Answer:
Step-by-step explanation:
6f - 1 + 7f - 8 = 6f + 7f - 1 - 8
= 13f - 9
Combine like terms. Like terms have same variable with same power.
Answer:
570 m³
Step-by-step explanation:
The volume of water is the product of flow rate of water and the time taken. We are to get the volume of water used between 6 am and 9 am, that is for 3 hours (9 - 6).
We are given the flow rate at 6 am and the flow rate at 9 am, but this flow rate changes between 6 am and 9 am. To get the estimate of the water used, Let us assume that it flows at the same flow rate as it was at 6 am throughout, hence:

Also, let us assume that it flows at the same flow rate as it was at 9 am throughout, hence:

To get the best estimate of the total volume, let us find the average of the two values, hence:

Answer:
The answer is 
Step-by-step explanation:
∵ √24 = 2√6
∵ 
∵ 
∴ 
Answer:
24
Step-by-step explanation:
4 x 3 = 12
12 x 2= 24
Coefficient is the number infront of the varible being multiplied. In this case 24 is the coefficient, and Q is the variable.
