School rules permit no fewer than 2 teachers per 25 students. There are at least 245 students enrolled in the school. If x represent teachers and y represents students, which system of linear inequalities can be used to determine the possible number of teachers and students at the school?
2y ≥ 25x and y ≥ 245
2y ≤ 25x and y ≥ 245
25y ≤ 2x and y ≥ 245
25y ≥ 2x and y ≥ 245
Answers
Answer:
(b) 2y ≤ 25x and y ≥ 245
Step-by-step explanation:
You want the teacher/student ratio to be at least 2/25, so ...
x/y ≥ 2/25
25x ≥ 2y . . . . . multiply by 25y
2y ≤ 25x . . . . . swap sides to get the form used in answer choice B
The other inequality says the number of students is at least 245:
y ≥ 245
Answer:
B- 2y ≤ 25x and y ≥ 245

what statement makes the open sentence 12 + 3x = 30 true?MUTIPLE CHOICE QUESTION WILL MARK BRAINLIEST
(x=2), (x=4), (x=5), (x=6)
Answers
Answer:
x= 6
Step-by-step explanation:
12+3x=30
3x+12=30
3x+12-12=30-12
3x=30-12
3x=18
3x divided by 3 = 18 divided by 3
x=18 over 3
18 divided by 3 is 6
x=6
Answer:
x = 6
Step-by-step explanation:
12 +3x = 30
Subtract 12 from both sides
3x = 30 - 12
3x = 18
Divide both side by 3
x = 18/3
x = 6

x= -2/7
Hi there! :)
12=2(7x+8)
Use the Distributive property:
12=14x+16
Move all the numbers to the right side and the variables to the left side:
-14x=16-12
-14x=4
Divide both sides by -14 to isolate x:
x=[tex]-\frac{4}{14} \\-\frac{2}{7}[/tex]

The following ratio gives us a unit rate of 2 feet per second.
Fill in the missing number in the ratio.
?/10 foot : 1/4 second
Answers
Step-by-step explanation:
2 ft / 1 second
and now
x/10 foot / 1/4 second
we need to multiply the original ratio by 1/4 to get the same denominator :
2/1 × (1/4)/(1/4) = (2/4) / (1/4) = (1/2) / (1/4)
how many 10th foot are 1/2 ?
we need to bring 1/2 to the denominator of 10.
1/2 = x/10
10 = 2x
x = 5
so, 1/2 = 5/10
therefore, or answer is

Step-by-step explanation:
Let the number be 'x'
[tex]\dfrac{x}{6}-10=2\\\\\\Add \ 10 \ to \ both \ sides\\\\\\\dfrac{x}{6}=2+10\\\\\\\dfrac{x}{6}=12\\\\Multiply \ both \ side \ by 6\\\\\\x=12*6\\\\x=72[/tex]

[tex]\dfrac{1}{7}+x=\dfrac{2}{3}x\\\\\\x - \dfrac{2}{3}x=\dfrac{-1}{7}\\\\\\\dfrac{3}{3}x-\dfrac{2}{3}x=\dfrac{-1}{7}\\\\\\\dfrac{1}{3}x=\dfrac{-1}{7}\\\\\\\x=\dfrac{-1}{7}*3\\\\\\x=\dfrac{-3}{7}[/tex]
3)-3(v + 25) = 111
Use distributive property
-3v + (-3)*25 = 111
-3v - 75 = 111
Add 75 to both sides
-3v = 111+ 75
-3v = 186
Divide both sides by (-3)
v = 186/(-3)
v = -62

Q1. For each of the following values of a,b and c, where
(a) a = -20, b = -10, c = 5
(b) a = -40, b = 10, c = -5
Show that:
(i) a÷b ≠ b÷a
(ii) (a÷b)÷c ≠ a÷(b÷c)
(iii) a÷(b+c)≠(a÷b)+(a÷c)
Answers
Explanation:-
⟨a⟩Given that
a = -20
b = -10
c = 5
⟨i⟩ LHS = a÷b
⇛ -20÷-10
⇛ -20/-10
⇛ 2
and
RHS = b÷a
⇛ -10÷-20
⇛ -10/-20
⇛ 1/2
LHS ≠ RHS
a÷b ≠ b÷a
⟨ii⟩
LHS = (a÷b)÷c
⇛ (-20÷-10)÷5
⇛ 2÷5
⇛ 2/5
RHS = a÷(b÷c)
⇛ -20÷(-10÷5)
⇛ -20÷-2
⇛ -20/-2
⇛ 10
LHS ≠ RHS
(a÷b)÷c ≠ a÷(b÷c)
⟨iii⟩ LHS = a÷(b+c)
⇛ -20÷(-10+5)
⇛ -20÷(-5)
⇛ -20/-5
⇛ 4
RHS = (a÷b)+(a÷c)
⇛ (-20÷-10)+(-20÷5)
⇛ 2+(-4)
⇛ 2-4
⇛ -2
LHS ≠ RHS
a÷(b+c) ≠ (a÷b)+(a÷c)
⟨b⟩.Given that
a = -40
b = 10
c = -5
⟨i⟩ LHS = a÷b
⇛ -40÷1
⇛ -40/1
⇛-40
and
RHS = b÷a
⇛ 10÷-40
⇛ 10/-40
⇛ -1/4
LHS ≠ RHS
a÷b ≠ b÷a
⟨ii⟩.
LHS = (a÷b)÷c
⇛ (-40÷10)÷-5
⇛ -4÷-5
⇛ 4/5
RHS = a÷(b÷c)
⇛ -40÷(10÷-5)
⇛ -40÷-2
⇛ -40/-2
⇛ 20
LHS ≠ RHS
(a÷b)÷c ≠ a÷(b÷c)
⟨iii⟩ LHS = a÷(b+c)
⇛ -40÷(10-5)
⇛ -40÷(5)
⇛ -40/5
⇛ -8
RHS = (a÷b)+(a÷c)
⇛ (-40÷10)+(-40÷-5)
⇛ (-4)+8
⇛ 8-4
⇛ 4
LHS ≠ RHS
a÷(b+c) ≠ (a÷b)+(a÷c)

Which value of x makes the equation 1.25 (4x-10) = 7.5 true
Answers
Answer:

Step-by-step explanation:
1.25(4x - 10) = 7.5
~Use the distributive property
5x - 12.5 = 7.5
~Add 12.5 to both sides
5x = 30
~Divide 5 to both sides
x = 6
