2 * n - 7 <= 40
[tex]2 * n - 7 \leq 40\\n-7\leq 20\\n\leq 27[/tex]
To solve this equation, you need to isolate the variable. The equation is "2 * n - 7 <= 40". First, divide both sides by 40 using the division property of equality. This gets "n - 7 <= 20". Then, to further isolate the variable add 7 to both sides using the addition property of equality. This gets the solution which is, "n <= 27"

The midpoint of FG is (6-4) and the coordinates of point Fare (-3, 6) What are the coordinates of point G?
Answer:
(15,-14)
Step-by-step explanation:
Given that,
The midpoint of FG is (6-4) and the corrdinates of F are (-3,6).
Let (x,y) be the coordinates of point G. Using mid point formula,
[tex]\dfrac{x+(-3)}{2}=6\ \text{and}\ \dfrac{y+6}{2}=-4\\\\x-3=12\ \text{and}\ y+6=-8\\\\x=15,\ \text{and}\ y=-14[/tex]
So, the coordinates of G are (15,-14).

(5x-3)-7(x-2)=2(4x+3)-3(2x-4)+1
Answer:
x = -2
Step-by-step explanation:
5x−3−7(x−2)=2(4x+3)−3(2x−4)+1
5x+−3+(−7)(x)+(−7)(−2)=(2)(4x)+(2)(3)+(−3)(2x)+(−3)(−4)+1(Distribute)
5x+−3+−7x+14=8x+6+−6x+12+1
(5x+−7x)+(−3+14)=(8x+−6x)+(6+12+1)(Combine Like Terms)
−2x+11=2x+19
−2x+11=2x+19
Step 2: Subtract 2x from both sides.
−2x+11−2x=2x+19−2x
−4x+11=19
Step 3: Subtract 11 from both sides.
−4x+11−11=19−11
−4x=8
Step 4: Divide both sides by -4.
−4x /−4 = 8/ −4
x=−2

Line RS intersects triangle BCD at two points and is parallel to segment DC. Triangle B C D is cut by line R S. Line R S goes through sides D B and C B. Lines D C and R S are parallel. width= Which statements are correct? Select three options. △BCD is similar to △BSR. StartFraction B R Over R D EndFraction = StartFraction B S Over S C EndFraction If the ratio of BR to BD is Two-thirds, then it is possible that BS = 6 and BC = 3. (BR)(SC) = (RD)(BS) StartFraction B R Over R S EndFraction = StartFraction B S Over S C EndFraction
Answer:
The correct options are;
1) ΔBCD is similar to ΔBSR
2) BR/RD = BS/SC
3) (BR)(SC) = (RD)(BS)
Step-by-step explanation:
1) Given that RS is parallel to DC, we have;
∠BDC = ∠BRS (Angles on the same side of transversal)
Similarly;
∠BCD = ∠BSR (Angles on the same side of transversal)
∠CBD = ∠CBD = (Reflexive property)
Therefore;
ΔBCD ~ ΔBSR Angle, Angle Angle (AAA) rule of congruency
2) Whereby ΔBCD ~ ΔBSR, we therefore have;
BC/BS = BD/BR → (BS + SC)/BS = (BR + RD)/BR = 1 + SC/BS = RD/BR + 1
1 + SC/BS = 1 + RD/BR = SC/BS = 1 + BR/RD - 1
SC/BS = RD/BR
Inverting both sides
BR/RD = BS/SC
3) From BR/RD = BS/SC the above we have by cross multiplication;
BR/RD = BS/SC gives;
BR × SC = RD × BR → (BR)(SC) = (RD)(BR).
This question is related to properties of similar figures. Therefore, the three statements that are correct are:
ΔBCD is similar to ΔBSR [tex]\frac{BR}{RD}[/tex] = [tex]\frac{BS}{SC}[/tex] (BR)(SC) = (RD)(BS)Two or more figures or shapes are said to be similar if they have all properties in common. This implies angles, orientation and parallel/ perpendicular sides etc.
Comparing the properties of the sketch for the question, the required statements that are correct are:
a. ΔBCD is similar to ΔBSR
b. [tex]\frac{BR}{RD}[/tex] = [tex]\frac{BS}{SC}[/tex]
c. (BR)(SC) = (RD)(BS)
The sketch for the question is attached for better comparison.

a) A shopkeeper sold a mobile set for Rs 9,600 and made a loss of 5%. For what price should he sell it to gain 10 percent
Answer:
Rs 11115.5
Step-by-step explanation:
Selling price =Rs 9600
%loss = cost price - selling price. ×100
cost price.
5 = cost price - Rs 9600 ×100
cost price
Let Cp = cost price
5Cp = 100Cp - Rs 960000
5Cp - 100Cp = - Rs 960000
-95Cp = -Rs 960000
Cp = 960000/95
Cp = Rs 10105
%profit = Sp - Cp ×100
Cp
10 = Sp - 10105 ×100
10105
(10105×10)/100 = Sp - 10105
1010.5 = Sp -10105
Sp = 1010.5 +10105
Sp = Rs 11115.5
Answer:
Rs 10600
Step-by-step explanation:
we can use cross multiplication
95 = 9600
105 = x
95x = 1008000
x=1008000/95
x = 10610.5

Resuelve las siguientes ecuaciones y luego verifica
A-)3x +1=7
B-)2a-2=1+3a
Answer:
A) x=2
B) a=-3
Step-by-step explanation:
La primera ecuación dada es,
A) 3x + 1 = 7
Reste 1 de ambos lados, tenemos
3x +1-1=7-1
[tex]\Rightarrow 3x=6[/tex]
Dividir por 3 (ya que 3 es un número distinto de cero) de ambos lados, tenemos
[tex]\frac{3x}{3}=\frac {6}{3}[/tex]
[tex]\Rightarrow x=2[/tex]
Ahora, compruebe si x = 2 es la solución correcta o no.
El lado izquierdo de la ecuación dada es 3x + 1.
Ponga x = 2, tenemos
[tex]3\times2+1=7[/tex]
Que es igual al lado derecho de la ecuación dada.
Por tanto, x = 2 es la solución correcta.
La segunda ecuación es
B) 2a-2=1+3a
Reste 3a de ambos lados, tenemos
2a-2-3a=1+3a-3a
[tex]\Rightarrow -a-2=1[/tex]
Suma 2 de ambos lados, tenemos
-a-2+2=1+2
[tex]\Rightarrow -a=3[/tex]
Multiplica por -1 (como -1 es un número distinto de cero) de ambos lados, tenemos
[tex]-a\times (-1)=3\times(-1)[/tex]
[tex]\Rightarrow a=-3[/tex]
Ahora, verifique si a = -3 es la solución correcta o no
El lado izquierdo de la ecuación dada es 2a-2.
Ponga a = -3, tenemos
[tex]2\times(-3)-2=-8[/tex]
El lado derecho de la ecuación dada es 1 + 3a.
Ponga a = -3, tenemos
[tex]1+3\times(-3)=-8[/tex].
Aquí, al poner a = -3, el valor del lado izquierdo es igual al valor del lado derecho.
Por tanto, a = -3 es la solución correcta.

What is congruency?In geometry, two figures or objects are said to be congruent if their shapes and sizes match, or if one is the mirror image of the other. The meaning of congruency is that the two shapes are similar as well as equal in size.
Given that WH is the bisector of line OY and cutting OY at point H.
The two triangles formed are WHO and WHY
Side WO ( Side WY )
WH = WH ( common side )
OH = HY ( Cut by the bisector equally)
It can be seen that the three sides of the triangle are equal the triangle WHO and WHY both are equal by side-side-side property of the congruency.

Which expression is equivalent to 18 - 7?
Apex
Answer: See explanation
Step-by-step explanation:
Your question isn't complete but let me help out.
To get an expression that is equivalent to 18 - 7, you will have to know the value of 18-7 first. This will be:
= 18 - 7
= 11
Since we know that 18-7 = 11, then from the options that you're given, you'll find the one that is also equal to 12 which will be the answer.
For example, let's say you're given the options of a. 20 - 6 and b. 3 + 19 - 11.
20 - 6 = 14. This means that it isn't an equivalent of 18-7.
3+19-11 = 11. So, this is an equivalent of 18-7.

what is more precise 13.2 feet or 8.14 feet.
Answer:
8.14 feet
Step-by-step explanation:
8.14 feet will be more precise because it measures to the hundredths place, while 13.2 feet only measures to the tenths place.
Measuring to smaller place values increases precision and accuracy because the measurements are more likely to be more exact and correct.
So, 8.14 feet is more precise

Consider the function f ( ) round( ) x x , which rounds the input, x, to the nearest integer. Is this function
one-to-one? Explain or justify your answer.
please help
Answer:
The function is not one-to-one
Step-by-step explanation:
Required
Determine if [tex]f(x) = round(x)[/tex] is one-to-one
To answer this question, we need to make use of illustrating values of x.
Take x = 6.7
This implies that:
[tex]f(6.7) = round(6.7)[/tex]
[tex]f(6.7) = 7[/tex]
Also, Take x = 6.8
[tex]f(6.8) = round(6.8)[/tex]
[tex]f(6.8) = 7[/tex]
Notice that the above values of x give the same resulting value of f(x).
If you also take x = 7.4
[tex]f(7.4) = round(7.4)[/tex]
[tex]f(7.4) = 7[/tex]
This also gives the same value as the (2) illustration previously used
With these illustrations, we've seen that f(x) has the tendency to have more than one values for different values of x.
Hence:
The function is not one-to-one
