Work: x+4/x=45
×x both sides
X+4= 45X
-X both sides
4=45x-x
4=44x
÷44 both sides
X=1/11
Answer: x=1/11
Check your work:
1/11+4/1/11=45
1/11+44/11/(1/11)=45
45/11÷1/11=45
45/11×11/1=45
45=45

Answer is correct

Let's solve your equation step-by-step.
x+4/x = 45

Step 1: Multiply both sides by x.
x + 4 - 45x = 45x - 45x (subtract 45x from both sides)
-44x + 4 = 0
-44x + 4 - 4 = 0 - 4 (subtract from both sides)
-44x = -4
-44x/-44 = -4/-44 (divide both sides by -44)
x = 1/11

Check the answer and make sure it works x = 1/11 (works in original equation).
Final Answer x = 1/11

NOTE!!!

Forward Slash is meant as a fraction divider in this instance

The concentration of a drug in the bloodstream C(t) at any time t, in hours, is described by the equationC(t)=100t/t^2+25where t

alisha [4.7K]

Answer:

It will take 5 hours until it reaches its maximum concentration.

Step-by-step explanation:

The maximum concentration will happen in t hours. t is found when

$C'(t) = 0$

In this problem

$C(t) = \frac{100t}{t^{2} + 25}$

Applying the quotient derivative formula

$C'(t) = \frac{(100t)'(t^{2} + 25) - (t^{2} + 25)'(100t)}{(t^{2} + 25)^{2}}$

$C'(t) = \frac{100t^{2} + 2500 - 200t^{2}}{(t^{2} + 25)^{2}}$

$C'(t) = \frac{-100t^{2} + 2500}{(t^{2} + 25)^{2}}$

A fraction is equal to zero when the numerator is 0. So

$-100t^{2} + 2500 = 0$

$100t^{2} = 2500$

$t^{2} = 25$

$t = \pm \sqrt{25}$

$t = \pm 5$

We use only positive value.

It will take 5 hours until it reaches its maximum concentration.

Determine the GCF of 3x^3,6x^2 and 15x

UNO [17]

Answer:

3x

Step-by-step explanation:

The GCF would be 3x, if you took out 3x from those numbers you'd be left with x^2, 2x, and 5, which can't be reduced any further.

-(3x - 12) = 9x - 4 *Hint: Distributive the negative

Deffense [45]

Answer: x=1+1/3

Step-by-step explanation: -(3x-12)=9x-4

We move all terms to the left:

-(3x-12)-(9x-4)=0

We get rid of parentheses

-3x-9x+12+4=0

We add all the numbers together, and all the variables

-12x+16=0

We move all terms containing x to the left, all other terms to the right

-12x=-16

x=-16/-12

x=1+1/3
