Answer:
19
20
21
Explanation:
Givens
Let the first integer = x - 1
Let the second = x
Let the third = x + 1
Equation
x - 1 + x + x + 1 = 3x
Solution
3x = 2(x + 1) + 18 Remove the brackets
3x = 2x + 2 + 18 Combine the terms on the right
3x = 2x + 20 Subtract 2 x from both sides
x = 20
x - 1 = 19
x +1 = 21
Check
Sum = 60
2*Largest number = 42
18 more than 42 = 60

Answer: either A or D but i'm pretty sure that it's D
Explanation:
By using a woodstove, the kilograms of wood required to
heat a room to 20°C is 3 kg
<h3>Efficiency of a machine</h3>
- Efficiency is the percent of work put into a machine (input work) to that of the work done by the machine (output work).
- Efficiency of a machine is always less than 100% because the output work is always less than the input work because some of the input work is used to overcome friction.
Efficiency = work output/work input * 100%
Efficiency of fireplaces = 15%
Amount of food required to heat a room to 20°C = 15 kg
Assuming efficiency of 100%, amount of wood required will be X kg:
X = 15% * 15 kg
X = 2.25 Kg
By switching to woodstoves which are 75% efficient, amount of wood required will be Y kg:
Y = 2.25 kg / 75%
Y = 3 kg
Therefore, by using a woodstove, the kilograms of wood required to
heat a room to 20°C is 3 kg
