particular the mode, median, or (most commonly) the mean, which is calculated by dividing the sum of the values in the set by their number.
Given
September, $28.95;
October, $46.15;
November, $68.46;
December, $109.34;
January, $115.26;
February, $94.19;
March $75.66;
April, $51.97; and
May, $49.16.
Step two:
Total amount= 28.95+46.15+68.46+109.34+115.26+94.19+75.66+51.97+49.16= 639.14
Total number of monts= 9
Average= 639.14/9
Average= $71.01
Segment AB is the diameter of circle M. The coordinates of A are (1,6). The coordinates of M are (-3, 8). What are the coordinates of B
1) (-7,10)
2) (5,4)
3) (-1,7)
4) (-2,1)
Step-by-step explanation:
Let the midpoint formula be expressed as;
M(X,Y) = {x2+x1/2, y2+y1/2}
X = x2+x1/2
Y = y2+y1/2
Get x2
-3 = x2 + 1/2
-6 = x2 + 1
x2 = -6-1
x2 = -7
Get y2;
Y = y2+y1/2
8 = y2+6/2
16 = y2+6
Y2 = 16-6
y2 = 10
hence the coordinate of B is (-7, 10). Option A is correct

-x + 5 + 6x = 1 + 5x + 3
Answer:
There are no values of
x
that make the equation true.
No solution
Step-by-step explanation:
-x + 5 + 6x = 1 + 5x + 3
Group like terms
-x+6x+5=1+5x+3
Add similar elements:-x+6x=5x
5x+5=1+5x+3
Group like terms
5x+5=5x+1+3
Add the numbers 1+3=4
5x+5=5x+4
Subtract 5 from both sides
5x+5-5=5x+4-5
Simplify
5x=5x-1
Subtract 5x from both sides
5x-5x=5x-1-5x
Simplify
0=-1
The sides are not equal
No Solution

(U also have to explain the reasoning you used to find the value of P)
9514 1404 393
Answer:
P = 70 +4x
Step-by-step explanation:
From your previous work with the parking lot, you know its area is ...
A = 560 +32x
The width of the parking lot extension is (52 -20 -24) = 8 yards, so its area is ...
extension area = 8P
We want the extension area to be equal to the original area so that adding the extension will double the area:
extension area = A
8P = 560 +32x
P = 70 +4x . . . . . . divide by 8
When a number n is divided by 10000, the quotient is 1 and the remainder is 2011. The quotient and the remainder when n is divided by 2011 are respectively.
Answer:
[tex]Remainder = 1956[/tex]
[tex]Quotient = 5[/tex]
Step-by-step explanation:
Given
[tex]Dividend = n[/tex]
[tex]Divisor = 10000[/tex]
[tex]Quotient = 1[/tex]
[tex]Remainder = 2011[/tex]
Required
Determine the quotient and remainder when the divisor is 2011
First, we need to determine the value of n.
The relationship between the given parameters is:
[tex]Dividend = Quotient * Divisor + Remainder[/tex]
Substitute values in the above:
[tex]n = 1 * 10000 + 2011[/tex]
[tex]n = 10000 + 2011[/tex]
[tex]n =12011[/tex]
So, we divide 12011 by 2011 and record the quotient and divisor:
[tex]\frac{12011}{2011} =[/tex]
The integer division of 12011 and 2011 is 5.
The remainder is calculated using:
[tex]Dividend = Quotient * Divisor + Remainder[/tex]
Where
[tex]Dividend = 12011[/tex]
[tex]Quotient = 5[/tex]
[tex]Divisor = 2011[/tex]
So, Remainder =:
[tex]Remainder = 12011 - 2011* 5[/tex]
[tex]Remainder = 12011 - 10055[/tex]
[tex]Remainder = 1956[/tex]
Hence:
[tex]\frac{12011}{2011} = 5\ Remainder\ 1956[/tex]

Does the table show a proportional relationship, if so , what is the value of y when x is 10
Yes, the given table shows a proportional relation with constant of proportionality 1/3.
What are proportional relation?Two variables x and y are in proportional relation if the relation between then is in the form y = k x, where k is the constant of proportionality.
Or we can say for all pairs ( x, y ) , y/x = k , k is constant then the table containing (x, y) values shows a proportional relationship.
From given table
When x= 5 , y =[tex]1\frac{2}{3}[/tex] =5/3
Then, y/x = (5/3)/5 = 1/3 =k
When x =6 , y =2
Then, y/x = 2/6 = 1/3 =k
When x = 7 , y = [tex]2\frac{1}{3}[/tex] = 7/3
Then, y/x = (7/3) /7 = 1/3 =k
When x=8 , y =[tex]2\frac{2}{3}[/tex] = 8/3
Then , y/x = (8/3) / 8 = 1/3 =k
Thus for each pair (x, y) given in the table the ratio y/x is same , this ratio is say k = 1/3
Therefore, for the given table y/ x = k or y =k x with k = 1/3 , and the table shows a proportional relation with constant of proportionality 1/3.
