Math HW, please help:
At its maximum speed, a motorboat can travel 10 miles downstream on a river in 20 minutes. It takes 30 minutes for the boat to travel back upstream the same 10 miles, also at maximum speed.
Write a system of two equations that could be used to find the maximum speed of the motorboat in still water. Let b represent the maximum speed of the motorboat in miles per hour and let r represent the speed of the river's current in miles per hour. Convert the times into hours. Solve the system of equations for b and r to determine the boat's maximum speed in still water and the speed of the river's current.

Solve for x: -243 = -9(10 + x)

I will reward Brainliest

Answers

Answer:

x = 17

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to Right

Equality Properties

Step-by-step explanation:

Step 1: Define Equation

-243 = -9(10 + x)

Step 2: Solve for x

Divide -9 on both sides: 27 = 10 + xIsolate x: 17 = xRewrite: x = 17

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Substitute in x: -243 = -9(10 + 17)Add: -243 = -9(27)Multiply: -243 = -243

Here we see that -243 does indeed equal -243.

∴ x = 17 is the solution to the equation.

An equation and the first step in its solution are shown.

Equation: x2 + 3x – 9 = 0

Step 1: x2 + 3x + h = 9 + h

What value of h is used to solve the equation by the method of completing the square?

Answers

Answer:

The answer is either 1.5 or 0.667

Step-by-step explanation:

x2+3x-9=0

x2+3x=9

6x=9

x=1.5

x=667

the value of 'h' used to solve the equation by completing the square method is [tex]\frac{9}{4}[/tex]

Given :

An equation and the first step in its solution are shown.

Equation: [tex]x^2 + 3x -9 = 0[/tex]

Step 1: [tex]x^2 + 3x + h = 9 + h[/tex]

In completing the square method , we take the coefficient of x and divide it by 2 and then square it

coefficient of x is 3

divide it by 2 , so we get [tex]\frac{3}{2}[/tex]

Then we square it [tex](\frac{3}{2} )^2\\\frac{9}{4}[/tex]

Then we add it on both sides of the equation

[tex]x^2 + 3x + \frac{9}{4} = 9 + \frac{9}{4}[/tex]

So, the value of 'h' used to solve the equation by completing the square method is [tex]\frac{9}{4}[/tex]

Jackie needs to save $125 to go to a concert. He has saved $35. He makes $7.50 an hour at his job.

Let x representing the number of hours.

Which equation and solution can be used to show how many hours jackie must work in order to have enough money to go to the concert?

A. 125x + 35 = 750; x = 5.75
B. 35 - 7.5x = 125; x = 6
C. 7.5x + 35 = 125; x = 12
D. 35x + 125 = 750; x = 18

Answers

Answer:

Step-by-step

Answer:

Answer is C

Step-by-step explanation:

First Jackie needs to save $125

y = 125

He already saved $35, this is our constant

He makes $7.50 an hour on his job,

Our variable x is hours

125 = 7.50x + 35

If we solve for x, we get x = 12
