Answer:
<ABD = 44
<DBC = 44
<ABC = 88
Step-by-step explanation:
If an angle bisects another, then the two resulting angles are equal
In this case <ABC is bisected by BD
which means that
<ABD = <DBC
so
6x + 14 = 3x + 29
simplify and solve using inverse operations
6x + 14 = 3x + 29
-3x -14 -3x -14
3x = 15
/3 /3
x = 5
now substitute into the given values
< ABD = 6x + 14
= 5 * 6 + 14
= 30 + 14
= 44
<DBC = 3x + 29
= 5 * 3 + 29
= 15 + 29
= 44
< ABC = <ABD + <DBC
<ABC = 44 + 44
= 88

The 7th grade class experienced a 15% decrease in enrollment.Last year,the 7th grade class had 280 students. How many how many students are enrolled in the 7th grade this year?
Answers
Answer: 238
Step-by-step explanation: 10% of 280 is 28. 1% of 280 is 2.8. Multiply 2.8 times 5 and you get 14. Add 10% and 5% (28+14) and you get 15% which is 42. Subtract 42 from 280 and you get 238.
Answer:
232 students are enrolled this year.
Step-by-step explanation:
Since 15% of the enrollment of the previous year is gone, you must take 15% of the total number of students and subtract that from the total number of students.
[tex]280*0.15=42[/tex]
This tells us that the 15% decrease means there are 42 fewer students enrolled this year. Now you would just subtract 42 from 280.
280 - 42 = 232

Answers
Answer:
y = x - 8
Step-by-step explanation:
In order to solve this, we need to use point-slope form.:
y - y1 = m(x - x1)
Substitute the numbers into the equation:
y - (-8) = 1(x - 0)
y + 8 = x
y = x - 8
2x+2a=4b solve for a
Answers
Answer:
a=2b-x
Step-by-step explanation:
2x + 2a = 4b
Reorder the terms:
2a + 2x = 4b
Solving
2a + 2x = 4b
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Add '-2x' to each side of the equation.
2a + 2x + -2x = 4b + -2x
Combine like terms: 2x + -2x = 0
2a + 0 = 4b + -2x
2a = 4b + -2x
Divide each side by '2'.
a = 2b + -1x
Simplifying
a = 2b + -1x

Answers
Answer:
a = 4, b = 6 and c = 5
Step-by-step explanation:
It is given that,
[tex]\dfrac{\dfrac{1}{4}}{\dfrac{5}{6}}=\dfrac{1}{a}\times \dfrac{b}{c}[/tex]
We know that,
[tex]\dfrac{\dfrac{a}{b}}{\dfrac{c}{d}}=\dfrac{a}{b}\times \dfrac{d}{c}[/tex]
So,
[tex]\dfrac{1}{4}\times \dfrac{6}{5}=\dfrac{1}{a}\times \dfrac{b}{c}[/tex]
If we compare both sides of the equation we get,
a = 4, b = 6 and c = 5
Hence, these are the values of a,b and c.

Find the 7th term of the arithmetic sequence given a12=29 and
a16=53
a7=___
Answers
Answer:
Thus: a7=-1
Step-by-step explanation:
Arithmetic Sequences
The arithmetic sequences are identified because each term is obtained by adding or subtracting a fixed number to the previous term.
The equation to calculate the nth term of an arithmetic sequence is:
[tex]a_n=a_1+(n-1)r[/tex]
We know: a12=29, a16=53, thus
[tex]a_1+(12-1)r=29[/tex]
[tex]a_1+(16-1)r=53[/tex]
Simplifying:
[tex]a_1+11r=29[/tex]
[tex]a_1+15r=53[/tex]
Subtracting both equations:
[tex]4r=53-29=24[/tex]
Solving:
[tex]r=24/4[/tex]
r=6
The 7th term can be found as 5 terms before the 12nd:
[tex]a_7=a_{12}-5r[/tex]
[tex]a_7=29-5*6=29-30=-1[/tex]
Thus: a7=-1
