The Alternate Exterior Angles Theorem states that, when two parallel lines are cut by a transversal , the resulting alternate exterior angles are congruent.
Given that:
[tex]\begin{gathered} m\angle\text{LRB}=86\degree,\text{ its alternate exterior angle is }m\angle\text{CSK} \\ \\ \text{Therefore,} \\ m\angle\text{CSK}=m\angle\text{LRB} \\ m\angle\text{CSK}=86\degree\text{ (final answer)} \end{gathered}[/tex]what is the value of the expression y - x?
Answer:
[tex]y-x=-10[/tex]
Step-by-step explanation:
In any trapezoid, the sum of all angles is 360°. Additionally, the sum of both angles on the same side of the trapezoid is 180°. Therefore, we know that:
[tex](7x+40)+(68-6y)=180[/tex]
[tex](17y+73)+(121-4x)=180[/tex]
To solve for [tex]x[/tex] and [tex]y[/tex], we must set up a system of equations and solve by substitution, elimination, or graphing.
To start, simplify the first formula, then isolate the [tex]x[/tex] variable:
[tex](7x+40)+(68-6y)=180[/tex]
[tex]7x-6y+68+40=180[/tex]
[tex]7x-6y+108=180[/tex]
[tex]7x-6y=72[/tex]
[tex]7x=72+6y[/tex]
[tex]x=\frac{72+6y}{7}=\frac{72}{7}+\frac{6}{7}y[/tex]
Next, simplify the second formula, then substitute the value above for [tex]x[/tex]:
[tex](17y+73)+(121-4x)=180[/tex]
[tex]-4x+17y+121+73=180[/tex]
[tex]-4x+17y+194=180[/tex]
[tex]-4(\frac{72}{7}+\frac{6}{7}y)+17y+194=180[/tex] (substituted for [tex]x[/tex] here)
[tex]-\frac{288}{7}-\frac{24}{7}y+17y+194=180[/tex]
[tex]-\frac{288}{7}-\frac{24}{7}y+\frac{119}{7}y+\frac{1358}{7}=\frac{1260}{7}[/tex]
[tex]-288-24y+119y+1358=1260[/tex]
[tex]95y+1070=1260[/tex]
[tex]95y=190[/tex]
[tex]y=2[/tex]
Finally, substitute 2 for [tex]y[/tex] in the first formula as simplified:
[tex]7x=72+6y[/tex]
[tex]7x=72+6(2)[/tex]
[tex]7x=72+12[/tex]
[tex]7x=84[/tex]
[tex]x=12[/tex]
Therefore:
[tex]x=12[/tex] and [tex]y=2[/tex]
And the expression [tex]y-x[/tex] equals:
[tex]y-x=2-12=-10[/tex]

Rides, r Cost, c5 $25.506Use the table shown to answer problems10-11.10. A state fair charges $8 for generaladmission and $3.50 for each ride.

Find the cost c for 18 rides.$29.0078$36.0010C= 8 + 3.50rUse the operation symbols in the math palette as needed. Type an equation. Use integers or decimals for anynumbers in the equation.)11. Find the cost c for 18 rides.
We want to know the cost for 7 rides and for 10 rides. We see that for each ride the price increases by $3.50. And thus the price for 7 rides will be:
[tex]29.00+3.50=32.50[/tex]And the price for 10 rides will be:
[tex]36.00+3.50+3.50=39.50+3.50=43.00[/tex]Now, for finding the equation we use that the state fair charges $8 for a general admission, and $3.50 for each ride. This can be written as:
[tex]y=8+3.50x[/tex]where x represents the number of rides.
For example, if we want to know the cost for 18 rides, we replace the value of x by 18, and we get:
[tex]\begin{gathered} y=8+3.50(18) \\ =8+63 \\ =71 \end{gathered}[/tex]Then, the cost for 18 rides is $71.
Yvette maps out several locations in her town, with distances and angles between them. Two triangles are formed within the map.
To conclude that these triangles are congruent by SAS Congruence Postulate, what must the distance between the school and the park be
To be both triangles to be congruent the distance between the school and the park be 1.1 miles.
What is congruence?If two figures are exactly the same in sense of their length side all things then they will be congruent.
If it is possible to superimpose one geometric figure on the other so that their entire surface coincides, that geometric figure is said to be congruent or to be in the relation of congruence.
As per the given two triangles,
The side 2.7 miles is the common side.
The angle is 52 degrees in both triangles same.
To be congruent any one side must be the same by the SAS rule.
Thus, the school-to-park corresponding side is school-to-store.

Answer: area=8cm
Step-by-step explanation:
Answer:
a) Area of shape = 8 square cm.
Step-by-step explanation:
Area of composite shape:
Area of shape = area of rectangle + 2* area of triangle
Rectangle:l = 3 cm ; w = 2 cm
[tex]\sf \boxed{\text{Area of rectangle = l *w}}[/tex]
= 3 * 2
= 6 cm²
Triangle:
b = 2 cm
h = 1 cm
[tex]\sf \boxed{\text{Area of triangle=$\dfrac{1}{2}*b*h$}}[/tex]
[tex]\sf = \dfrac{1}{2}*2*1\\\\\\ = 1 \ cm^2[/tex]
Area of two triangles = 2 *1
= 2 cm²
Area of shape = 6 + 2

16 oz harbor peanut butter for 2.49 or a 64 oz jar of peanut butter for 6.99 round everything up to the nearest cent or hundreth. yes mam
We have to find the "better buy" between two options:
1) 16 oz jar for $2.49
2) 64 oz jar for $6.99
We can compare this two options with the unit price of each one. The unit price will be expressed in "$ per oz" or "$/oz". The option with the smaller unit price is the "better buy".
We can calculate the unit price as teh quotient between the price and the weight of each option.
Unit price for Option 1:
[tex]u_1=\frac{2.49\text{ \$}}{16\text{ oz}}\approx0.16\frac{\$}{oz}_{}[/tex]Unit price for Option 2:
[tex]u_2=\frac{6.99\text{ \$}}{64\text{ oz}}\approx0.11\frac{\$}{oz}[/tex]As the Option 2 (64 oz jar) has a smaller unit price, the better buy is the 64 oz jar for $6.99.
Answer: the better buy is the 64 oz jar for $6.99.

Zeke wants to build a fence around his backyard with the 200 feet (ft) of fencing he bought at Lowe's. Zeke wants to use all of the fencing he bought. he also wants the length of the fencing to be 10 times the width. the equation A=200w-10w^2 can be used to find the area of the garden, where w is the width of the garden, in ft
Considering the vertex of the quadratic equation, the width that will maximize the area of the garden, and the maximum area, are as follows:
Width: 10 ft.Maximum area: 1000 ft².What is the vertex of a quadratic equation?A quadratic equation is defined as follows:
y = ax² + bx + c.
The vertex can be either a maximum point or a minimum point, depending on the coefficient a, as follows:
Maximum: a < 0.Minimum: a > 0.The coordinates of the vertex are given as follows:
x = -b/2a.y = -(b² - 4ac)/4a.For this problem, the equation is:
A(w) = -10w² + 200w.
Hence the coefficients are:
a = -10, b = 200, c = 0.
The width that will maximize the area is:
w = -200/(2(-10)) = 200/20 = 10 ft.
The maximum area is of:
A = -(200)²/(4(-10)) = 1000 ft².
