a) –a + b is negative
b) a – b is positive
c) b-a is negative
Step-by-step explanation:
1. Suppose a and b are real numbers where a > 0 and b < 0.
a. Is –a + b positive or negative. Explain how you know.
We know a > 0 and b < 0. so, let a =6 and b = -5
Putting values:
–a + b
= -(6)+(-5) = -6-5 = -11
So, –a + b is negative
b. Is a – b positive or negative? Explain how you know.
We know a > 0 and b < 0. so, let a =6 and b = -5
Putting values:
a - b
=6-(-5) = 6+5 = 11
So, a – b is positive
c. Is b – a positive or negative. Explain how you know
We know a > 0 and b < 0. so, let a =6 and b = -5
Putting values:
b-a
=(-5)-(6)
= -5-6
= -11
So, b-a is negative

Answer:
The answer is at 8:00 o’clock.
Step-by-step explanation:
So the Martinez family started 30 min after the Smith’s family. Smith’s family started one hour before Carson’s family. So it means the Smith’s family started at 7:30 and Martinez family started 30 min later. It means at 8:00 o’clock.
Answer:
(16)(1) => identity property of multiplication
2(3+7) = 2(3) + 2(7) => distributive property
(2+6) + 3 = 2+ (6+3) => associative property
9+0 = 9 => identity property of addition
8 x 4 = 4 x 8 => commutative property
Step-by-step explanation:
<u>Step 1: Add the numbers: 9.5 +6.2 = 15.7</u>
<u>Step 2: Subtract the numbers: 15.7 - 12.25 = 3.45</u>
<u>Step 3: Multiply the numbers: 8.6 × 3.45 = 29.67</u>
<u />

<u />
- To solve this equation, the first step is to add the numbers 9.5 + 6.2 into the equation and it will lead to 15.7 as the number for step one.
- To solve this equation, the second step is to subtract the numbers 15.7 - 12.25 into the equation and it will lead to 3.45 as the answer.
- To solve this equation, the third step is to multiply the numbers 8.6 x 3.45 into the equation and it will lead 29.67 as the final answer for the whole equation.
Answer:
Hope this helps.
