The number of students, n that possibly eat lunch at school, n = 531 or more students.
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Given that the number of students who bring lunch is 45 fewer these the number of students who eat the school lunch. There are more than 485 students who bring lunch.
The number of students who bring lunch, is;
B > 485 students
The number of student who eat lunch in school, E = B + 45
Thus, E > 485 + 45
The number of student that possibly eat lunch in school, E > 530 students.
The number of students, n that possibly eat lunch at school, n = 531 or more students.

write an equation in slope intercept form for all these below
14.through: (5, 1) slope=3/5
15. through:(2, -4) slope=-1
17. through:(5,-2) and (-5,3)
Answer:
14. y= 3/5x-2
15. y= -1x-2
17. -1/2
Step-by-step explanation:
Since you have a point and a slope put it in point-slope form first.
Point-slope form: y-y1=m(x-x1)
Then solve for y.
Then you'll get the slope-intercept form.
For number 17 use the slope-intercept form y=mx+b
rise/run= m= y2-y1/x2-x1

Step-by-step explanation:
Let the unknown number be x.
8 = -4(1) + x
8 = -4 + x
x - 4 = 8
x = 8 + 4
x = 12
Answer:
[tex]a_{n}[/tex] = - 4n + 12
Step-by-step explanation:
The n th term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 8 and d = a₂ - a₁ = 4 - 8 = - 4 , then
[tex]a_{n}[/tex] = 8 - 4(n - 1) = 8 - 4n + 4 = - 4n + 12
Plz l need the answer, If zero lies between a and d, give one set of possible answers for a, b, c, and d.
Answer:
a= -1, b=0, c=1, d=10
Step-by-step explanation:
You are given a.......0.........d
a= -1, b=0, c=1, d=10
A snack mix recipe calls for 1 1/2 cups of dip and 1/3 cup of vegetables. Cole wants to make the same recipe using 1 cup of vegetables. How many cups of dip will cole need.
Answer:
4 1/2 cups of dipStep-by-step explanation:
Let required amount be x
Using the ratio to find x:
1 1/2 ÷ x = 1/3 ÷ 1x = 1 1/2 × 3x = 3/2×3 x = 9/2 x = 4 1/2 cupsGrant spent half of his weekly allowance. Then he earned $5 back by doing the dishes. What is his weekly allowance if he ended with $15?
Answer:
Grant's weekly allowance is $20.
Step-by-step explanation:
We know that Grant ended with $15. We can say that Grant's weekly allowance is x.
x/2 + 5 = 15
Now to solve:
x/2 + 5 - 5 = 15 - 5 (subtract 5 from both sides to isolate the x/2)
x/2 = 10
x/2 * 2 = 10 * 2 (multiply both sides by 2 to isolate the x)
x = 20
Grant's weekly allowance is $20.
Does anyone know how to do these? I don't understand them at all... :(
Answer:
For the first 2 questions, you need to find the square roots of those numbers. The second 2 question, you need to do those problems. Remember that absolute value is always positive. Then, plot those numbers on the coordinate plain.

Answer: 6 (z+13)
Step-by-step explanation:
Answer:
Step-by-step explanation:
10-z=6
We move all terms to the left:
10-z-(6)=0
We add all the numbers together, and all the variables
-1z+4=0
We move all terms containing z to the left, all other terms to the right
-z=-4
z=-4/-1
z=+4
The hanger image below represents a balanced equation.
a
9.1
4
Write an equation to represent the image.
Answer:
9.1 = a+4
Step-by-step explanation:
The right side has two different values, variable a, constant 4.
The left side has the constant 9.1.
If both sides are equal, then
a + 4 should equal 9.1
Answer:
9.1 = a+4

suppose the fee is 7.5% of the selling price. determine the total cost of the game(fee included) original cost of the game is $76.
show your work
Answer:
Original Cost: $76
Fee: 7.5%
Take 7.5% of 76 (76 times .075) and add the result to the original amount $76
So, 76 times .075= 5.7
5.7+76= 81.7

Answer:
Area of rectangular garden = lxb = 10*5
= 50 sq. inch
when area increases by six times
new area = 50*6 = 300 sq inches
now,
let x be increasement in both length and width
(5+x) (10+x) = 300
50 + 5x + 10x + x² = 300
x² + 15x - 250 = 0
x²+ 25x-10x -250 = 0
x(x+25) - 10 (x+25) = 0
( x-10) (x+25) = 0
either x + 25 =0
x = -25 length can be negative
0r x-10 = 0
x = 10
so 10 inches is increase on both side
Step-by-step explanation:
Solve for x.
4(1 - x) + 2 x = -3(x + 1)
To make 1 batch of vegetable soup, Sam needs 16 ounces of water and 8 ounces of vegetables. How does the amount of water compare to the amount of vegetables?
Answer:
There is two ounces of water for every ounce of vegetables.
Step-by-step explanation:
Given that:
Sam needs 16 ounces of water and 8 ounces of vegetables to make 1 batch of vegetable soup.
Ratio is defined as the quantitative relation between two numbers.
We will use ratio to compare the amount of water to amount of vegetables.
Ratio of water to vegetables
16 : 8
Dividing by 8
[tex]\frac{16}{8}:\frac{8}{8}[/tex]
2:1
Hence,
There is two ounces of water for every ounce of vegetables.

a student earned a grade of 80% on a math test that had 20 problems how many problems on this test did the student answer correctly
Answer:
16
Step-by-step explanation:
To find 80% of 20, multiply .80 x 20
.80×20 = 16
This is how you multiply percentages--put the decimal point 2 places to the left, then multiply. In this case, you're looking at 80%, so move the decimal point two places to the left
80.0 becomes .80
Then multiply that by the number you're trying to find the percentage of

Answer:
The inequality [tex]\frac{8}{4}\:<\frac{5}{2}\:[/tex] is true.
Step-by-step explanation:
Given
[tex]\frac{8}{5}<\frac{9}{10}[/tex]
FALSE
Reason: 8/5 or 1.6 is greater than 9/10 or 0.9
[tex]1>\frac{6}{5}[/tex]
FALSE
Reason: 1 is smaller than 6/5 or (1.1)
[tex]\frac{5}{2}<2\frac{1}{2}[/tex]
converting mixed number to improper fraction
[tex]\frac{5}{2}<\frac{5}{2}[/tex]
FALSE
Reason: 5/2 can not be less than 5/2
[tex]\frac{8}{4}\:<\frac{5}{2}\:[/tex]
[tex]2<\frac{5}{2}[/tex]
TRUE
Reason: 2 is indeed smaller than 5/2 or 5.2 ∵ 5/2 = 2.5
Therefore, inequality [tex]\frac{8}{4}\:<\frac{5}{2}\:[/tex] is true.

work out the value of x
will give brainliest
Answer:
x = 35
Step-by-step explanation:
we know that all triangles add up to 180
you first need to make an expression in which the angles equal 180
105 + 140 + x = 180
145 + x = 180
subtract 145 from both sides
x = 35
