[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]

If 7x - 4y = 23 and x + y = 8, what is the value of x?
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

Trees are planted on both sides of a road that is 0.28km long. If the trees are planted at intervals of 4m , how many trees were planted?
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

use the rule: y=-3x+2 to find the value of y if x=5
Answer:
y = 13
Step-by-step explanation:
y = 3x + 2
y = - 3 ( 5 ) + 2 ( given :- x = 5)
y = - 15 + 2
y = 13
Answer:
-13
Step-by-step explanation:
y=-3x+2
Let x = 5
y=-3*5+2
= -15+2
= -13

Step-by-step explanation:
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}

Write the equation of the line that passes through the points (-3, - 5) and (-9,3). Express your answer in
simplest y = mx +b form.
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]
Solve the system by Elimination.
y = -2x + 3 and 3y = 2x - 19
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

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

A photo album can hold 8000 photos. Meera put 1000 photos in the album and her sister put 3000 photos. How many more photos can be put in the album?
Answer:
4000
Step-by-step explanation:
A photo album can hold 8000 photos
Meera puts 1000 photos in the album
Her sister puts 3000 photos
= 1000+3000
= 4000
The number of photos that can still be put in the album can be calculated as follows
= 8000-4000
= 4000
