Answer:
4
Step-by-step explanation:
Think of it this way. You have 2 sets of 2.
I I (This represents two)
I I (This represents the other two)
When you combine these, you get:
I I I I
If you count the tally marks, your answer is 4.
Answer:
2 + (-7) = (-5)
Step-by-step explanation:
Correct problem and method of solving, just miscounted!
It should be + (-7) instead of + (-6).
This also changes the answer to (-5) instead of (-4).
Remark
The key step is just to subtract 5 from both sides. The pointed of the inequality still points away from the variable and towards the number. As long as that remains true, the correct answer can be found.
Solution
2.7 ≤ b + 5 Subtract 5 from both sides.
2.7 - 5 ≤ b
- 2.3 ≤ b Write with the variable on the left.
b ≥ - 2.3 <<<< answer
