Answer:

x = 63

Step-by-step explanation:

we know that...

(x will be the stand-in for "your number")

x ÷ 7 + 25 = 34

(x ÷ 7) + 25 = 34

To find x, we have to isolate x

first, we can subtract 25 from both sides (remember, if you do an action on one side, you must do the same action on the other side)

{why are we subtracting? we need to do the opposite of a sign to get rid of it. By subtracting, we are <em>undoing</em> addition; by multiplying we are undoing division (and vice versa)  }

(x ÷ 7) + 25 = 34

          - 25    - 25     (subtract 25)

x ÷ 7 = 9

  × 7    ×7       (multiplying by 7 to get rid of the "÷7")

x = 63

now, we can test out our x-value:

(63 ÷ 7)  +25 = 34

( 9 ) + 25 = 34

34 = 34

because this equation is true, we can be certain that x = 63

hope this helps!

A large tank is partially filled with 100 gallons of fluid in which 20 pounds of salt is dissolved. Brine containing 1 2 pound o
sertanlavr [38]

Answer:

Step-by-step explanation:

From the given information:

R_{in} = ( \dfrac{1}{2} \ lb/gal) (6)\ gal /min \\ \\R_{in} = 3 \ lb/min

Given that the solution is pumped at a slower rate of 4gal/min

Then:

R_{out} = \dfrac{4A}{100+(6-4)t}

R_{out}= \dfrac{2A}{50+t}

The differential equation can be expressed as:

\dfrac{dA}{dt}+ \dfrac{2}{50+t}A = 3  \ \ \ ... (1)

Integrating the linear differential equation; we have::

\int_c \dfrac{2}{50 +t}dt = e^{2In |50+t|

\int_c \dfrac{2}{50 +t}dt = (50+t)^2

multiplying above integrating factor fields; we have:

(50 +t)^2 \dfrac{dA}{dt} + 2 (50 + t)A = 3 (50 +t)^2

\dfrac{d}{dt}\bigg [ (50 +t)^2 A \bigg ] = 3 (50 +t)^2

(50 + t)^2 A = (50 + t)^3+c

A = (50 + t) + c(50 + t)²

Using the given conditions:

A(0) = 20

⇒ 20 = 50 + c (50)⁻²

-30 = c(50) ⁻²

c = -30 × 2500

c =  -75000

A = (50+t) - 75000(50 + t)⁻²

The no. of pounds of salt in the tank after 35 minutes is:

A(35) = (50 + 35) - 75000(50 + 35)⁻²

A(35) = 85 - \dfrac{75000}{7225}

A(35) =69.6193 pounds

A(35) \simeq 70 pounds

Thus; the number of pounds of salt in the tank after 35 minutes is 70 pounds.
