Question

Which of the following is the missing justification?

Step Justification
one fifth times x plus six equals five Given
x + 30 = 25
x = −5 Subtraction Property of Equality

A Multiplication Property of Equality
B Distributive Property
C Addition Property of Equality
D Division Property of Equality

Answer 1

Answer:

B and C

2. B Multiplication property of equality

3. C Distributive Property

Step-by-step explanation:

1. Given

$\dfrac{1}{5}\cdot x+6=5$

2. Multiply this equation by 5:

$\left(\dfrac{1}{5}\cdot x+6\right)\cdot 5=5\cdot 5$

Multiplication property of equality

3. Use distributive property of equality:

$\dfrac{1}{5}\cdot x\cdot 5+6\cdot 5=25\\ \\x+30=25$

4. Subtract 30:

$x+30-30=25-30\\ \\x=-5$

Subtraction property of equality.

Answer 2

Answer:

No idea what the other person who answered was trying to say since it has to be 1 answer but i think its multiplication because to get 1/5 to be 1 so x you multiply by 5 and it matches because to get 6 to be 30 you multiply by 5 and to get 5 to be 25 you multiply by 5
