write and solve inequality
17. the speed limit of a highway is 55 miles per hour. a car is traveling at least 65 miles per hour. how many miles per hour m over the speed limit is the car traveling?
A 55-m>equal to 65;m. eqaul to 10
B m+65< equal to 55; m < equal to -10
C 65-m< equal to 55;m< equal to 10
D55+m> equal to 65;m> equal to 10
someone please tell me the answer I do not know it.?
can you take a guess? If you do, I will answer your question. you have to try first! :)
D55+m>equal to 65;m>equal to 10
To solve this inequality, we need to determine the value of m, which represents the number of miles per hour that the car is traveling over the speed limit.
Given that the speed limit is 55 miles per hour, and the car is traveling at least 65 miles per hour, we can set up the following inequality:
65 > 55 + m
To isolate the variable, we can subtract 55 from both sides:
65 - 55 > m
Therefore, the solution to the inequality is:
m < 10
This means that the car is traveling at a speed that is less than 10 miles per hour over the speed limit. So, the correct answer is option C:
65 - m ≤ 55; m ≤ 10
To solve this inequality problem, we need to set up an equation and solve it.
Let's define the variable "m" as the number of miles per hour over the speed limit that the car is traveling.
The speed limit is 55 miles per hour, and the car is traveling at least 65 miles per hour.
So, to find how many miles per hour over the speed limit the car is traveling, we need to subtract the speed limit from the car's actual speed.
The inequality can be written as: m = car's speed - speed limit
Substituting the given values, we get: m = 65 mph - 55 mph
Calculating, we find: m = 10 mph
Therefore, the car is traveling 10 miles per hour over the speed limit.
The correct answer is A. 55 + m ≥ 65; m ≥ 10.
