Fill in each blank with an integer (signed number).

Question

(a)
=−−1−7+−1
(b)
=−−51+−5

Answer 1

Let's solve each of the expressions step by step.

(a)

Given expression: \[ -1 - 7 + -1 \]

Step 1: Simplify \[ -1 - 7 = -8 \]

Step 2: Now add -1 \[ -8 + -1 = -9 \]

So, \( (a) = -9 \).

(b)

Given expression: \[ -51 + -5 \]

Step 1: Simplify \[ -51 + -5 = -56 \]

So, \( (b) = -56 \).

Final answers: (a) = -9
(b) = -56

Answer 2

is that correct

Answer 3

Let's double-check the calculations for both expressions.

(a)

The expression is: \[ -1 - 7 + -1 \]

Step 1: Calculate \(-1 - 7\): \[ -1 - 7 = -8 \]

Step 2: Now add \(-1\): \[ -8 + (-1) = -8 - 1 = -9 \]

So for (a), the answer is indeed \(-9\).

(b)

The expression is: \[ -51 + -5 \]

Step 1: Combine the two negative numbers: \[ -51 + (-5) = -51 - 5 = -56 \]

So for (b), the answer is indeed \(-56\).

Both answers were correct: (a) = -9
(b) = -56

Answer 4

are you sure

Answer 5

Yes, let's analyze it once more to ensure accuracy.

(a) The expression is: \[ -1 - 7 + -1 \]

Breaking it down step by step:

1. Calculate \(-1 - 7\): \[ -1 - 7 = -8 \]

2. Add \(-1\): \[ -8 + (-1) = -8 - 1 = -9 \]

So, for (a), the result is \(-9\).

---

(b) The expression is: \[ -51 + -5 \]

Breaking it down:

1. Combine \(-51\) and \(-5\): \[ -51 + (-5) = -51 - 5 = -56 \]

So, for (b), the result is \(-56\).

---

To summarize:

• (a) = -9
• (b) = -56

Both calculations are confirmed as correct. If you have any further doubts or need additional explanations, feel free to ask!
