Answer:
The answer to the question: What is the difference between 4 twenty fives and 3 twenty fives?
The difference is 1 twenty five that is equal to 25
Step-by-step explanation:
We need to know the difference between 4 twenty fives and 3 twenty fives, so:
We have common factor 25, so
-4x + 5 - 5 > 29 - 5
-4x > -24
-4x/-4 > -24/-4
x > 6
What were his two mistakes?
Answer:
-4x > 24
x< 6
Step-by-step explanation:
-4x + 5 > 29
-4x + 5 - 5 > 29 - 5 (subtracted 5 on both sides)
To remove +5, Sam subtracted 5 on both sides. but 29-5 is 24
we always put the sign of greatest number . so its positive
-4x > 24 is correct
-4x/-4 > 24/-4
Dividing both sides by -4 is correct. But when we divide by negative number we need to flip the inequality sign . so > becomes <
x < 6
