c + d, for c= (-6) and d = (- 12)
Answer:
-18
Step-by-step explanation:
1st- Subsitute the numbers
c + d c=-6 d=-12 (-6) + (-12)
Remember ( +, +) signs add ( +, - ) signs subtract
2nd- Add the two numbers (-6) + (-12) = -18
A student solved the given equation and justified every step except one. What is the missing reason? A) Associative property of addition B) Commutative property of addition C) Multiplicative property of equality D) Distributive property of multiplication over addition
Given:
The statements and reasons to solve an equation.
To find:
The missing reason.
Solution:
If a, b and c are three real number, then
Associative property of addition : [tex](a+b)+c=a+(b+c)[/tex]
Commutative property of addition : [tex]a+b=b+a[/tex]
Multiplicative property of equality : [tex]a=b\Leftrightarrow ca=cb[/tex]
Distributive property of multiplication over addition : [tex]a(b+c)=ab+ac[/tex]
In the given step, [tex](x+-3)+3[/tex] is written as [tex]x+(-3+3)[/tex].
It means, only parenthesis are changed, which is possible by Associative property of addition.
So, the missing reason is Associative property of addition.
Therefore, the correct option is A.

The following are rules for repeating patterns. For which rule will the 12th shape be a circle?
A. Triangle, Circle,Square
B. Circle, Square
C. Rectangle,Circle
Circle, Circle, Triangle
The third pattern because you can divide 12 by the number of shapes in the sequence and start counting from the remainder.
In this case choice C has 5 shapes. 12/5 is 2, with a remainder of 2.
The second term in choice C is Circle, so choice C is the answer.
Of course, you can also list them all out.
If there is no remainder when you divide then the 12th term is the last term in the sequence.

yes

A new concert venue just opened in downtown Augusta and they are in the process of deciding how many tickets they can sell for each show. The venue has three levels, two general admission that only have standing room, and one level with 240 seats. The first level of standing room is a square with one side measuring 80'. The second level, also standing room, is a rectangle measuring 120' by 30' ft. The third level has 240 seats. The venue thinks each person will occupy 2.5 square feet. How many tickets should they sell?
Answer:
4,240 tickets
Step-by-step explanation:
The first level of standing room is a square with one side measuring 80'.
Area of the first level = length^2
= 80^2
= 6,400 square ft
The second level, also standing room, is a rectangle measuring 120' by 30' ft.
Area of the second level = length × width
= 120 × 30
= 3,600 square ft
Total area of the standing rooms = (6,400 + 3,600) square ft
= 10,000 square ft
Each person in the standing room will occupy 2.5 square ft
Number of Persons that will occupy the standing room = Total area of the standing rooms / 2.5 square ft
= 10,000 square ft / 2.5 square ft
= 4,000
Therefore the number of Tickets that should be sold
= Number of seats + Number for standing Room
= 240 + 4000
= 4,240 tickets

Does anybody know the the endpoints of these segments
Answer:
D, (13, 4.5)
Step-by-step explanation:
(question asked for midpoint so my bad if this isnt what you wanted)
to calculate the median of a vector, you would have to do a simple calculation to get the answer
for the x coordinate, (9 + 17) / 2 would be 13
for the y coordinate, 5 + 4 / 2 would be 4.5
combining those would give you the answer (13, 4.5)

Find the value of x.
x=
Answer:
x = 14
Step-by-step explanation:
These angles are complementary angles, meaning they have a sum of 90°.
4x + 1 + 2x + 5 = 90
6x + 6 = 90 (Added like terms.)
6x = 84 (Subtracted 6 on both sides.)
x = 14 (Divided 6 on both sides.)
[tex]\sf \longmapsto \: (4x + 1) + (2x + 5)[/tex]
It has a sum of 90 as the given angles are complementary angles.[tex]\sf \longmapsto \: 4x + 1 + 2x + 5 = 90[/tex]
[tex]\sf \longmapsto4x + 2x + 1 + 5 = 90[/tex]
[tex]\sf \longmapsto6x + 6 = 90[/tex]
[tex]\sf \longmapsto6x = 90 - 6[/tex]
[tex]\sf \longmapsto \: 6x = 84[/tex]
[tex]\sf \longmapsto \: x = \cancel\dfrac{84}{6} [/tex]
[tex]\sf \longmapsto \: x = 14[/tex]
[tex] \boxed{\sf \boxed {{ \sf \red{\: x = 14 }}}}[/tex]
slope of 1/2 that passes through the point (6,-4) in slope-intercept form
Answer:
y=1/2x-7
Step-by-step explanation:
slope intercept form: y=mx+b
mx= slope
b= y-intercept
y=1/2x+b
Now plug in 6 for x and -4 for y bc 6 is in the x-value and -4 is in the y-value.
-4=1/2(6)+b
-4=3+b
Subtract 3 from both sides
b=-7
y=1/2x-7
The equation of the line with a slope of 1/2 that passes through the point (6, -4) in slope-intercept form is y = 1/2x - 7.
To find the equation of a line with a slope of 1/2 that passes through the point (6, -4), we can use the point-slope form of a linear equation, which is:
y - y₁ = m(x - x₁)
Plugging in the values, we have:
y - (-4) = 1/2(x - 6)
y + 4 = 1/2(x - 6)
Now, let's convert the equation to slope-intercept form, which is in the form of y = mx + b, where m represents the slope and b represents the y-intercept.
Expanding and rearranging the equation:
y + 4 = 1/2x - 3
y = 1/2x - 7
Therefore, the equation of the line with a slope of 1/2 that passes through the point (6, -4) in slope-intercept form is y = 1/2x - 7.

Find three consecutive even integers such that the sum of the first and third increased by 18 is equal to three times the second.
Answer:
16, 18 and 20Step-by-step explanation:
x - an integer
2x - an even integer (the first)
Even integers increase by 1 so:
2x+2 - next consecutive integer (the second)
3(2x+2) - three times the second
2x+4 - the third consecutive integer
2x+2x+4 - the sum of the first and third
2x+2x+4+18 - the sum of the first and third increased by 18
2x+2x+4+18 = 3(2x+2)
4x + 22 = 6x + 6
-6 -6
4x + 16 = 6x
-4x -4x
16 = 2x
2x = 16
2x+2 = 18
2x+4 = 20
Check: 16+20+18=54; 3×18=54

3.[]x+y greater than 500
5.[]x+y greater than or equal to 500
Answer:
The answer should be x+y greater than or equal to 500
Step-by-step explanation:
hope this helps. :)
The inequalities best represents the situation for savings account is; option 3: x+y greater than or equal to 500.
What is the meaning of the term inequalities?In mathematics, an inequality is a connection between two representations or values which are not equal to each other.Once inequalities are linked, they can be crossed. As a result, if an is greater than b and b is greater than c, a will be greater than c as well.By multiplying all sides of a inequality by such a negative sign, the sign is reversed.For the given question,
