The correct answer is A) $75.85.
A discount of 20% means that the cost is 80% of the original. 80%=80/100=0.8
0.8(129) = 103.20
A discount of 30% means that the cost is 70% of the amount before discount. 70%=70/100=0.7
0.7(103.20) = 72.24
A sales tax of 5% means that it is 105% of the amount pre-tax. 105%=105/100=1.05
1.05(72.24) ≈ 75.85
Answer:
05.
Step-by-step explanation:
trust me dude i just took this question :D
Easy this answer is going to be 0.517 you can read and round
Slope-intercept form is y = mx +b, where the variable m represents the slope of the line and the variable b represents the y-intercept of the line. Since we weren't given the y-intercept, one way to solve this problem is substitute the slope for the variable m and then the x and y values from the ordered pair to solve for b.
y = mx + b
y = 3x + b
-4 = 3(9) + b
Now, we can simplify by computing the multiplication on the right side of the equation.
-4 = 27 + b
Finally, we can find the value for b by subtracting 27 from both sides of the equation to get:
-31 = b
Now, we should substitute this value for b back into our equation with the slope.
y = 3x - 31
Therefore, your answer is y = 3x - 31.
Hope this helps!
For this case we have the following variables, let:
x: The greater integer
y: The minor integer
We have to:
Thus, we have a system of two equations with two unknowns. To solve, we follow the steps below:
Step 1:
We add both equations:
Thus, the smallest integer is 
Step 2:
We substitute "y" in any of the equations and clear x:
Thus, the largest integer is 
So:
Anwer:
Integer minor,
Integer greater,
