Answer:
Row 1 = 2 white flowers
Row 2 = 3 white flowers
Row 3 = 4 white flowers
Step-by-step explanation:
Instead of having 1.5 times as many pink flowers as white flowers, Molly has decided to plant a garden with twice as many pink flowers as white flowers per row. If she plants 3 rows, with 4, 6, and 8 pink flowers, how can you find the number of white flowers in each of those rows?
Let
White flowers = x
Pink flowers = 2x
Molly plants 3 rows with 4, 6 and 8 pink flowers
Number of white flowers in each row is
Row 1
Pink flowers = 4
2x = 4
Divide both sides by 2
x= 2
White flowers = 2 in row 1
Row 2
Pink flowers = 6
2x=6
Divide both sides by 2
x= 3
White flowers in row 2 = 3
Row 3
Pink flowers = 8
2x=8
Divide both sides by 2
x= 4
White flowers in row 3 = 4
Therefore, the number of white flowers in each rows are 2, 3 and 4 respectively
Answer: The father is 37 years and the son is 7 years
Step-by-step explanation:
Let x represent the present age of the father.
Let y represent the present age of the son.
Three years hence a father will four times as old as his son will be. This means that
x + 3 = 4(y + 3)
x + 3 = 4y + 12
x - 4y = 12 - 3
x - 4y = 9- - - - - - - - - - - - - - - -1
Before two years he was seven times as old as his son was. This means that
(x - 2) = 7(y - 2)
x - 2 = 7y - 14
x - 7y = - 14 + 2
x - 7y = - 12- - - - - - - - - - - - - - -2
Subtracting equation 2 from equation 1, it becomes
3y = 21
y = 21.3 = 7
Substituting y = 7 into equation 1, it becomes
x - 4 × 7 = 9
x - 28 = 9
x = 9 + 28
x = 37
