Answer:7
Step-by-step explanation:10+9.50= 19.50
$30-$19.50=$10.50
$10.50/$1.50= 7
Hello im really thinking its yes
so yes
hope its correct!!!

Answer:
a
No singular point due to the exponent in the solution
The interval is 
b
NONE
Step-by-step explanation:
From the question we are told that
The generally solution is mathematically represented as
=> 
integrating both sides
=> 
=> 
=> 
Here 
=> 
From the above equation we see that the domain for x has no singular point the interval is
Also there is no transient term in the general solution obtained because as 
there no case where 
Answer:
Step-by-step explanation:
(a) You use the fact that the lengths RS and ST total the length RT.
RS +ST = RT
(6y+3) +(3y+5) = 80 . . . . . substitute the given values
9y +8 = 80 . . . . . . . . . . . . .simplify
9y = 72 . . . . . . . . . . . . . . . .subtract 8
72/9 = y = 8 . . . . . . . . . . . .divide by the coefficient of y
___
(b) Now, the value of y can be substituted into the expressions for RS and ST to find their lengths.
RS = 6y +3 = 6·8 +3
RS = 51
ST = 3y +5 = 3·8 +5
ST = 29
___
<em>Check</em>
RS +ST = 51 +29 = 80 = RT . . . . the numbers check OK
3x+20=100
Now you would need to move the constant to the right side and change within it’s sign
3x=100-20
Now you would subtract the numbers so for 100-20 would give you 80
So now you then do 3x=80
But if you want to divide the equation, divide it by both sides by 3
Which would give you x=80/3, x=26.6 or x=26 2/3
