Darpana solved the equation s = StartFraction a + b + c Over 3 EndFraction for a. Her steps are shown below: 1. Multiply by 3: s
Harman [31]

Answer:

Option (c) is correct.

Step-by-step explanation:

Given equation is :

s=\dfrac{a+b+c}{3}

The equation can be solved for a as follows :

Step 1.

Cross multiply the given equation

3s=a+b+c

Step 2.

Now subtract b on both sides

3s-b = a+b+c-b

3s-b = a+c

Step 3.

Subtract c on both sides

3s-b-c=a+c-c

⇒ a=3s-b-c

The statement that is true for Darpana is " In step 3, she needed to subtract c rather than divide".

Please help this needs to be done today I'll give brainliest if you're correct
Lapatulllka [165]

Answer:

Simile and personification, explanations below!

Step-by-step explanation:

"Like the straw in her pink lemonade" = simile

A simile compares two things using like or as. In this case, the story compares the bending of the microphone to bending the straw in lemonade.

"Her voice an impostor" = personification

Personification describes a object with human-like qualities or characteristics. In this case, a voice can't actually be an impostor as it is not a living person.
