Find the common denominator

It is 6

Multiply everything by 6

2/3*(6)= 4g

1/2 *(6)= 3g

14*(6)= 84

4g +3g = 84

7g= 84


g= 12

the track coach tells Dave that he has 84% of his workout left. Dave has run 4 laps so far. How many laps will Dave run in all
ICE Princess25 [194]
If 4 is 100-84=16 % of his workout, 4 is 16/100 or 4/25 of his workout.  If 4=4x/25, where x is his workout length, dividing by 4 and multiplying by 25 gives x=25, so Dave must run 25 laps total.

230 per hour. multiply 230 by the number of hours to find total posters.

The equation is Total = 230 x hours written as T = 230x, where x is the number of hours.

you have the total, so replace t with the value and solve for x:

1265 = 230x

Divide both sides by 230:

x = 1265 / 230

x = 5.5 hours.

Mean is the average. To find the average, add the four scores together and divide by 4.

The expression is Mean = ( score 1 + score 2 + score 3 + score 4)/4

Replace what is known:

20 = (25 + 15 + 18 + p)/4

Simpligy:

20 = (58 +p) /4

Multiply both sides by 4:

80 = 58 + p

Subtract 58 from both sides:

p = 80 - 58

p = 22
