2 1/7 x 4 3/8
15/7 x 3/2
45/14 or 3 3/14
hi <3
lets call the unknown number 'x' for now and form an equation from what we know
1/3(x-9) = 15
now multiply both sides by 3
x - 9 = 45
add 9 to both sides
x = 54
hope this helps :)

Answer:
-120-x
Step-by-step explanation:
Given:
This is the same as previous one. Recall modulus property:
Keep in mind that |x+a| and |a+x| are equal via addition property.
Since the question gives interval of x < -120:
Therefore, the expression is -120-x
I guess you mean the derivative of:
√7x + √2x, if so then:
Remember that the derivative of √u = 1/(2√u) . u'
if 7x = u, then u' = 7 , hence the derivative of √7x is 7/(2√7x)
Use same logic for √2x and you will find:
y' = 7/(2√7x) + x/√2x
