Answer:
m > -5
Step-by-step explanation:
Divide your inequality by the coefficient of m, which is -3. Doing that requires you reverse the comparison symbol:
(-3m)/(-3) > (15)/(-3)
m > -5
_____
The comparison symbol is reversed whenever an inequality is multiplie or divided by a negative number. You might be able to see why when you look at the relation between a couple of integers:
-2 < -1
2 > 1 . . . . . . multiply the above by -1
Multiplying by a negative number effectively reflects the comparison across the center of the number line. As we know from looking in a mirror; reflection reverses left and right, so numbers that were farther to the right (more positive) are now farther to the left (more negative).
Answer:
11.1m/s
Step-by-step explanation:
Given parameters:
Distance of store = 5miles
Time to store = 
hr
Time from store = 
hr
Unknown:
Average speed = ?
Solution:
Average speed is the total distance divided by the total time taken.
Average speed = 
Total distance = distance to store + distance from store = 5 + 5 = 10miles
Total time taken = hr + hr = 
hr
Average speed = 
= 10 x 
= 11.1m/s
Answer: (c)
Step-by-step explanation:
Given
length of two sides of a triangle is 6 cm and 11 cm
In a triangle length of the third side lies between the sum and subtraction of the other two sides
Suppose x is the length of the third side so
Answer:
Fastest to slowest = 6.08 > 6.4 > 6.72 > 6.75 > 7.03
Step-by-step explanation:
The person who completes the 50-meter race within the shortest possible time is the fastest sprinter. Here, the third sprinter crossed the line in 6.08 seconds, whereas the 4th sprinter crossed the line in 7.03 seconds. That is why the third sprinter has won the race, and he becomes the fastest. On the contrary, the fourth person takes the most time to complete the race, meaning he is the slowest.
Answer:
O. All Real Numbers
Step-by-step explanation:
4(a+3)=12+4a
1) Distribute 4(a+3):
4a+12=12+4a
These values are exactly the same, meaning all real numbers will work!
