Answer:

a, t = (p - 4)/5

b. t =√(a + 4)

c. t = d/(5-f)

Step-by-step explanation:

a. p = 5t + 4

To make t the subject of the equation, subtract 4 from both sides

p - 4 = 5t + 4 - 4

p - 4 = 5t

Divide both sides by 5

(p - 4)/5 = t

t = (p - 4)/5

b. a = t2 - 4

to make t the subject, add 4 to both sides

a + 4 = t2 - 4 + 4

a + 4 = t2

find the root of both sides

t =√(a + 4)

c. d = t(5 – f)

to make t the subject, divide both sides by 5 - f

d/(5-f) = t(5 – f)/(5 – f)

t = d/(5-f)

Compare the rates to find which is greater. 50 envelopes for $2.49 or 90 envelopes for $5.50

Dmitry_Shevchenko [17]

We describe this as cost per envelope which tells you the cost gets divided by the number of envelopes.

$2.49/50 = 0.0498 cents per envelope

$5.50/90 = 0.0611 cents per envelope.

So the 90 for $5.50 costs more per envelope than the 50 for $2.49

Find the limit as x approaches 0 of x/sin3x

frozen [14]

$\lim_{x \to 0} \frac{x}{sin 3x} = \\ =\frac{0}{0}= \\ = \lim_{x \to 0} \frac{3x}{3sin3x} =$
= 1/3 ( because the limit as x approaches 0 of t/sin t = 1 ).
