What is this pls help me 4/x+11=35/3

Mathematics
1 answer:
olga55 [171]2 years ago
5 0

Answer:

x=-\frac{373}{35}

Step-by-step explanation:

4/x+11=35/3

Cross Multiply

12=\left(x+11\right)\cdot \:35

Switch Sides

\left(x+11\right)\cdot \:35=12

Divide both sides by 35

\frac{\left(x+11\right)\cdot \:35}{35}

Simplify

x+11=\frac{12}{35}

Subtract 11 from both sides

x+11-11=\frac{12}{35}-11

Simplify

x=-\frac{373}{35}

And that is your answer.

Find an equation of the line with the slope m=6 that passes through the point (4,4). Write the equation in the form Ax + By = C
Ainat [17]

Answer:

Y - 6x = - 20

Step-by-step explanation:

Y = 6x + c

Substituting the value of x and y

4 = 24 + c

Subtracting 24 from both sides

C = - 20

Y = 6x - 20

Subtracting 6x from both sides

Y - 6x =- 20

Brielle and Joshua are running a half marathon race, which is 13.1 miles long. It takes Brielle 10 minutes to run 1.25 miles and
CaHeK987 [17]

Answer: Brielle will run the marathon faster.

Brielle = 104.8 minutes  

Joshua = 157.2 minutes

Step-by-step explanation:

Speed rate = distance /time

Brielle = 1.25 /10 = 0.125 miles per minute

Joshua = 1.5/18 = 0.083333 =1/12 miles per minute

Since 0.125 (Brielle) > 1/12 (Joshua)

Brielle will run the marathon faster.

To calculate the time that takes each one to run the entire race (13.1 miles)

Time= distance / speed

  • Brielle = 13.1 /0.125 = 104.8 minutes
  • Joshua = 13.1 / (1/12)= 157.2 minutes

Feel free to ask for more if needed or if you did not understand something.

The veloctiy of sound in air is given by the equation v=20 times the square root of 273+t where v is the velocity in meters per
Nikitich [7]
So we just need to plug in our values and solve
v = 20 \sqrt{273 + t}
we are given v is 369 so we have
369 = 20 \sqrt{273 + x}
now we solve for x.
divide both sides by 20
square both sides
subtract 273 from both sides
369 = 20 \sqrt{273 + x}  \\ 18.45 =  \sqrt{273 + x}  \\ 340.40 = 273 + x \\ x = 67.4
so a temp of about 67 degrees C
