As we can see multiplication of 5 and 1/5 is 1. It is obtained by inverse property of multiplication because according to this if number multiply by its reciprocal is equal to one.
And we can say 1/5 is a reciprocal of 5.
So it is inverse property.
So option b is correct.
Answer:
×=-0.8
Step-by-step explanation:
3×2=6
6+9=15
19x+15=0
subtract 15 from both sides
19x=-15
divide both sides by 19
x=-0.789 which rounds up to -0.8

Step-by-step explanation:
<u>Step 1: Define Equation</u>
4x - 8 = 16
<u>Step 2: Solve for </u><em><u>x</u></em>
- Add 8 to both sides: 4x = 24
- Divide 4 on both sides: x = 6
<u>Step 3: Check</u>
<em>Plug in x into the original equation to verify it's a solution.</em>
- Substitute in <em>x</em>: 4(6) - 8 = 16
- Multiply: 24 - 8 = 16
- Subtract: 16 = 16
Here we see that 16 does indeed equal 16.
∴ x = 6 is the solution to the equation.
