Arun is twice as old as Shreet 5 years ago his age was three times shree age find their present ages​
Mariulka [41]

Answer:  Arun is now 20, Shree is 10 years old

Step-by-step explanation:  

In the system of equations Arun's age is a. Shree is s

a = 2s .(current age equation)  Subtract 5 from each for five years ago,

a-5 = 3(s-5) . Substitute 2s for a in the second equation

2s -5 = 3(s-5)  distribute and reorganize

2s-5 = 3s -15 .   15 - 5 = 3s - 2s

10 = s .  Substitute into the first equation to find a

a = 2(10)

a = 20

5 years ago  Shree was 5 and Arun was 15

For what numbers x, -2π ≤ x ≤ 2π, does the graph of y = csc(x) have vertical asymptotes?
yulyashka [42]
Well tan x has asymptotes every 90 degrees, or in radian mode, every pi divided by two. since cot is the inverse and the aymsptotes land on every 180 degrees, meaning the equation can be x ≠ \pi n, nEI

If R is the midpoint of TS, TR = 5x - 12, and RS = 3x + 8, find TS.
GenaCL600 [577]

Answer:

5x -12 = 3x +8 (set the two = each other because they are the same length)

2x- 12= 8 (subtract 3x from both sides)

2x = 20 (add 12 to both sides)

x=10 (what x= for both expressions)

5(10) -12 (plug it into the first one to see what the length is and to see they're =

50 - 12 ( I already multiplied, now subtract)

38 (what the length of TR is)

3(10) +8 (plug it in again but into the other expression)

30+8 (multiply and add)

38 (the two have the same answer, so the x-value is correct.)

38+38= 76 (add the lengths of RS and TR and you get the length of TS)

Step-by-step explanation:

I hope this helps :)
