1 |
Problem |
Find the additive and multiplicative inverse of a: |
|
2 |
Step |
Let’s solve for a: |
\$ (1/3) a - 6 \$ = 2 |
3 |
Step |
Add 6 to both sides to isolate \$(1/3)a\$: |
\$ (1/3) a - 6 + 6 = 2 + 6\$ \$ (1/3) a = 8 \$ |
4 |
Step |
Multiply both sides by 3 to solve for a: |
\$ a = 8 \times 3 \$ a = 24 |
5 |
Formula: |
The additive inverse of |
a = -a |
6 |
Step |
Now, the additive inverse of 24 is simply its negative value: |
Additive inverse of 24 = - 24 |
7 |
Formula: |
The multiplicative inverse of |
\$ a \$ = \$ 1/a \$ |
8 |
Step |
Now, the multiplicative inverse of 24 is simply its reciprocal: |
Multiplicative inverse of 24 = \$(1/24) \$ |
9 |
Choice.A |
This is not correct because it doesn’t correctly identify the additive and multiplicative inverses of the given values |
24 and \$(1/24)\$ |
10 |
Choice.B |
This option represents - 24 as the additive inverse and \$1/24\$ as the multiplicative inverse. This aligns with our calculations |
- 24 and \$(1/24)\$ |
11 |
Choice.C |
This option correctly represents - 24 as the additive inverse, but 24 doesn’t represent the multiplicative inverse of a. The correct multiplicative inverse is \$1/24\$ |
- 24 and \$(24)\$ |
12 |
Choice.D |
This option correctly represents - 24 as the additive inverse, but \$1/22\$ doesn’t represent the multiplicative inverse of a. The correct multiplicative inverse is \$1/24\$ |
- 24 and \$(1/22)\$ |
13 |
Answer |
Option |
B |
