Sally is 45 and Beth is 15.

45 + 15 = 60

15*3 = 45

Answer: Present age of Beth is 24 years.

And Present age of Sally becomes 36 years.

Step-by-step explanation:

Let the present age of Beth be 'x'.

Six years ago,

Age of Beth becomes (x-6) years

Age of Sally becomes

3(x-6)\ yrs

Sum of Sally and Beth's age = 60

According to question, it becomes

x-6+3(x-6)=60+6+6\\\\x-6+3x-18=72\\\\4x-24=72\\\\4x=72+24\\\\4x=96\\\\x=\frac{96}{4}=24\ yrs

So, Present age of Beth is 24 years.

And Present age of Sally becomes 60-24=36 years.

What is the slope-intercept form of the equation of a line that passes through (5, -4) and has a slope of 34?
Alla [95]
One way to find the slope-intercept form is to plug the given values into point-slope form, y - y_{1} = m (x - x_{1}), where x_{1} and y_{1} are the coordinate points and m is the slope. Then, you solve for y.

y - y_{1} = m (x - x_{1})   Plug in the values
  y - (-4) = 34 (x - 5)         Fix the minus negative four
     y + 4 = 34 (x - 5)         Use the Distributive Property
     y + 4 = 34x - 170        Subtract 4 from both sides
           y = 34x - 174

The slope-intercept form of the equation that passes through (5, -4) and has a slope of 34 is y = 34x - 174.

Q=p(r+s) solve for p
pav-90 [236]
Q = p(r+s)
--------------
(r+s) (r+s) Divide both sides by (r+s) so you can get the p bu itself this way you get q / (r+s) = p
