[tex]here \: c \: is \: the \: \: mid \: point \\ so \: bc = cd \\ 6x - 16 = 4x + 10 \\ x \: terms \: togather \\ 6x - 4x = 10 + 16 \\ 2x = 26 \\ x = \frac{26}{2} \\ x = 13 \\ thank \: you[/tex]
Answer:
x=13
Step-by-step explanation:
BC = CD
6x-16 = 4x+10
Subtract 4x from each side
6x-16-4x = 4x+10-4x
2x-16 = 10
Add 16 to each side
2x-16+16 = 10+26
2x = 26
Divide by 2
2x/2 =26/2
x = 13
Line segment JM has endpoints with coordinates 0 and 25 on a number line. Points K and L are on segment JM. K has a coordinate of 5 and point L has a coordinate of 12. Find the probability that a point on JM is placed first on JL and a second point is not placed on KL.
Answers
Answer:
D. 216/625Step-by-step explanation:
The length of the segment JM is 25 units.The segment JL is between 0 and 12, so is 12 units.The segment KL is between 5 and 12, so is 7 units.The probabilities for each point:
P(point on JL) = 12/25P(point not on KL) = 1 - 7/25 = 18/25Required probability:
P = 12/25*18/25 = 216/625Correct choice is D
15 people fit comfortably in a 6 feet by 6 feet area. Use this value to estimate the size o a crowd that is 30 feet deep on both sides of the street along a 2-mile section of a parade route. (Hint: 1mile= 5,280ft)
Answers
158,400 people will fit into an area with a dimension of 30feets by 2 miles.
The area of the street can be calculated thus :
Area = Length × width
Converting the width to feets :
1 mile = 5280 feets
2 miles = x
Cross multiply :
x = 5280 × 2 = 10560 feets
Area = 10560 ft × 30ft = 316800 ft²
Since 15 people fit into an area with dimension which is 6 ft by 6ft
Area = 6 × 6 = 36 ft²
Let x = number of people
15 people = 36 ft²
x people = 316800 ft²
Cross multiply :
x = (316800 × 15) / 36
x = 158,400 people
Hence 158,400 people will fit in.

What is the value of U. 51degrees, 79degrees and u.
Answers
Hi ;-)
[tex]u+51^o=79^o\\\\u=79^o-51^o\\\\\huge\boxed{u=28^o}[/tex]
The required equation is,
→ 51° + U = 79°
Now we should,
find the required value of U.
→ 51° + U = 79°
→ U = 79° - 51°
→ [U = 28°]
Let's check whether the required value of U is correct or incorrect,
→ 51° + U = 79°
→ 51° + 28° = 79°
→ 79° = 79°
→ LHS = RHS
Hence, 28° is the required value of U.

Find the value of x.
Answers
Answer:
Step-by-step explanation:
Those two angles are equal. They are corresponding angles. In two parallel lines crossed by a transversal. 8 angles are produced. 4 have one value and the other 4 are supplementary to the first four.
These 2 are part of the first group of 4.
So 12x - 8 = 104
12x - 8 + 8 = 104 + 8
12x = 112
x = 9 1/3

7.65%*459=35.1135
459-28.6875=430.3125

Answers
Answer:
x=11

Step-by-step explanation:
(9x+25)=(13x-19)
9x+25 = 13x−19
9x+25-25 = 13x−19-25
9x=13x-44
9x-13x=13x-44-13x
-4x= -44
x=11
y= 180-(9x+25)
y= 180-(99+25)
y= 180-124 = 56
y= 56-5 = 51
y= 51/17

In this question, you are finding the square root of 100-84.
The first thing you should do is do whatever is inside the square root sign. So, do 100-84:
100-84= 16
Now, you can take the square root of that number. Taking the square root means which number, when multiplied by itself, equal the number under the square root sign? In this case, the answer is 4!
This is because 4 multiplied by itself ( 4 times 4) is 16!
