40 I believe because the space of the auto mobile catching up to the train is 4 hours. 4 times 30 is 120 miles so u need to figure out a number that can reach 120 in three hours. 3 times 40 is 120

Step-by-step explanation:
<u>Step 1: Define</u>
3 - 4r ≥ 15
<u>Step 2: Solve for </u><em><u>r</u></em>
- [Subtraction Property of Equality] Subtract 3 on both sides: -4r ≥ 12
- [Division Property of Equality] Divide -4 on both sides: r ≤ -3
<u>Step 3: Compare</u>
- Substitute in <em>r</em>: -3 ≤ -3
This is true. -3 is less than <em>or equal to</em> -3.
Answer:
4. option A ---> m = 65h
Step-by-step explanation:
According to the question it states that,
- m --> number of miles traveled.
- h --> <u>over</u> hours
Now if we look at the table we need to find the starting point, or in other words, how much distance traveled in 0 hours. So we would divide miles / hours.
*Four hours, the variable in the question and in the table says n, but the answer choices says h, so I am saying h for hours just if you were wondering on it.*
distance (m) / hours (h)
130 / 2 = 65
195 / 3 = 65
325 / 5 = 65
455 / 7 = 65
So, our starting point, or numbers of miles traveled in 0 hours was 65. Now let us form an equation.
m = 65h
I would appreciate if you give me the brainlist or not. Hope this helps and stay safe, happy, an healthy, thank you :) !!
Answer:
x < -16, none of the solution sets are correct for the given equation.
Step-by-step explanation:
-1/4x > 4, multiply both sides by -4, don't forget when you multiply or divide by a negative you have to flip the sign.
x < -16
none of the solution sets are correct for the given equation.
The answer is 25.
