Answer:
<h3>
The father is 40 and the daughter is 20.</h3>
Step-by-step explanation:
x - the present age of the daughter
2x - the present age of the fathter
x - 10 - the age of the daughter ten year ago
2x - 10 - the age of the fathter ten year ago
Father is older than his dauther, so:
2x - 10 = (x - 10) + 20
2x - 10 = x - 10 + 20
2x - 10 = x + 10 {subtract x from both sides}
x - 10 = 10 {add 10 to both sides}
x = 20
2x = 2·20 = 40
Answer:
x = -4/9
Step-by-step explanation:
-3(4x − 2) = 6x + 14
Distribute
-12x+6 = 6x+14
Add 12x to each side
-12x+6+12x = 6x+14+12x
6 = 18x+14
Subtract 14 from each side
6-14 = 18x
-8 =14x
Divide each side by 14
-8/14 = 14x/14
-4/9 = x
The answer would be C, because time can't be negative and the height of the plant can't go below 1
