In order to get the total price, we can multiply the 4 dollars by .05 to find 5 percent of the object's cost and add it to the sales tax. So, .05 times 4 is 0.2, meaning there is a sales tax of 0.2 dollars. We add that to the four, so the total price is 4.20 dollars. Hope this helps.
Answer:
x = 
Step-by-step explanation:
Since it will be easier, just set "ce" as one term. Let ce = y
You are solving for the variable, x. Note the equal sign, what you do to one side, you do to the other.
Do the opposite of PEMDAS.
First, subtract 4 from both sides:
y = 7x + 4
y (-4) = 7x + 4 (-4)
y - 4 = 7x
Next, Divide 7 from both sides:
(y - 4)/7 = (7x)/7
(y - 4)/7 = x
x = (y/7) - (4/7)
Your value of x is

Answer:
C. JKM is not a right triangle because KM ≠ 15.3.
Step-by-step explanation:
We can see from our diagram that triangle JKM is divided into right triangles JLM and JLK.
In order to triangle JKM be a right triangle
.
We will find length of side KM using our right triangles JLM and JLK as
.
Using Pythagorean theorem in triangle JLM we will get,


Now let us find length of side KL.


Now let us find length of KM by adding lengths of KL and LM.

Now let us find whether JKM is right triangle or not using Pythagorean theorem.



Upon taking square root of both sides of equation we will get,
We have seen that KM equals 18.2 and in order to JKM be a right triangle KM must be equal to 15.3, therefore, JKM is not a right triangle and option C is the correct choice.
Answer:
- x³ + x² + x - 3
Step-by-step explanation:
(3x³ + 2x - 3) - (4x³ - x² + x)
3x³ + 2x - 3 - 4x³ + x² - x
3x³ - 4x³ + x² - x + 2x - 3
- x³ + x² + x - 3
