Answer:
Kendra's daughter is 14 years old.
Step-by-step explanation:
If I'm reading this correctly, it says "plus 7 <em>more</em> years." I'm writing my equation based off that phrase being true.
Set up equation:
Variable x = daughter's age
x × 3 + 7 = Kendra
x × 3 + 7 = 49
3x + 7 = 49
3x = 42
x = 14
Check your work:
14 × 3 + 7 = 49
42 + 7 = 49
49 = 49
Correct!
1.2 + d + 0.4 = 9.7
1.6 + d = 9.7
1.6 (-1.6) + d = 9.7 (-1.6)
d = 8.1
your answer is 8.1
hope this helps

The vehicle be able to cover the full distance of 340km with on petrol tank if the petrol usage is 14 km/1.
Since the vehicles petrol tank has a capacity of 40 litres and the bvehicles wants to cover a distance of 340 with a pertol usage of 14 km/l.
We need to determine if the petrol in the tank will be enough to cover that distance.
<h3>Distance</h3>
So, distance = petrol usage × volume of tank
Since
- petrol usage = 14 km/l and
- volume of tank = 40 l,
Substituting the values of the variables into the equation, we have
distance = petrol usage × volume of tank
distance = 14 km/l × 40 l
distance = 560 km
Since the distance covered = 560 km which is greater than 340 km, the vehicle will be able to cover the full distance.
So, the vehicle be able to cover the full distance of 340km with on petrol tank if the petrol usage is 14 km/1.
