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'.

x = -4

Simplifying

x = -4

To increase a point by a certain scale factor, you multiply each number inside the point by that scale factors. Ours is 3.

2(3)=6

-4(3)=-12

So, our final point is (6,-12).

The speed for first point is 2/3 miles/min and the speed of second point is 2/3 miles/min.

The four fundamental operations of arithmetic are addition, subtract, multiply, and division of two or more numbers. Included in them is the study of integers, especially the order of operations, which is important for all other aspects of mathematics, notably algebra, information management, and geometry.

As per the provided data in the graph,

The distance for point 1 = 2/3 miles

The time for point 1 = 1 min

Speed = 2/3 miles/min.

Now,

The distance for point 2 = 4/3 miles

The time for point 2 = 2 minutes

The speed will be = 2/3 miles/min.

Answer:

[tex]x>1[/tex]

Step-by-step explanation:

[tex]-3(11 + 6x) < -42 - 9x[/tex]

Expand:

[tex]-33-18x<-42-9x[/tex]

Add 33 to both sides:

[tex]-33-18x+33<-42-9x+33[/tex]

[tex]-18x<-9x-9[/tex]

Add 9x to both sides:

[tex]-18x+9x<-9x-9+9x[/tex]

[tex]-9x<-9[/tex]

Flip the signs (and the symbol)

[tex]9x>9[/tex]

Divide both sides by 9:

Answer:

-48

Step-by-step explanation:

We are given the expression:

[tex]-8y-4x[/tex]

and asked to evaluated when x= -6 and y=9. Therefore, we must substitute -6 in for x and 9 in for y.

[tex]-8(9)-4(-6)[/tex]

Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.

Multiply -8 and 9 ⇔ -8*9= -72

[tex]-72-4(-6)[/tex]

Multiply -4 and -6 ⇔ -4*-6=24

[tex]-72+24[/tex]

Add 24 to -72.

[tex]-48[/tex]

The expression -8y-4x when evaluated at x=-6 and y=9 is equal to -48.

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

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

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.
