Answer:
x < 3
Step-by-step explanation:
Step 1: Write inequality
4x + 8 > 2(3x + 1)
Step 2: Solve for x
Distribute 2: 4x + 8 > 6x + 2Subtract 4x on both sides: 8 > 2x + 2Subtract 2 on both sides: 6 > 2xDivide both sides by 2: 3 > xRewrite: x < 3Here we see that any value smaller than 3 will be a solution.

Julio es un joven muy emprendedor y ha iniciado un negocio de venta de audífonos y cargadores. Este mes, separa la cantidad de dinero, que ha obtenido en sus ventas, en dos partes: gastos y ganancias y se percata que están a razón de 5 es a 3. Del dinero que gasta, ⅗ lo gasta en compra de más mercadería, 10% en servicios de agua, luz e internet, el restante, S/ 150,60 lo gasta en su alimentación. ¿Cuánto ha sido su ganancia en este mes?
Answer:
Julio ha ganado 90,36 soles en este mes.
Step-by-step explanation:
Tras una lectura cuidadosa del enunciado podemos inferir que por cada 5 soles destinados al gasto hay 3 soles destinados a ganancias. En lo respectivo a los gastos, la razon del componente restante, cuyo valor es de 150,60 soles, es:
[tex]r = 1 - \frac{3}{5}-\frac{1}{10}[/tex]
[tex]r = 1 - \frac{6}{10}-\frac{1}{10}[/tex]
[tex]r = \frac{3}{10}[/tex]
En otras palabras, el componente restante corresponde al 30 % del dinero destinado a gastos. Entonces, el dinero total destinado a gastos es:
[tex]x = \frac{150,60\,soles}{0.3}[/tex]
[tex]x = 502\,soles[/tex]
Sabiendo la razón existente, es decir, 5 soles para gastos por 3 soles para ganancias, obtenemos la ganancia obtenida por Julio en este mes por la siguiente regla de tres simple:
[tex]y = 150,60\,soles \times \frac{3\,soles}{5\,soles}[/tex]
[tex]y = 90,36\,soles[/tex]
Julio ha ganado 90,36 soles en este mes.

David has two jobs. He earns $8 per hour babysitting his neighbor's children and he earns $11 per hour working at the coffee shop. If David worked 15 hours at the coffee shop, write an inequality to represent the number of hours, x, babysitting that David will need to work to earn a minimum of $200. Use the inequality to find the number of full hours he must babysit to reach his goal of $200.
Answer:
The number of full hours he must babysit to reach his goal of $200 is 5 hours
Step-by-step explanation:
Let x be the no. of hours he must babysit to reach his goal of $200.
Cost for working 1 hour at coffee shop = $11
Cost for working 15 hour at coffee shop = [tex]11 \times 15=165[/tex]
Cost for working 1 hour babysitting = $8
Cost for working x hour babysitting = 8x
We are supposed to find the number of full hours he must babysit to reach his goal of $200.
165+8x=200
8x=200-165
[tex]x=\frac{200-165}{8}[/tex]
x=4.375
Hence The number of full hours he must babysit to reach his goal of $200 is 5 hours

Answer:
Step-by-step explanation:
Am equation with infinite number of solution means that the equation has uncountable solutions.
Let's analyse each options
For the expression 3x-1 = 3x+1
Collect like terms
3x-3x = 1+1
0x = 2
Divide both sides by 0
x = 2/0
x = infinity
This shows that the expression 3x-1 = 3x+1 has infinite number of solution
Also considering the third expression
3(x-1) = 3x+3
Open the parenthesis
3x-3 = 3x+3
Collect like terms
3x-3x = 3+3
0x = 6
x = 6/0.
x = infinity
Thus also shows that expression 3(x-1) = 3x+3 has infinite number of solution.
3x-1 = 3x+1
3(x-1) = 3x+3
Answerr for money!!!
Answer:
Line s and Line t are parallel.
Step-by-step explanation:
Now, we know that angles 1 and 2 are congruent, because they have the same angle measures. Now, looking at their positions, we can see that they are alternate exterior angles.
By the converse of the Alternate Exterior Angle, (I do not remember exactly how the theorem went) if two lines are cut by a transversal and have congruent alternate exterior angles, then the lines are parallel. Using this theorem, we can find that lines s and t are parallel, because they are cut by a transversal and their alternate exterior angles are congruent.
I hope you find my answer and explanation to be helpful. Happy studying.

An object was moving at a rate of 18.2 feet per second for 38.5 seconds. How far did the object travel?
Answer:
700.7
Step-by-step explanation:
You're looking for distance. So all you have to do is 18.2 x 28.5 and you'll get your answer.
Hope this helps. :)
The distance travelled 700.7 feet
What is speed- distance formula?Speed = Distance/Time – This tells us how slow or fast an object moves. It describes the distance travelled divided by the time taken to cover the distance. Speed is directly Proportional to Distance and Inversely proportional to Time. Hence,Distance = Speed X Time, and Time = Distance / Speed, as the speed increases the time taken will decrease and vice versa.given:
speed= 18.2 ft/ sec
time= 38.5 sec
So,
speed= Distance/ time
distance= speed * time
= 18.2 * 38.5
= 700.7 feet

It has been estimated that only about 30% of California residents have adequate earthquake supplies. Suppose we are interested in the number of California residents we must survey until we find a resident who does not have adequate earthquake supplies. a. In words, define the random variable X. b.

HowmanyCaliforniaresidentsdoyouexpecttoneedtosurveyuntilyoufindaCaliforniaresidentwhodoesnot have adequate earthquake supplies? g. How many California residents do you expect to need to survey until you find a California resident who does have adequate earthquake supplies?
Answer:
Step-by-step explanation:
We are given that 30% of California residents have adequate earthquake supplies.
a) Ramon variable X denotes the number of the california residents that have adequate earthquake insurance
B) x can take value 1 ,2 ,3 ......
C)The distribution of random variable is geometric distribution with parameter p=0.3
The pmf of geometric distribution is
[tex]P(X=x)=0.3(1-0.3)^{x-1} , x=1,2,3...[/tex]
D)P(X=1) or P(X=2)=P(X=1)+P(X=2)
P(X=1) or P(X=2)=[tex]0.3(1-0.3)^{1-1}+0.3(1-0.3)^{2-1}=0.51[/tex]
E)
[tex]P(X \geq 3)=1-P(X<3)\\P(X \geq 3)=1-(P(X=1)+P(X=2))\\P(X \geq 3)=1-0.51\\P(X \geq 3)=0.49[/tex]
F)
[tex]E(X)=\frac{1}{p}[/tex]
p is the resident who does not have adequate earthquake supplies.
p = 1-0.3 = 0.7
[tex]E(X)=\frac{1}{0.7}=1.42[/tex]
G)[tex]E(X)=\frac{1}{q}=\frac{1}{0.3}=3.33[/tex]
