Answer: Amy(A): D + 12

Doug(D):D

Ginger(G):2D

SumOfAll(S)=208 : Total points / sum of all three friends

(D+12)+D+2D=208

D+12+3D=208 - transpose 12 to the right side

4D=208-12

4D = 196 - divide both sides by 4

D=49

Therefore, Doug scored 49

Doug(D):D

Ginger(G):2D

SumOfAll(S)=208 : Total points / sum of all three friends

(D+12)+D+2D=208

D+12+3D=208 - transpose 12 to the right side

4D=208-12

4D = 196 - divide both sides by 4

D=49

Therefore, Doug scored 49

Answer: The equation is provided below:

x = Doug's points

12 + x = Amy's score

2x = Ginger's score

208 = total points of Doug, Amy and Ginger.

x + ( 12 + x ) + 2x = 208

x + 12 + x + 2x = 208

x + x + 2x = 208 - 12

4x = 196

4x / 4 = 196 / 4

x = 49 (Doug's Score)

Amy's Score:

12 + ( 49 ) = 61

Ginger's Score:

2 * ( 49 ) = 98

49 (Doug's) + 61 (Amy's) + 98 (Ginger's) = 208.

The correct answer for Doug's score is 49.

x = Doug's points

12 + x = Amy's score

2x = Ginger's score

208 = total points of Doug, Amy and Ginger.

x + ( 12 + x ) + 2x = 208

x + 12 + x + 2x = 208

x + x + 2x = 208 - 12

4x = 196

4x / 4 = 196 / 4

x = 49 (Doug's Score)

Amy's Score:

12 + ( 49 ) = 61

Ginger's Score:

2 * ( 49 ) = 98

49 (Doug's) + 61 (Amy's) + 98 (Ginger's) = 208.

The correct answer for Doug's score is 49.

HIGH SCHOOL

In 1996, only 193 people owned cellphones in metropolis. Each year, cell phone use has continuously grown by 58%. How many cellphone users were there in 2008? (Show your work)

For this case we have an equation of the form:

Where,

A: initial amount

b: growth rate

x: time in years

Substituting values we have:

For the year 2008 we have:

Round to the whole whole integer:

Answer:

there were 46714 cellphone users in 2008

Where,

A: initial amount

b: growth rate

x: time in years

Substituting values we have:

For the year 2008 we have:

Round to the whole whole integer:

Answer:

there were 46714 cellphone users in 2008

A = 193e^(0.58*12)

A = 203351 people

A = 203351 people

3/4 divided by 6/1

How ?

KFC

Keep Flip Change

Keep the first fraction

3/4

Flip the second fraction(reciprocal)

6/1 -> 1/6

Change the sign

÷ -> ×

So

3/4 × 1/6

Keep Flip Change

Keep the first fraction

3/4

Flip the second fraction(reciprocal)

6/1 -> 1/6

Change the sign

÷ -> ×

So

3/4 × 1/6

So just flip the second fraction and multiply it by its' reciprocal. So 3/4 multiplied by 1/6 which gives you an answer of 3/24 and you want it in simplest form so the real answer is 1/8.
