Answer:
Step-by-step explanation:
First, let's find the value of x.
Note that the two equations with the x are alternate interior angles. Therefore, their angle measures are equivalent. So, we can write the following equation:
Solve for x. Let's add 38 to both sides:
Subtract 3x from both sides:
Divide both sides by 2. So, the value of x is:
We can see that we have a right triangle.
The sum of the three interior angles of a triangle is always 180. Therefore, we can write that:
Since we already know that x is 17, substitute 17 for x. This yields:
Now, we can solve for y. Multiply:
Combine like terms:
Evaluate:
Subtract 117 from both sides:
Divide both sides by 7. So, the value of y is:
And we're done!
<span>To get my answer, I multiplied
$2075 by 0.3 to get 622.50. Then I subtracted 622.50 from 2075 to get
1452.50.
Hope this helps,

Answer:
17. x = y^2 - 2ay +a^2
18. x = y^2 - a
Step-by-step explanation:
17. Since we want to make x the subject of the formula, we first isolate the square root of x and get
= y - a.
squaring both sides,
x = y^2 - 2ay +a^2
18. Since both x and the a are under the square root, we first start by squaring both sides.
So y^2 = x+a.
Isolating the x, we get
x = y^2 - a
Answer:
Used car have the highest range of 75
Step-by-step explanation:
Yeah the type of car that have the highest range In monthly sales.
we know that
The range is the difference between the highest and the lowest value
First we,
calculate the range in monthly sales for the new car
highest value=51
lowest value=20
range=51-20
range=31
Secondly,we
calculate the range in monthly sales for used car
highest value=87
lowest value=12
range=87-12
range=75
