Required
Determine the cost of carpet and installation
First, calculate the area of the carpet
Convert to square yard
The cost is then calculated as:
Answer:
b) Substitute (3x - 5) for y in the second equation.
Step-by-step explanation:
If using the substitution method, then the second choice is the most efficient first step.
<u>What is the substitution method?</u>
The substitution method can be used to solve a system of equations. It is when you isolate any of the variables from one of the equations and then substitute that value into the other equation.
Here, the first equation already has an isolated variable, y. We can then substitute its value into the second equation. Like so:
⇒ 2x + 6y = 20
⇒ 2x + 6(3x - 5) = 20

Answer:
7.41 m/s
Step-by-step explanation:
Force of a car inclined at an angle
F=mg Sin Θ where; m = 2956 kg , g = 9.8m/s² , Θ = 35⁰
F = 2956 x 9.8 x Sin 35 = 16615.82 N
Net force due to friction = 16615.82 - 3080 = 13535.82 N
To calculate acceleration; F= Ma
13535.82 = 2956 x a
a = 4.58 m/s²
From equation of motion
V² = 0 + (2 x 4.58 x 6)
V = 
V = 7.41 m/s
I am not sure if I understand what you are asking completely, but if you are trying to find how many the maximum customers you can have approved by the fire department, you divide 36% by 18, which gives you 2% per person. To get the maximum allowed number of people, you divide 100% by 2%, which gives you 50 people.
