Hey there!

4x - 9 = 15

ADD 9 to BOTH SIDES

4x - 9 + 9 = 15 + 9

CANCEL out: -9 + 9 because it gives you 0

KEEP: 15 + 9 because it help solve for the x-value.

NEW EQUATION: 4x = 15 + 9

SIMPLIFY IT!

4x = 24

DIVIDE 4 to BOTH SIDES

4x/4 = 24/4

CANCEL out: 4/4 because it gives you 1

KEEP: 24/4 because it gives you the answer of the x-value

NEW EQUATION: x = 24/4

SIMPLIFY IT!

x = 6

Therefore, your answer is: x = 6 (Option D.)

Good luck on your assignment and enjoy your day!

Question
Ahat [919]

Answer:

4 minutes.

Step-by-step explanation:

There are three trains that Rachel has to take to go to her job. The total time is taken by her, on average, 1 hour and 20 minutes i.e. (60 + 20) = 80 minutes.

In his journey, she walks for 15 minutes and a train journey for about 53 minutes.

Then the total waiting time for the trains is (80 - 53 - 15) = 12 minutes.

Therefore, the average waiting time, in minutes, at each of the three train stations will be \frac{12}{3} = 4 minutes. (Answer)

Inequality <br> Choose all answers that apply
maxonik [38]

Hi there!  

»»————- ★ ————-««

I believe your answer is:  

Option A;  m \leq\frac{3}{5}

»»————- ★ ————-««  

Here’s why:  

  • We can use inverse operations to solve for 'm'.

⸻⸻⸻⸻

\boxed{\text{Solving for 'm':}}\\\\5m+1\leq4\\--------\\\rightarrow 5m + 1 - 1 \leq 4 - 1\\\\\rightarrow 5m\leq3\\\\\rightarrow \frac{5m\leq3}{5}\\\\\rightarrow \boxed{m\leq\frac{3}{5}}

⸻⸻⸻⸻

Any number that is less than or equal to the value of three-fifths would work.

The option that is less than or equal to (3/5) is option A.

Assuming that there are more options than the options shown, choose the numbers that are less than or equal to (3/5).

»»————- ★ ————-««  

Hope this helps you. I apologize if it’s incorrect.
