The value of x is -8 in the equation.
How to calculate the equation?It should be noted that the information is that the number 80 is the product of "-10" and x.
This will be represented as:
-10 × x = 80
-10x = 80
Divide both side by -10
-10x/-10 = 80/-10
x = -8
Therefore, the value of x is -8.

Answer: greatest is A.
Step-by-step explanation:
A student club started a fundraising effort to support animal rescue organizations. The club sent an information flyer home to the n students in the school. It says, "We welcome donations of any amount, including any change you could spare!" Their goal is to raise T dollars, and to donate to a cat shelter and a dog shelter.
Match each quantity to an expression, an equation, or an inequality that describes it.
The dollar amount the club would have if every student at the school donated a quarter to the cause.
The dollar amount the school will raise is given by the expression 0.25n, where n is the number of students.
A combination of terms through addition, subtraction, multiplication, division, and other operations is known as an algebraic expression (or variable expression).
A connection that compares two numbers or other mathematical expressions inequitably is known as an inequality in mathematics.
The dollar amount the club would have if they reached one-fourth of their goal= [tex]\frac{1}{4} T[/tex]The dollar amount the club would have if every student at the school donated a quarter to the cause =[tex]\frac{1}{4} n[/tex]The dollar amount the club could donate to the cat shelter if they reached their goal and gave a quarter of the total donation to a dog shelter= [tex]\frac{3}{4} T[/tex]Therefore the dollar amount the school will raise is given by the expression 0.25n or [tex]\frac{1}{4} n[/tex] , where n is the number of students.

The coordinates of the new triangle are P' = (5, 3), K' = (3, 1) and Y' = (1, 4)
How to determine the coordinates of the new triangle?The coordinates of the triangle in the figure are
P = (-5, -3)
K = (-3, -1)
Y = (-1, -4)
The transformation is given as 180 degrees rotation
The rule of this transformation is
(x, y) = (-x, -y)
When this is applied on the triangle, we have the coordinates of the new triangle to be
P' = (5, 3)
K' = (3, 1)
Y' = (1, 4)
Hence, the coordinates of the new triangle are P' = (5, 3), K' = (3, 1) and Y' = (1, 4)

What is the value of cosine (startfraction 4 pi over 3 endfraction)? negative startfraction startroot 3 endroot over 2 endfraction negative one-half one-half startfraction startroot 3 endroot over 2 endfraction
The value of Cos(4π/3) is (-1/2) i.e., negative one half.
The given function is Cosine (Start fraction 4 pi over 3 end fraction) and this can be written simply as,
Cos(4π/3)
On splitting 4π/3 in two parts, this can also be written as
= Cos(π + (π/3))
(π + (π/3)) lies in the third quadrant and in the third quadrant the value of cosine function is negative. So, using quadrant sign for cosine function, this can be written as
= -Cos(π/3)
Now, Substitute the value of Cos(π/3) = 1/2.
= (-1/2)
Cos(4π/3) = (-1/2)
The value of Cos(4π/3) is (-1/2) i.e., negative one half.

What is the equation of this
perpendicular line?
y = x + [?]
The equation of the perpendicular line is y = x + 15.
How to determine the equation of the perpendicular line
In this problem we need to determine the equation of the line perpendicular to another line, that intersects at the point (x, y) = (- 5, 10). The explicit form of the equation of the line is defined by the following first order polynomial:
y = m · x + b
Where:
m - Slopeb - y-Interceptx - Independent variabley - Dependent variableThe first line has a slope - 1 and the slope of the second line is:
m' = - 1 / m
m' = 1
Then, the intercept of the second line is:

Peyton needs to order some new supplies for the restaurant where she works. The restaurant needs at least 732 forks. There are currently 287 forks. If each sentence on sale contains 10 forks right and solve an inequality which can be used to determine X, The number of sets of forks Peyton could buy for the restaurant to have enough forks
Peyton needs to buy at least 45 sets for the restaurant to have enough forks.
Let the number of sets of forks be represented by 'x'. according to the question there are 10 forks in each set.
Since there are currently 287 forks available in the restaurant, and the restaurant needs at least 732 forks.
The inequality used to represent the given scenario is given by:
10x + 287 ≥ 732
10x ≥ 445
x ≥ 44.5
As Peyton cannot buy 44.5 sets of forks so we round it off to 45.
Therefore, he requires 45 sets in total.

The sum of three lengths of a fence ranges from 31 to 40 inches. two side lengths are 9 and 12 inches. if the length of the third side is x inches, write and solve a compound inequality to show the possible lengths of the third side. 31 ≤ x ≤ 40 22 ≤ x ≤ 28 10 ≤ x ≤ 19 9 ≤ x ≤ 12
If two side lengths of a fence are 9 and 12 inches and the sum of the three lengths ranges from 31 to 40 inches, then the length of the third side, x, can be presented by the compound inequality 10 < x < 19.
Inequality refers to the relationship between two non-equal expressions. It can be denoted by > for greater than, < for less than, >/= for greater than and equal to, and </= for less than and equal to.
Given that the sum of the three lengths of a fence ranges from 31 to 40 inches, the inequality can be written as:
31 < sum < 40
If two side lengths are 9 and 12 inches, and let x be the third length, the inequality becomes:
31 < 9 + 12 + x < 40
31 < 21 + x < 40
Subtracting 21 at all sides,
31 - 21 < 21 + x - 21 < 40 - 21
10 < x < 19
Hence, the compound inequality to show the length of the third side can be written as 10 < x < 19.

16 less than twice a number is -
10
Answer:
2x-16=10
Step-by-step explanation:
16 less is -16
twice a number is 2x because the number is unknown
Answer: 2n-16= 10
Step-by-step explanation:
Let's break this sentence into parts.
"16 less than": always translates to something -16. Hack: Whenever you see "something less than" you put a subtraction sign and that number on the right side. just like "5 less than" becomes something -5.
'twice a number': 2 times a number's value, or 2 times the number. let's say the number is 4. "twice the number" means to double it's value. 4x2=8. In this case, you write 2n.
- 2n translates to "2 times a number". A number next to a letter means they're being multiplied.
"is 10": =10. Hack: "is" always becomes an equals sign.
Combine
16 less than , twice a number, is 10.
2n - 16= 10
