Answer:
[tex]x=3.5[/tex]
Step-by-step explanation:
Notice that CD bisects Angle C.
Then by the Angle Bisector Theorem, we can write the following proportion:
[tex]\frac{6}{4.2}=\frac{5}{x}[/tex]
Now, we can solve for x. Cross multiply:
[tex]5(4.2)=6(x)[/tex]
Multiply:
[tex]21=6x[/tex]
Divide both sides by 6:
[tex]x=21/6=7/2=3.5[/tex]
Hence, the vale of x is 3.5.

A baker sells bread for $4 a loaf and rolls for $1 each. The baker needs to sell $36 worth of baked goods by
the end of the day.
Enter a linear equation that describes the problem.
An equation for the value of the baked goods is
bread sold, and r is the number of rolls sold.
= $36, where b is the number of loaves of
Answers
Explanation:
Cost of 1 loaf of bread = $4
Cost of 1 roll = $1
The baker needs to sell both items and it should be worth $36.
To find the linear equation, Suppose, the baker sells "b" loaves of bread and "r" rolls.
Then the total cost of the sales has to be $36.
So, the linear equation will be:

The values of x that are solutions to the given inequality are 0, 3, and 6.
What is inequality?It shows a relationship between two numbers or two expressions.
There are commonly used four inequalities:
Less than = <
Greater than = >
Less than and equal = ≤
Greater than and equal = ≥
We have,
7 + 4x > x - 2
Solve for x.
7 + 4x > x - 2
Subtract x on both sides.
7 + 4x - x > -2
7 + 3x > -2
Subtract 7 on both sides.
7 + 3x - 7 > -2 - 7
3x > -9
Divide both sides by 3.
x > -3
This means x is greater than -3.
i.e -2, -1, 0 , 1, 2, 3, 4, 5, . . . . .
From the given option we can select the correct answers.
We see that,
0, 3, and 6 are the correct answer.

A sequence has an initial value (I) of -17 and its fourth term (a4) is 35. What is its general equation? Its 14th term?
Also, A sequence has a CR of 4/5 and its eighth term (a8) is (393216/3125). What is its general equation? Its 3rd term?
Answers
Answer:
The sequence is an Arthemtic ProgressionAn=A1+(n-1)d
A1 is first term, An is nth term, n is number of term, and d is common difference
therefore
A4=35, A1= -17
A4=A1+(4-1)d
35= -17+3d
35+17=3d
52=3d
52/3=3d/3
14=d
common diffrence(d)=14
The general solution is given byAn= -17+(n-1)14
An= -17+14n-14
An= -31+14n
An= 14n-31
A14 term, means n=14
From An=A1+(n-1)d
A14= -17+(14-1)14
= -17+(13×14)
= -17+182
= 165.
Therfore, the 14th term is 165.
2. A sequence has a CR of 4/5 and its eighth term (a8) is (393216/3125). What is its general equation? Its 3rd term?
solution
common ratio(r)=4/5
eighth term(G8)=393216/3125
From Gn= G1r^(n-1)
G8 means n=8
G8=G1r^(n-1)
393216/3125=G1(4/5)^(8-1)
393216/3125=G1(4/5)^7
G1=(393216/3125)/(4/5)^7
G1=600
The first term is given by G1=600
ThereforeThe General equation is given by
The General equation is given by Gn= 600(4/5)^(n-1)
3rd term (G3)
G3= G1(4/5)^(3-1) where n=3,
=600(4/5)^2
=600(16/25)
=384
Therefore, the 3rd term is given by G3= 384.
