Answer:
S = 935 when t ≤ 7
S = (180t - 325) when t > 7
Step-by-step explanation:
John's weekly salary = $375 + commission on number of cars he sell
Commission for the first seven cars sold = $80 per car
Commission above 7 cars = $180 per car
If John sells t cars each week then commission earned by John
= 80×7 + 180(t - 7)
So the salary for week = 375 + commission
S = 375 + 560 + 180(t - 7)
S = 935 + 180(t - 7)
S = 935 when t ≤ 7
(180t - 325) when t > 7
The answer is 9 fish.
The density (d) is the number of units(n) per volume (V):
d = n/V We know: d = 0.3 fish/ft³. V = 30 ft³ n = ? d = n/V n = d * V n = 0.3 fish/ft³ * 30 ft³ n = 9 fish
Answer:

Step-by-step explanation:
Hey!
The first step to solving this equation would be to subtract 5 from both sides of the equation.
<em>Original Equation :</em>

- 8x + 16 = 5
<em>New Equation {Added Subtract 5 to Both Sides} :</em>

- 8x + 16 - 5 = 5 - 5
Now we solve our new equation.
<em>Old Equation :</em>

- 8x + 16 - 5 = 5 - 5
<em>Solution {Old Equation Solved} :</em>

- 8x + 11 = 0
The next step would be to solve with the quadratic formula.
<em>Quadratic Equation ( 1 ) :</em>

<em>Quadratic Equation ( 1 ) {Solved} :</em>
4 +

<em>Quadratic Equation ( 2 ) :</em>

<em>Quadratic Equation ( 2 ) {Solved} :</em>
4 -

<em>So, our final solutions for the equation

- 8x + 16 = 5 are...</em>
x = 4 + 
<em>and </em>
x = 4 - 
Hope this helps!
