Question

S= 1/2gt-4 solve for g

Answer 1

Explanation:

Let's rearrange this for 'g'.

`\sf{S=\cfrac{1}{2}gt-4}`

`\sf{S+4=\cfrac{1}{2}gt}`

`\sf{\cfrac{S+4}{t}=\cfrac{1}{2}g}`

`\sf{2\cdot\bigg(\cfrac{S+4}{t}\bigg)=g}`

`\sf{\cfrac{2(S+4)}{t}=g}`

`\sf{\cfrac{2S+8}{t}=g}`

Answer:

`\sf{\cfrac{2S-8}{t}=g}`

Answer 2

`\sf g = (2S+8)/(t)`

Explanation:

Given:

`\sf S = (1)/(2)gt - 4`

To solve for g:

Add 4 from both sides of the equation.

`\sf S + 4 =(1)/(2)gt - 4 + 4`

`\sf S + 4 =(1)/(2)gt`

Multiply both sides of the equation by 2.

`\sf 2(S +4) = 2 * (1)/(2)gt`

`\sf 2S + 8 = gt`

Divide both sides of the equation by t.

`\sf (2S+8)/(t)=(gt)/(t)`

So,

`\sf g = (2S+8)/(t)`

Therefore, the equation to solve for g is
`\sf g = (2S+8)/(t)`
