Answer:

[tex]\text{B. }26}[/tex]

Step-by-step explanation:

Since [tex]\overline{PN}[/tex] and [tex]\overline{PQ}[/tex] are equal, we can set them equal to each other:

[tex]7x+5=10x-4,\\9=3x,\\x=3[/tex]

Substitute [tex]x=3[/tex] to solve for [tex]\overline{PQ}[/tex]:

[tex]\overline{PQ}=10(3)-4=\boxed{\text{B. }26}}[/tex]

Answer:

x=5

Step-by-step explanation:

7x - 4y = 23 and x + y = 8

Multiply the second equation by 4

4x + 4y = 32

Add this to the first equation

7x - 4y = 23

4x + 4y = 32

------------------------

11x    = 55

Divide each side by 11

11x/11 = 55/11

x = 5

Answer:

[tex]\huge\boxed{x=5}[/tex]

Step-by-step explanation:

[tex]\left\{\begin{array}{ccc}7x-4y=23\\x+y=8&|\text{subtract}\ x\ \text{from both sides}\end{array}\right\\\left\{\begin{array}{ccc}7x-4y=23&(1)\\y=8-x&(2)\end{array}\right\\\\\text{substitute (2) to (1):}\\\\7x-4(8-x)=23\qquad|\text{use the distributive property}\\\\7x+(-4)(8)+(-4)(-x)=23\\\\7x-32+4x=23\qquad|\text{combine like terms}\\\\(7x+4x)-32=23\qquad|\text{add 32 to both sides}\\\\11x-32+32=23+32\\\\11x=55\qquad|\text{divide both sides by 11}\\\\\dfrac{11x}{11}=\dfrac{55}{11}\\\\x=5[/tex]

Answer:

x = 3.5 and y = -4

Step-by-step explanation:

Solve by elimination by adding the two equations together:

y = -2x + 3

3y = 2x - 19

Add like terms, which will eliminate the x values:

4y = -16

Divide each side by 4:

y = -4

Plug in -4 as y into one of the equations, and solve for x:

y = -2x + 3

-4 = -2x + 3

-7 = -2x

3.5 = x

So, x = 3.5 and y = -4

that's the answer

Step-by-step explanation:

[tex]slope = \frac{y2 - y1}{x2 - x1} \\ = \frac{3 - - 5}{ - 9 - - 3} = \frac{8}{ - 6} \\ \frac{y - 3}{x - - 9} = \frac{8}{ - 6} \\ - 6(y - 3) = 8(x - - 9) \\ - 6y + 18 = 8x + 72 \\ - 6y = 8x + 72 -18 \\ - 6y = 8x + 54 \\ \frac{ - 6y}{ - 6} = \frac{8x}{ - 6} + \frac{54}{ - 6} \\ y = \frac{8x}{ - 6} - 9 [/tex]

Answer:

if this was a equation you would first subtract 12 from the other number then divide it by 3

Answer:

3(x+4)

Step-by-step explanation:

Check 3(x+4), when you use the distributive property, you get 3x + 12, so this is correct. (sorry, I'm really bad at explaining...)

There is no AAA congruency

The are no right angle marked on diagram so, no HL

There are vertical angles and the parallel lines create congruent Alternate Interior Angles

Answer:

II and III

Step-by-step explanation:

In ΔSRT & ΔVUT

∠STR = ∠VTU   {Vertically opposite angles}

RT = UT   {Given}

∠SRT = ∠VUT           {UV //RS and UR is transversal; alternate interior angles}

ΔSRT ≅ ΔVUT              {A S A congruent}

In ΔSRT & ΔVUT

∠RST = ∠UVT           {UV //RS and SV is transversal; alternate interior angles}

∠SRT = ∠VUT           {UV //RS and UR is transversal; alternate interior angles}

RT = UT   {given}

ΔSRT ≅ ΔVUT      {A  A S congruent}

Answer:

x = 56

Step-by-step explanation:

DAR is a straight line so it equals 180 degrees

DAB + BAC + CAF = DAF

64+ x+60 = 180

Combine line terms

124+x =180

x = 180-124

x = 56

Answer:

I think its y^-3

Step-by-step explanation:

Since y^-3/y^-2 are both negatives they would swap places to become positive - y^2/y^3

then using rules of exponents you would subtract the exponents witch would be y^-3

Answer:

[tex]\frac{1}{y^{3} }[/tex]

Step-by-step explanation:

[tex]\frac{y^{-5}}{y^{-2}}[/tex]

Apply exponent rule [tex]\frac{x^a}{x^b}=x^{a-b}[/tex]

[tex]=y^{-5-\left(-2\right)}[/tex]

Apply rule [tex]-\left(-a\right)=a[/tex]

[tex]=y^{-5+2}[/tex]

Add/Subtract the numbers -5+2=-3

[tex]=y^{-3}[/tex]

Apply exponent rule [tex]a^{-b}=\frac{1}{a^b}[/tex]

[tex]=\frac{1}{y^3}[/tex]

In the diagram below, ΔABC ≅ ΔDEF. Therefore, by CPCT, ∠B = ∠E.

Corresponding parts of congruent triangles or CPCT is used to denote the relation between the sides and the angles of two congruent triangles.

Since, ΔABC ≅ ΔDEF,

AB = DE

BC = EF

AC = DF

∠A = ∠D

∠B = ∠E

∠C = ∠F

Step-by-step explanation:

Answer:

140 trees

Step-by-step explanation:

Number of trees planted on one side of the road = length of the road / intervals

1000m = 1km

0.28 x 1000 = 280m

280 / 4 = 70

number of trees planted on both sides of the roads = 70 x 2 = 140 trees
