Answer:
El hijo solo tardará 3 horas en arar el campo
Step-by-step explanation:
Aquí, se nos dice que ambos pasan dos horas para arar el campo mientras que el padre solo pasa 6 horas.
Queremos saber el tiempo que pasará el hijo si va a trabajar solo
Sea el área del campo x
La tasa de trabajo de ambos es x / 2
La tasa de trabajo del padre será x / 6 Deja que el tiempo que pasa el hijo sea y La tasa de trabajo del hijo es x / y
Sumando la tasa de trabajo del padre a la del hijo da la tasa de trabajo total de ambos Por lo tanto;
x / 6 + x / y = x / 2
Despegar x 1/6 + 1 /y = 1/2
1 / y = 1/2 - 1/6
1 / y= 1/3
entonces y = 3
El hijo solo tardará 3 horas en arar el campo.
Please help me find the value of x with all the work
Answer:
x = 21
Step-by-step explanation:
the angles 5x - 35 and 3x + 7 are vertical angles and congruent, thus
5x - 35 = 3x + 7 ( subtract 3x from both sides )
2x - 35 = 7 ( add 35 to both sides )
2x = 42 ( divide both sides by 2 )
x = 21
m<3=96degrees,m<5=84degrees need help with this one
Answer:
Yes because the lines never intersect.
Answer
No
Step-by-step explanation:
If a and b were parallel, then
∠ 3 and ∠ 5 would be alternate angles and congruent.
However, ∠ 3 = 96° and ∠ 5 = 84°, that is not congruent
Thus a and b are not parallel
Given three points A, B, and M, with M as the midpoint of AB, find each of the following. A(-5, -4) and M(1, -5). Find the coordinates of B.

Answer:
At a bus stop, 8 people got off the bus and 10 people go on. This means that the number of passengers increased by 2.
Step-by-step explanation:
The first one would e -8-10=-18
Second one would just be wrong. Each goldfish would be 5/4 of a dollar, so it cannot be possibly represented by the equation.
It would just be 8x=10
The last one is correct because it accurately depicts 8 people getting off(-8) and 10 people getting on(+10) which means that the passengers increased by two. This corresponds to the given equation.

3.) Light travels at a speed of 1.25 x 107 miles per minute. Pluto's average distance from the
Sun is about 3,550,000,000 miles. On average, how long does it take sunlight to reach Pluto?
I have no idea whether those numbers are correct, and I'm not gonna bother looking them up.
But you gave us a speed and a distance, and you asked for a time.
We can just go ahead and use the formula: Time = (distance) / (speed) .
IF your numbers are true, then
Time = (distance) / (speed)
Time = (3.55 x 10⁹ mi) / (1.25 x 10⁷ mi/min)
Time = (3.55 x 10⁹ / 1.25 x 10⁷) minutes
Time = 2.84 x 10² minutes
Time = 284 minutes
Time = 4 hours 44 minutes

2. Mr. Jansen needs to order picture frames for his paintings. He has $4,000 to buy 98 frames priced at $42 each. Mr. Jansen says he has enough money because 100x40=4,000. Is his reasoning corrector not? Explain your reasoning.
Answer:
The reasoning isn't correct
Step-by-step explanation:
This is becuase the given amount for each frame is 42 dollars not 40 like it is listed in the equation. Another reason the reasoning from Jansen is wrong is because he wants to buy 98 frames, not 100 like it was listed in the equation.

help meeeeeeeeeeeeeeeeeeeeeef(x) = 2x - 7. evaluate f(0.5)
Answer:
f(x)=-6
Step-by-step explanation:
f(0.5) means that x=0.5, so you substitute the x with .5 and multiply it times 2 which will get you 1. Then you subtract 7 to get -6.
Answer:
f(0.5)=-6
Step-by-step explanation:
f(x)=2x-7 f(0.5)
Just put in 0.5 for the x.
f(x)=2(0.5)-7
f(x)= 1 - 7
f(0.5) = -6
I hope you understand how to do these

The ages of three siblings combined is 27. The oldest is twice the age of the youngest. The middle child is 3 years older than the youngest.
Answer:
the oldest sibling is 12 years old.
The middle child is 9 years old.
The youngest child is 6 years old.
Step-by-step explanation:
Let the age of the youngest child be x
Then the oldest child will be 2x.
The middle child will be x + 3.
Since the combined age is 27;
x + 2x + x + 3 = 27
4x = 27 - 3
x = 24 / 4
x = 6
now 2x = 12 and x + 3 = 9
Answer:
oldest is 12
middle is 9
youngest is 6
all add up to 27
Step-by-step explanation
idk if i did this right but i did 27 -3 =24
then i divide 24 by 2 which is twelve (the oldest's age)
then 12 divided by 2 is 6 which is the age of the youngest one
6 + 3 is 9, which is the age of the middle one.

A garden table and a bench cost $600 combined.
The cost of the garden table is three times the cost of the bench.
What is the cost of the bench?
Answer:
$150
Step-by-step explanation:
A garden table and a bench together will cost $600. The actual values of the garden table and the bend are not given, but we know that the cost of a garden table will cost three times more than the bench.
Let [tex]x[/tex] = the cost of the bench.
Again, since the cost of the garden table is three times the cost of the bench ([tex]x[/tex]), we can represent the garden table as three times [tex]x[/tex] ([tex]3x[/tex]). These two terms will equal $600 when added, so let's formulate an equation:
[tex]3x+x=600[/tex]
Combine like terms:
[tex]4x=600[/tex]
Divide both sides of the equation by the coefficient of [tex]x[/tex], which is [tex]4[/tex]:
[tex]x=150[/tex]
_
Check your work by substituting [tex]150[/tex] into the original equation:
[tex]3(150)+(150)=600[/tex]
[tex]450+150=600[/tex]
[tex]600=600[/tex]
Our answer is correct!

In the figure above, lines k, l, and m intersect at a point. If x + y = u + w , which of the following must be true?
Answer:
B)
Step-by-step explanation:
First, let's write down what we know based on the Vertical Angle Theorem and the info given by the question:
1. Vertical angle theorem claims that opposite angles are the same, therefore:
y=ux=tw=z2. We know from the problem that:
x+y = u+w3. Now for the proofing:
Since x+y = u+w, let us try to cross off the variable u and see if we can get x equaling to w.
We know that y=u, so let us switch out y for another u, allowing the same variable to cross out
x+y = u+w --> x+u = u+w --> x=w
Ok now we know x=w, and recall that w=z. So x would also equal to z!
Let us try to proof z=t:
We know that x=t
But now we also know that x=z (from previous)
Therefore we can substitute the z in for x in x=t and voila z=t!
Try finding out if y=w. No matter how many equations you create, they are not the same. It would not make sense either if you use this equation: x+y = u+w. If w and x are the same then y cannot be anything except being equal to "u". We cannot prove that u is equal to anything else either.
Therefore the answer is B)
From the given equation we have x=z and t=z. Therefore, option B is the correct answer.
Given that, lines k, l, and m intersect at a point.
What is vertical angle theorem?Vertical angles theorem or vertically opposite angles theorem states that two opposite vertical angles formed when two lines intersect each other are always equal (congruent) to each other.
From the given figure,
Using vertical angle theorem, we have
x°=t°
y°=u°
w°=z°
If x + y = u + w, then
x+u=u+z
⇒ x=z
If x + y = u + w, then
t+u=u + z
⇒ t=z
So, x=z and t=z
From the given equation we have x=z and t=z. Therefore, option B is the correct answer.

Tell whether the relationship is proportional?
Solve for the value of z. (z+2)° (4z-7)°
Answer:
Z=0.8
Step-by-step explanation:
Step-by-step explanation:
Combine the opposite terms
2z+2+4z=7
Add
2z and 4z
6z+2=7
Move all terms not containing z to the right side of the equation.
Subtract 2 from both sides of the equation.
6z=7−2
6z=5
Divide each term:
6z/6 = 5/6
Decimal Form:
z=0.8
