Answer:
Step-by-step explanation:
Let the number be x,
4x+5 = 3(x-2)
4x+5 = 3x-6
Collect like terms
4x-3x = -5-6
x. = -11

<span> ∫ [ln(√t) / t] dx
let √t = u
t= u² → dx = 2u du
substitute in the integral
∫ [ln(√t) / t] dx = ∫ (ln u / u²) 2u du = ∫ (ln u / u²) 2u du = 2 ∫ (ln u / u) du
let ln u = x → d (ln u) = dx→ (1/u)du = dx
substituting again
2 ∫ (ln u / u) du = 2 ∫ x dx= 2 x²/ 2 = x² + c which,
substituting ln² u + c
as of the first
substitution ln²(√t) + c
it concludes that
∫ [ln(√t) / t] dx = ln²(√t) + c
hope it helps

There should be 480 visitors (including children)
This would be because 60% of the people have 180 children so divide by 6 and you have 30 or 10%, multiply the 30 by 10 (to get a hundred percent [300] ) and add the children to get 480.
Answer:
f(x) = 10n
Step-by-step explanation:
If met with questions like these, the term "for each" means to multiply. simply write an equation that multiplies n and 10. Also "f(x)" can be substituted for "y" if that is what your instructor taught you.
Answer:
1/4 miles per minute
or
15 miles per hour
Step-by-step explanation:
Rember the equation
time * speed = distance
or
T * S = D
now plug in the known values
time = 20 min
or you could also say that the time is 1/3 hour
distance = 5 miles
20min * S = 5miles
divide by 20
S = 5 / 20
S = 1/4 mile per minute
another way of doing this with different units is
1/3 hour * S = 5 miles
divide 1/3 (same as multiplying 3)
s = 15 miles per hour
