Step-by-step explanation:

[tex]\left(15-9\right)^2\div \left(5+4\right)[/tex]

Using PEMDAS, we solve the brackets first.

[tex]6^2\div \left(5+4\right)[/tex]

[tex]6^2\div \:9[/tex]

Then, we solve the exponents.

[tex]36\div \:9[/tex]

Finally, we divide.

[tex]4[/tex]

Answer 2

Answer:

4

Step-by-step explanation:

you do what is in the parentheses  first so 15-9=6 and 5+4=9 so whats left is the exponent. The exponent is 2 so what is 6x6=36 divided by 9 =4

Hope this helps

a water tank is draining at a constant rate if after five minutes the tank is drained by 4.5 gallons what is the rate in gallons per minute at the tank is draining

Answers

Answer:

The rate is 0.9 gallon per minute

Step-by-step explanation:

Here, we have 4.5 gallons drained in 5 minutes but we are interested in calculating the rate per minute

Let the amount drained per minute be x

4.5 gallons = 5 minutes

x gallon = 1 minute

Let’s cross multiply;

x * 5 = 4.5 * 1

5x = 4.5

x = 4.5/5

x = 0.9 gallons

What is Equation Modelling?

Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

Given is a flight overbooked by 4 passengers.

Assume that the total capacity of the flight is given by integer x.

Also assume that after over booked by 4 passengers, its capacity is given by integer k. So we can write the equation as -

k = x + 4

Therefore, the integer representing a flight overbooked by 4 passengers is given as -

k = x + 4

Is (5, 2) a solution to the equation y = 8x?

Answers

Hey there! I'm happy to help!

To satisfy this equation, the y value has to be 8 times the x.

If you multiply 5 by 8, you get 40, not 2, so this is not a solution. The point (5,40) would be.

Have a wonderful day! :D

All we need to do is substitute and check.

5 = x

2 = y

y = 8x

2 = 8(5)

2 does not equal 40

Best of Luck!

Can an equation with the variable inside grouping symbols be written as a two step equation

Answers

Answer:

  yes

Step-by-step explanation:

In general, a linear equation with a variable anywhere can be written as a 2-step equation. (It may take several steps to get there.)

Example 1:

  2(3x +3) = 18 . . . original equation with variable in parentheses

  6x +6 = 18 . . . . . 2-step equivalent

Example 2:

  4(x -9) +6 = 3(2x +17) . . . original equation

  4x -36 +6 = 6x +51

  -30 = 2x +51 . . . . . . 2-step equivalent

Answer:

Yes
