Answer:
$36.94
Step-by-step explanation:
Okay, so. This is what we do. There is two magazines and they cost 9.95 each multiply 9.95 times 2
9.95 x 2 = 19.90
Okay, then he buys a book for 14.95 we add 19.9. and 14.95
19.90 + 14.95 = 34.85
Then we have a sales tax of 6% we would multiply 34.85 time 6%
34.85 x 6% = 2.09
Then we would add. 34.85 + 2.09
34.85 + 2.09 = 36.94
Therefore your answer is $36.94
Hope this helps!!!
Answer:
12 = 22 × 3
Step-by-step explanation:
You gotta remember that
means
.
So, in this case, f(x) is [4x - 3], g(x) is [x^3 + 2x].
So that : f(x)-g(x) = [4x-3] - [x^3+ 2x] = -x^3 + 4x - 2x - 3 = -x^3 + 2x - 3
Let's solve this system of equations through substitution.
We have these two equations.
-7x-2y=14
6x+6y=18
Now let divide the second equation by 6.
6x+6y=18 ----> x+y=3
Next, let us move y to the right side of the equation.
x+y=3 -------> x=3-y (x equals 3-y)
Because we found out that what x is in terms of y, we can input that in for every instance of x in this equation below.
-7x-2y=14 becomes -7(3-y)-2y=14 (Why? Because x equals 3-y!)
We have a one variable equation now and can solve for y.
-7(3-y)-2y=14
-21+7y-2y=14
5y=35
y=7
Plug in 7 for y in any equation to find x.
x+y=3
x+7=3
x=-4
answer: x=-4, y=7
Answer:
24 ft²
6 × 3 + (½ × 4 × 3)
Step-by-step explanation:
Split shape into a rectangle and triangle;
The rectangle is 6 by 3 ft, the area can be found by multiplying the 2 dimensions:
6 × 3 = 18
The triangle has base 4 ft, the total length of the shape (10 ft) take the 6 ft that is part of the rectangle;
The height is 3 ft;
The area us found by ½ × base × height:
½ × 4 × 3 = 6
Add this together to get the total area.
