5p+2r=q
Move variable to the right
5p=q -2r
Divide both sides of the
equation by 5
q - 2
p =— — r
5 - 5
The final solution for
p is
q - 2
p =— — r, rER, qER
5 - 5
I cannot make the E like it should be made in mathematics on this keyboard. An elongated E.

Really ! What are you going to do when the moment comes
on an exam when you have to do it on your own ?
<u>(1/4) (8x + 16) = -10</u>
Multiply each side by 4 :
8x + 16 = -40
Subtract 16 from each side:
8x = -56
Divide each side by 8 :
<u>x = -7</u>
42+7a= 7(6+a)
By noticing they both have a factor of 7, I was able to find the equation.
Answer:
Step-by-step explanation:
By geometric mean theorem,
In a triangle ABC,
y² = 60
y = √60
y = 7.75
Similarly, 
x² = 40
x = √40
x = 6.32
