What is the value of x?

1 answer:

3 0

Answer:
x = 11/36

Explanation:
Step 1 - Write down the equation

x + 4/9 = 3/4

Step 2 - Subtract 4/9 from both sides of the equation

x + 4/9 = 3/4
x + 4/9 - 4/9 = 3/4 - 4/9
x = 11/36

Extra:
If you would like to check and make sure the value of x is correct, simply replace x with its value and solve.

x + 4/9 = 3/4
11/36 + 4/9 = 3/4
27/36 = 3/4
3/4 = 3/4 ✅

So, the value of x is in fact 11/36

Answer:

52/145 ≈ 0.359 = 35.9%

Step-by-step explanation:

There are a total of 76+69 = 145 people in the room. Of them, 29+23 = 52 earn more than $50,000 per year. The probability of choosing one of those at random is 52/145 ≈ 0.35862 ≈ 35.9%.

___

For all of these probability problems, the probability of selecting an item with particular characteristics is the ratio of the number of such items to the total number of possible choices.

Suppose that a large mixing tank initially holds 700 gallons of water in which 50 pounds of salt have been dissolved. another br

labwork [276]

$\dfrac{\mathrm dA}{\mathrm dt}=\dfrac{3\text{ gal}}{1\text{ min}}\dfrac{4\text{ lb}}{1\text{ gal}}-\dfrac{2\text{ gal}}{1\text{ min}}\dfrac{A\text{ lb}}{700+(3-2)t\text{ gal}}$
$\iff A'+\dfrac2{700+t}A=12$

$(700+t)^2A'+2(700+t)A=12(700+t)^2$
$((700+t)^2A)'=12(700+t)^2$
$(700+t)^2A=4(700+t)^3+C$
$A=4(700+t)+\dfrac C{(700+t)^2}$

Initially, the tank contains 50 lbs of salt in 700 gal of solution, i.e. $A(0)=\dfrac{50}{700}=\dfrac5{70}$ , so

$\dfrac5{70}=2800+\dfrac C{700^2}$

Use this to solve for $C$ .
