Solve the equation: (3)/(7)-(2)/(5)x=5

Answers

Answer 1

Answer:

x = - [tex]\frac{80}{7}[/tex]

Step-by-step explanation:

Given

[tex]\frac{3}{7}[/tex] - [tex]\frac{2}{5}[/tex] x = 5

Multiply through by 35 ( the lcm of 7 and 5 ) to clear the fractions

15 - 14x = 175 ( subtract 15 from both sides )

- 14x = 160 ( divide both sides by - 14 )

x = [tex]\frac{160}{-14}[/tex] = - [tex]\frac{80}{7}[/tex]

x-36+12x=224 due 15 min ago

Answers

Answer:

x = 20

Step-by-step explanation:

Starting equation: x - 36 + 12x = 224

Reorder: 12x + x (as there is no negative sign in front of the x) - 36 = 224

Add common terms: 13x - 36 = 224

Subtract (in this case add) common term to isolate variable: 13x + 36 = 224 + 36

Isolate variable by dividing both sides by 13: 13x = 260

Solve: x = 20

PT = 7x + 3 and TQ = 9x - 5

Answers

Answer:

Solution for 7x-3=9x+5 equation:

x = -4

Step-by-step explanation:

Simplifying

7x + -3 = 9x + 5

Reorder the terms:

-3 + 7x = 9x + 5

Reorder the terms:

-3 + 7x = 5 + 9x

Solving

-3 + 7x = 5 + 9x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-9x' to each side of the equation.

-3 + 7x + -9x = 5 + 9x + -9x

Combine like terms: 7x + -9x = -2x

-3 + -2x = 5 + 9x + -9x

Combine like terms: 9x + -9x = 0

-3 + -2x = 5 + 0

-3 + -2x = 5

Add '3' to each side of the equation.

-3 + 3 + -2x = 5 + 3

Combine like terms: -3 + 3 = 0

0 + -2x = 5 + 3

-2x = 5 + 3

Combine like terms: 5 + 3 = 8

-2x = 8

Divide each side by '-2'.

How many miles can one run in h hours with the speed of 6 miles per hour?

Answers

Hey there! I'm happy to help!

If you run at a speed of 6 mph, you are running 6 miles every hour. This means you multiply the number of hours by six to find your total mileage, which can be written as 6h miles.

Have a wonderful day! :D

The distance cover by runner will be 6h miles.

What is mean by Speed?

The speed of an object is defined as;

⇒ Speed = Distance / Time

Given that;

Time for run = h hour

Speed for run = 6 miles per hour

Now,

Since, We know that;

Speed = Distance / Time

Distance = Speed x Time

Substitute all the values, we get;

Distance = Speed x Time

Distance = 6 x h

Distance = 6h miles.

Thus, The distance cover by runner will be 6h miles.

Jillian’s school is selling tickets for a play. The tickets cost $10.50 for adults and $3.75 for students. The ticket sales for opening night totaled $2071.50. The equation 10.50 a plus 3.75 b equals 2071.50, where a is the number of adult tickets sold and b is the number of student tickets sold, can be used to find the number of adult and student tickets. If 82 students attended, how may adult tickets were sold?

Answers

Answer: The number of the adult tickets is 168

Step-by-step explanation:

The adults ticket costs $10.50

- The students ticket costs $3.75

- The total money of the opening night is $2071.50

- The equation of the total money earned in the opening night is:

10.50 a + 3.75 b = 2071.50, where a is the number of the adult ticket

 and b is the number of the student ticket

- There were 82 students attended

* Lets solve the problem

∵ 10.50 a + 3.75 b = 2071.50

∵ The number of the students attended is 82

∵ b is the number of the students

∴ b = 82

- Substitute the value of b in the equation

∴ 10.50 a + 3.75(82) = 2071.50

∴ 10.50 a + 307.5 = 2071.50

- Subtract 307.5 from both sides

∴ 10.50 a = 1764

- Divide both sides by 10.50

∴ a = 168

∵ a is the number of the adult tickets

∴ The number of the adult tickets is 168

Answer:

168 Adult tickets were sold
