400 x .75 = 300
300 x .10 = 30
300 + 30 = 330
The final coat of the GoPro is 330!
Answer:
V = 300x + -70x2 + 4x3
Step-by-step explanation:
Simplifying
V = (20 + -2x)(15 + -2x)(x)
Reorder the terms for easier multiplication:
V = x(20 + -2x)(15 + -2x)
Multiply (20 + -2x) * (15 + -2x)
V = x(20(15 + -2x) + -2x * (15 + -2x))
V = x((15 * 20 + -2x * 20) + -2x * (15 + -2x))
V = x((300 + -40x) + -2x * (15 + -2x))
V = x(300 + -40x + (15 * -2x + -2x * -2x))
V = x(300 + -40x + (-30x + 4x2))
Combine like terms: -40x + -30x = -70x
V = x(300 + -70x + 4x2)
V = (300 * x + -70x * x + 4x2 * x)
V = (300x + -70x2 + 4x3)
Solving
V = 300x + -70x2 + 4x3
Solving for variable 'V'.
Move all terms containing V to the left, all other terms to the right.
Simplifying
V = 300x + -70x2 + 4x3
We are asked to find the number of combinations in which the 4 remaining flowers can be given to 4 flowers.
When she gives the next teacher a flower, there are 4 options. Next, there will only be 3 options since one flower was given away. Next there will be 2 options, and finally there will only be 1 flower left.
This means that there are:
4! = 4 * 3 * 2 * 1 = 24 ways to give the remaining flowers.
The answer is 24.
<u>All you do for this question is cross multiply and divide

360/x = 150%/100
<u>3600/150= 24</u>
x=24<u>
