Answer:
JK = 42 , KL = 78
Step-by-step explanation:
JK + KL = JL , substitute values
4x + 6 + 7x + 15 = 129 , that is
11x + 21 = 120 ( subtract 21 from both sides )
11x = 99 ( divide both sides by 11 )
x = 9
Then
JK = 4x + 6 = 4(9) + 6 = 36 + 6 = 42
KL = 7x + 15 = 7(9) + 15 = 63 + 15 = 78

If EF=2x−12, FG=3x−15, and EG=23, find the value of FG
Answer:
FG= 15
Step-by-step explanation:
2x-12+3x-15=23
5x-27=23
-27+27 23+27
5x=50
5x/5=50/5
x=10
FG= 3x-15
3(10)-15
30-15
FG=15
Find the value of x.
Step-by-step explanation:
the sum of all angles in a triangle is always 180 degrees.
so,
x + 12 + 2x - 29 + x + 5 = 180
4x - 12 = 180
4x = 192
x = 48
The sum of 6 times a number 3 and 9
is .
Step-by-step explanation:
28 is the answer because you multiply 6×3 and it is equal to 18 and add 8 is equal to 28
solve the inequality. -8c - 9 < -17
Answer:
it would be c >1

Answer:
everbody help this guy
Step-by-step explanation:
X = ?
Can someone tell me
The answer to this question
Answer:
113=x
Step-by-step explanation:
seeing as how the sum of all angles in a triangle is 180 degrees, we can get an equation:
28+39+x=180
simplify to get:
67+x=180
subtract 67 from both sides to get your answer:
113=x
Answer:
[tex]x=113[/tex]
[tex]y=67[/tex]
[tex]z=49[/tex]
Step-by-step explanation:
To find x:
We can use the angle sum property of a triangle which states that, The sum of all internal angles of a triangle is always equal to 180°.
Therefore, [tex]28+39+x=180[/tex]
[tex]67+x=180[/tex]
[tex]x=180-67[/tex]
[tex]x=113[/tex]
Now that we know the value of [tex]x[/tex] we can use it to find the value of [tex]y[/tex].
We can see that angle [tex]x[/tex] and [tex]y[/tex] are supplementary which means:
[tex]x+y=180[/tex]
[tex]113+y=180[/tex]
[tex]y=180-113[/tex]
[tex]y=67[/tex]
Now that we know the value of [tex]y[/tex] we can use the angle sum property of a triangle again:
[tex]64+y+z=180[/tex]
[tex]64+67+z=180[/tex]
[tex]131+z=180[/tex]
[tex]z=180-131[/tex]
[tex]z=49[/tex]

A family room has a circular rug with a diameter of 4 meters. What is the rug's circumference? Use 3.14 for . meters
If the radius of one circle is 4cm and the diameter of another circle is 12cm, what is the ratio
of circumferences for the small circle to the bigger circle?
Answer:
2 cm/3 cm
Step-by-step explanation:
Diameter of smaller circle = 8cm
Diameter of bigger circle = 12 cm
8cm/12cm = 2/3
A pair of skate blades costs
$189.00. A pair of skate boots
costs 4 times that much. How
much are the skates and blades
all together?
Answer:
$945.00
Step-by-step explanation:
Use (189*4)+189 or 189*5 to solve:
189*4= 756
759+189= 945
189*5= 945

Step-by-step explanation:
Please help me !! Marking brainliest
Which number is the greatest?
A the square root of 125
B the whats root of 30
Answer:
B) √(30)
Step-by-step explanation:
A: The cube root of 125 is 5 because 5^3, or 5 × 5 × 5, equals 125.
B: The square root of 30 is between the numbers 5 and 6, meaning 30 is between 25 and 36. The square root of 30 is about half-way in between 5 and 6, so we can say √(3) ≈ 5.5
Now, when we compared 5.5 and 5, 5.5 is obviously greater. Therefore, the correct answer is B √(30).
State the domain and any values that are excluded from the domain of the function.
f(x) = 2x-5/x-4
I give Brainliest!
Answer:
see explanation
Step-by-step explanation:
f(x) = [tex]\frac{2x-5}{x-4}[/tex]
The denominator cannot equal zero as this would make f(x) undefined.
Equating the denominator to zero and solving gives the value that x cannot be
x - 4 = 0 ⇒ x = 4 ← excluded value
Domain is x ∈ R , x ≠ 4
someone please explain how to do the last one. I don’t want the answer, i just need to learn how to do it:) please help with m
Answer:
m∠y = 50 (Due to A)
m∠x = 50 (Due to F)
Step-by-step explanation:
Due to corresponding angles,
x = y = 50
Also, another thing... You wrote 60 degrees as your answer for the first part, you did a slight miscalculation.
180 - 130 = 50
So the answer for the first part is 50 degrees. However, the reasoning is correct!

Denise bought a T-shirt at the sale price of $21.08. This represents a 15% decrease in price. What was the original price of the shirt?
Answer:
100% - 15 % = 85 %
So, $21.08 represents the 85% sale price
What number represents the other 15% of the original price?
(21.08 x 15) / 85 = 3. 72
$21.08 + $3.72 = $24.80 which is the original price.
Step-by-step explanation:
a circle’s radius is increased by 8%. Find the increase in the circle’s area.
Answer: The percentage increase in the area of the circle is 16.64 % when radius is increased by 8 %.
Order the number \pi ,3, and \sqrt(11 )from least to greatest
Firstly, let's write these out to help us see:
[tex]\pi[/tex] = 3.1415
3
[tex]\sqrt{11}[/tex] = 3.3166
We can see that [tex]\sqrt{11}[/tex] is 0.3166 greater than 3, and 0.1751 greater than pi. Therefore, it's the biggest number.
Pi is second biggest because it is less than [tex]\sqrt{11}[/tex] but greater than 3.
Therefore, your order would be:
3, [tex]\pi[/tex], [tex]\sqrt{11}[/tex]
Hope this helps! :)

Answer:
- 5 [tex]\frac{1}{3}[/tex]
Step-by-step explanation:
- 3 [tex]\frac{1}{2}[/tex] - 1 [tex]\frac{5}{6}[/tex] ( change to improper fractions )
= - [tex]\frac{7}{2}[/tex] - [tex]\frac{11}{6}[/tex] ( multiply numerator/denominator of first fraction by 3 )
= - [tex]\frac{7(3)}{2(3)}[/tex] - [tex]\frac{11}{6}[/tex]
= - [tex]\frac{21}{6}[/tex] - [tex]\frac{11}{6}[/tex]
= [tex]\frac{-21-11}{6}[/tex]
= [tex]\frac{-32}{6}[/tex]
= - [tex]\frac{32}{6}[/tex]
= - 5 [tex]\frac{2}{6}[/tex]
= - 5 [tex]\frac{1}{3}[/tex]
