Answer: x=4

Step-by-step explanation:

You need to find the value of the variable "x".

To solve for "x", the first step is to apply the Subtraction property of equality, which states that:

If\ a=b\ then\ a-c=b-c

Then, you need to subtract 4 from both sides of the equation:

3x + 4 = 16\\3x + 4-4 = 16-4\\3x=12

And finally, you can apply the Division property of equality, which states that:

If\ a=b\ then\ \frac{a}{c}=\frac{b}{c}

Then you can divide both sides of the equation by 3, getting:

\frac{3x}{3}=\frac{12}{3}\\\\x=4

Solve for t if p≠q<br> (t+p)/q - q/p = (t-q)/p + p/q
german

Answer:

.. q T 0 = (q/p)a (q/p)a − (q/p)T−10 if p ≠ q and qT0 = 1 − T0/a if p = q = 1/2.

Step-by-step explanation:

Suppose that there are two different solutions, p and q, in [a, b]. Thus p =g(p) q =g(q) p ≠ q The function g(x) satisfies the hypotheses of the mean-value ... that g(p) –g(q) = (p – q) g׳(t) Because g(p) =p and g(q) = q, the left side of Eq. (1-3) may...

DerKrebs [107]

Answer:

$8.75

Step-by-step explanation:

STEP TO TAKE TO DETERMINE THE ANSWER

Multiply 13/4 pounds by the cost of one pound of peanut. To do this, convert 13/4 to an improper fraction and then multiply it by $5

1\frac{3}{4} = \frac{7}{4}

\frac{7}{4} × 5 = \frac{35}{4} = 8\frac{3}{4} = $8.75

World population is approximately upper p equals 6.4 left-parenthesis 1.0126 right-parenthesis superscript t, with upper p in bi
Leviafan [203]

Given equation is

P=6.4(1.0126)^t

It gives approx world population in billions for t years since 2004.


Answer(a):

Compare with growth formula P=a(b)^t, we get:

growth factor b = 1.0126

We know that if r is the percent rate of growth then

1+r=b

1+r=1.0126

r=0.0126

Hence the yearly percent rate of growth of the world population is 0.0126 or 1.26%.


Answer(b):

To find worlds population in 2004, plug t=0 because year is counted from 2004.

P=6.4(1.0126)^0 = 6.4*1 = 6.40

Hence answer is 6.40 billion.


To find worlds population in 2018, plug t=2018-2004=14 because year is counted from 2004.

P=6.4(1.0126)^{14} = 6.4*1.19160117479 = 7.62624751867

Hence answer is approx 7.63 billion.


Answer(c):

Average rate of change of the world population between 2004 and 2018 is given by:

\frac{P\left(Year_{2018}\right)-P\left(year_{2004}\right)}{2018-2004}

=\frac{P\left(14\right)-P\left(0\right)}{14-0}

=\frac{7.63-6.40}{14}

=0.0878571428571

Hence answer is approx 0.0878571428571 billion per year.

To convert it into millions, multiply by 1000

So we get 0.0878571428571*1000 = 87.8571428571

Which is approx 88 to the nearest integer

Hence final answer is approx 88 millions per year.
