8th grade math pls help and show work i’ll give brainliest
Answer:
B) -8
Step-by-step explanation:
Slope is rise/run, or the difference in y over the difference in x, so to solve this:
Take the y value of one of the points and subtract it from the other, and divide it by the same thing with the x values
[tex]\frac{9-1}{6-7} =\frac{8}{-1} =-8[/tex]

Tomás bought a book that cost $18. It was on sale for 84% of its original price. How much did Tomás pay?
Answer:
I dont know lol
Step-by-step explanation:
I
dont
know
lol
Answer: $15.12
Step-by-step explanation:
You just need to find 84% of 18 which is 15.12. what you do is you convert the percent into 0.84 and multiply is by the original price which is 18.
84%=0.84
0.84 times 18 = 15.12

Which statement is true about the following pair of rectangles?
Two rectangles are shown. To the left, a larger rectangle has a lower side labeled 60 centimeters and a left side labeled 30 centimeters. To the right, a smaller rectangle has an upper side labeled 6 centimeters and a right side labeled 3 centimeters.
A. They are not similar because Start Fraction 6 over 60 End Fraction≠ Start Fraction 30 over 3 End Fraction.
B. They are not similar because Start Fraction 30 over 3 End Fraction = Start Fraction 60 over 6 End Fraction.
C. They are not similar because Start Fraction 3 over 6 End Fraction ≠ Start Fraction 30 over 60 End Fraction.
D. They are similar because Start Fraction 3 over 6 End Fraction = Start Fraction 30 over 60 End Fraction.
Answer:
Option D
Step-by-step explanation:
the height of the first rectangle ( 30 ) over the height of the other rectangle ( 3 ) is 30/3 and equals 10
the length of the first rectangle ( 60 ) over the length of the second rectangle ( 6 ) is 60/6 and equals 10
the ratio of the sides of both rectangles are equivalent therefore the are similar
Hiiiooo!! Could someone please help me out with this❤️❤️❤️

which of the following is NOT a characteristic of a parallelogram
Answer:
If all the points do not connect then you do not have a parallelogram. If all of the sides are not of equal length, them being parallel than this is not a parallelogram. Opposite edges and angles have to be congruent for it to be a parallelogram.

Which of the following equations is true to find the length BC?
Answer:
BC/sin 23 = 10/sin 47
Step-by-step explanation:
Here, we want to select the true equation to find the length BC
From the question, we have the angle facing side BC; also, we have the angle and the side facing it for another side
In this situation, the best way to solve for BC is by the use of the sine rule
The sine rule states that the ratio of the length of a side and the sine of the angle facing the side is constant for a given triangle
Thus, we have it that;
BC/sin 23 = 10/sin 47
If 1432x-3 = 143x+1, then...
Answer: x= 4/1289 not sure if this was what you were looking for.
Step-by-step explanation:
Step 1: Subtract 143x from both sides.
1432x−3−143x=143x+1−143x
1289x−3=1
Step 2: Add 3 to both sides.
1289x−3+3=1+3
1289x=4
Step 3: Divide both sides by 1289.
1289x/1289 = 4/1289
x= 4/1289
find the area of the following triangle and write your result in the empty box
Answer:
Step-by-step explanation:
Area = 1/2bh
since b = 10in and height = 6in
then
1/2 x 10 x 6
= 30
Answer:
Area = 1/2bh since b = 10in and height = 6in next you do 1/2 x 10 x 6 = 30
n-6=2n-n
pls help solve :)
Answer:eorder the terms:
-6 + n = 2n + -1n
Combine like terms: 2n + -1n = 1n
-6 + n = 1n
Solving
-6 + n = 1n
Solving for variable 'n'.
Move all terms containing n to the left, all other terms to the right.
Add '-1n' to each side of the equation.
-6 + n + -1n = 1n + -1n
Combine like terms: n + -1n = 0
-6 + 0 = 1n + -1n
-6 = 1n + -1n
Combine like terms: 1n + -1n = 0
-6 = 0
Add '6' to each side of the equation.
-6 + 6 = 0 + 6
Combine like terms: -6 + 6 = 0
0 = 0 + 6
Combine like terms: 0 + 6 = 6
0 = 6
Simplifying
0 = 6
Combine like terms: 0 + -6 = -6
-6 = 6 + -6
Combine like terms: 6 + -6 = 0
-6 = 0
Step-by-step explanation:
Answer:
-6 = 0n
Step-by-step explanation:
n - 6 = 2n - n
n - 6 = n
-n -n
-6 = 0n
I think you might have left something out but this is the answer for the equation you posted. Please let me know if there are more exponents or factors I am missing!
What is the measure of the missing angle
Answer:
41°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
let x be the missing angle, then sum the angles and equate to 180°, that is
87° + 52° + x = 180°
139° + x = 180° ( subtract 139° from both sides )
x = 41°
Find the sum of the interior angles of a regular 14-gon.
9514 1404 393
Answer:
2160°
Step-by-step explanation:
The sum of interior angles of a convex n-gon is ...
angle sum = 180(n -2)°
When n=14, the angle sum is ...
angle sum = 180(14 -2)° = 2160°

Answer:
Area of sector ≈ 15.6π (nearest tenth)
Step-by-step explanation:
Given:
radius = 5 cm
Central angle in radians = ∅ = 5π/4
Required:
Area of the sector
Solution:
Area of sector = ½*r²*∅
Plug in the values into the formula
Area of sector = ½*5²*5π/4
= ½*25*5π/4
= 12.5*5π/4
= (12.5*5π)/4
Area of sector = 15.625π ≈ 15.6π (nearest tenth)
