The question is incomplete but a possibility is that the given parameters are points on a straight line.
I'll answer base on that assumption.
[tex]RS = 6y + 2[/tex]
[tex]ST =2y + 7[/tex]
[tex]RT =13y -21[/tex]
To solve for y, we have that:
[tex]RT = RS + ST[/tex]
This gives:
[tex]13y - 21 = 6y + 2 + 2y + 7[/tex]
Collect Like Terms
[tex]13y - 6y - 2y = 21 +2+7[/tex]
[tex]5y = 30[/tex]
Divide both sides by 5
[tex]y = 6[/tex]
To get the measure of each line. Substitute 6 for y in
[tex]RS = 6y + 2[/tex]
[tex]ST =2y + 7[/tex]
[tex]RT =13y -21[/tex]
[tex]RS = 6 * 6 + 2 = 36 + 2 = 38[/tex]
[tex]ST = 2*6 + 7 = 12 +7 = 19[/tex]
[tex]RT = 13*6 - 21 = 78 - 21 = 57[/tex]

Given that line CD is a perpendicular bisector of triangle ABC, if side AB has a length of 6 and side AC has a length of 12 what is the length of side CD? Write your answer to the
nearest hundredth ie 179.50.
Using the Pythagorean Theorem, we can determine that the length of CD is 11.62, rounded to the closest hundredth.
How Should One Put the Pythagorean Theorem Into Practice?When the length of the longest side of a right triangle is squared, the result will be equal to the total of the squares of the lengths of the other two sides of the right triangle that are smaller.
Taking into account the following:
Side AB = 6
Side AC = 12
The perpendicular bisector theory states that AD equals half of AB, which equals half of (6), which equals three.
By using the Pythagorean theorem, we get the following:
The length of the CD is equal to (AC2 - AD2)
The length of the CD is equal to 122 minus 32.
The length of the CD equals (144 - 9)
11.62 is the length of the CD.
Consequently, by using the Pythagorean Theorem, we can determine that the length of the CD is 11.62, rounded to the closest hundredth.

Tina is saving to buy a notebook computer. She has two options. The first option is to put $400 away initially and save $10 every month. The second option is to put $300 away initially and save $30 every month. After how many months would Tina save the same amount using either option? How much would she save with either option?
Answer:
After 5 months, both options will have saved 450$
Step-by-step explanation:
The first option can be modeled with the expression
400 + 10x
The second option can be modeled with the expression
300 + 30x
The variable x represents the months so in order to find the month where Tina saves the same amount, we set the expressions equal to each other.
400 + 10x = 300 + 30x
solve for x
20x = 100
x = 5
After 5 months, Tina will save the same amount of money which is
400 + 10*5 = $450

Answer:
( [tex]\frac{22}{7}[/tex] , [tex]\frac{44}{7}[/tex] )
Step-by-step explanation:
3x + 2y = 22 ....... (1)
- x+ 4y = 22 ........ (2)
3 × (2) + (1)
(3x - 3x) + (2y + 12y) = 22 + 66 ( variable "x" is eliminated )
14y = 88
y = [tex]\frac{44}{7}[/tex]
- x + 4( [tex]\frac{44}{7}[/tex] ) = 22
x = [tex]\frac{176}{7}[/tex] - [tex]\frac{154}{7}[/tex] = [tex]\frac{22}{7}[/tex]

-. A 6-foot-tall man is standing 50 feet from a flagpole. When he looks at the top of the flagpole,
the angle of elevation is 39º. Find the height of the flagpole to the nearest foot.
Answer:
The height of the flagpole is 46 feet
Step-by-step explanation:
First we find the ratio to connect the variables
Tan(∅) = opposite/adjacent
Plug in the Variables
Tan(39) = x/50
Solve for x
50*tan(39) = x
x = 40.48
Don't forget to include the man's height
40.48 + 6 = 46.48
Drag all of the steps necessary into the box to find the product of 2 . 7 × 6 . 4 using partial products.
The product of the numbers 2.7 x 6.4 using partial products is 17.28
How to calculate the value?In order to get the product of the values using partial products, we will use the concept of repeated addition as shown:
2.7 x 6.4
For 2.7 = 2.0 + 0.7
6.4 = 6.0 + 0.4
Substituting the sum into the product, we will have:
2.7 x 6.4 = (2.0 + 0.7) x (6.0 +0.4)
2.7 x 6.4 = 2.0(6.0) + 2(0.4) + 0.7(6) + 0.7(0.4)
2.7 x 6.4 = 12 + 0.8 + 4.2 + 0.28
2.7 x 6.4 = 17.28
Therefore, the value is 17.28.

At a local high school, 40% of the students drink soda regularly, 30% of the students drink coffee regularly, and 10% of the students drink both regularly. If a
student is randomly selected from this school, what is the probability that the student drinks soda or coffee regularly?
A. 70%
B. 20%
C. 80%
D. 60%
Answer:
c he is your answer dear friend♀️♀️
Probability that the student drinks soda or coffee regularly is 60%
Option D is correct
Percentage of students that drink soda regularly, P(s) = 40%
Percentage of the students that drink coffee regularly, P(c) = 30%
Percentage of students that drink both coffee and soda regularly,
P(s and c) = 10%
Percentage of students that drink coffee or soda regularly is:
P(s or c) = P(s) + P(c) - P(s and c)
P(s or c) = 40 + 30 - 10
P(s or c) = 70 - 10
P(s or c) = 60
Probability that the student drinks soda or coffee regularly is 60%

Answer:
m<S = 80°
Step-by-step explanation:
The figure given shows a cyclic quadrilateral.
Angle S and Angle Q are opposite angles of the cyclic quadrilateral. Thus, it is known that opposite angles of a cyclic quadrilateral are supplementary. Since m<Q = 100°
Therefore:
m<S = 180° - 100°
m<S = 80°
