SAS
=========================================
Explanation:
SAS = side angle side
One pair of congruent sides is AC = CE (single tickmark). That takes care of one "S" of "SAS".
The other pair of congruent sides is BC = CD (double tickmark). This takes care of the other "S" of "SAS". The order of the "S" terms doesn't matter as long as the angles are between those sides.
The congruent pair of angles is angle ACB = angle ECD. Vertical angles are always congruent. Since we have a pair of congruent angles, this takes care of the "A" of "SAS". The angles are between the sides mentioned in the previous paragraphs.

Solve each system of equations using the elimination method
3x+4y=23
3x-2y=11
Answer: (x,y) = (5,2)
In other words, x = 5 and y = 2
====================================================
Explanation:
Subtract the equations straight down.
The x terms subtract to 3x-3x = 0x and they go away (hence the term "elimination").The y terms subtract to 4y-(-2y) = 6yThe right hand sides subtract to 23-11 = 12We end up with 6y = 12 which solves to y = 2 after dividing both sides by 6.
Now use this y value to find x.
If we used the first equation, then we have these steps
3x+4y = 23
3x+4(2) = 23
3x+8 = 23
3x = 23-8
3x = 15
x = 15/3
x = 5
Or we could use the second equation
3x-2y = 11
3x-2(2) = 11
3x-4 = 11
3x = 11+4
3x = 15
x = 15/3
x = 5
We get the same x value either way.
The solution is (x,y) = (5,2)
To check the answer, plug those coordinates into each equation. After simplifying, you should get the same number on both sides.
------------------
Check:
3x+4y = 23
3(5)+4(2) = 23
15+8 = 23
23 = 23 .. that works
and,
3x-2y = 11
3(5)-2(2) = 11
15 - 4 = 11
11 = 11 .. that works as well
Both original equations are true for those x and y values.
The solution is fully confirmed.

In a city, 49% of the adults are male. Of the adults, 24% are male and rent action-movie DVDs and 10% are female and rent action-movie DVDs.
If an adult is randomly picked, the probability that the person rents action-movie DVDs, given that the person is female, is
.
Answer:
I getting the probability of the adult female that will rent the action movies in DVDs in by dividing the possible probability outcome which is 10% of all adults by the total number of possible outcome. So all of the population of the female is 51% and the ones who rent is only 10%. the probability is 19%
The solution is, 0.20 is the probability that the person rents action-movie DVDs, given that the person is female.
What is probability?Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.
here, we have,
given that,
Data:
A: the adult is a male, P(A) = 0.49
B: the adult rent action-movie DVDs
C: the adult is a female, P(C) = 1 - P(A) = 1 - 0.49 = 0.51
24% of the adults are male and rent action-movie DVDs, then P(A ∩ B) = 0.24
10% of the adults are female and rent action-movie DVDs, then P(C ∩ B) = 0.10
The conditional probability of B (the adult rents action-movie DVDs) given C (the adult is female) is computed as follows:
P(B|C) = P(C ∩ B)/P(C)
= 0.1/0.51
= 0.2
Hence, The solution is, 0.20 is the probability that the person rents action-movie DVDs, given that the person is female.

WHAT IS THE VALUE OF X?
Answer:
x = 20
Step-by-step explanation:
180 - 45 = 5x + 35
180 - 45 = 135
5x + 35 = 135
5x + 35 - 35 = 135 - 35
5x = 100
5x/5 = 100/5
x = 20
Answer:
x=20
Step-by-step explantion:
180-45=135
we have,
135=5x+35
135-35=5x
100=5x
100/5=x
20=x
Raul works at a movie theatre. The function f(x) represents the amount of money Raul earns per ticket, where x is the number of tickets he sells. The function g(x) represents the number of tickets Raul sells per hour, where x is the number of hours he works. Show all work to find f(g(x))
Answer:
Step-by-step explanation:
Function f(g(x)) is the amount of money Raul earns per ticket sold.
here are the steps to find f(g(x)):
Define the functions f(x) and g(x).
f(x) = amount of money Raul earns per ticket
g(x) = number of tickets Raul sells per hour
Substitute g(x) for x in the function f(x).
f(g(x)) = amount of money Raul earns per ticket * number of tickets Raul sells per hour
Simplify the expression.
f(g(x)) = amount of money Raul earns per ticket * number of tickets Raul sells per hour
= amount of money Raul earns per ticket sold
Therefore, f(g(x)) is the amount of money Raul earns per ticket sold.
Here is an example:
Let's say f(x) = $10 and g(x) = 2 tickets/hour. If Raul works for 1 hour, he will sell 2 tickets and earn $20.
f(g(x)) = f(2) = $10 * 2 = $20

Use the sketch below and determine how many squares will be in Step 4.
From step 1 to step 2 they added 3 squares.
From step 2 to step 3 they added 5 squares.
Each step they add the next odd number in sequence: 3,5,7,9,etc.
So for step 4 they would add 7 more squares. Add 7 to the number of squares in step 3 for total squares:
7 + 9 = 16
step 4 will have 16 squares.

A truck, moving continuously, averages 55.5 mph for 6.75 hr. How far does it travel during this time?
Answer:
Distance = speed * time
You are given both the speed and the time so you can find the distance

In the given figure, find the value of x and y?
Answer:
x = 6 cmy ≈ 14.5°Step-by-step explanation:
The given diagram shows two points labeled B. Rename the one on segment CD as E.
We assume that AE is supposed to be the bisector of angle A. Since triangle ABC is isosceles, segment AE will be perpendicular to BC. In that case, triangle EBC is also isosceles, which means BE is also 6 cm.
Angle ABC is exterior to triangle BCD, so has a measure that is the sum of angles BDC and BCD. That is, angle ABC is 2y+y=3y. Angle CBE is also y, so angle ABE will be 3y+y=4y. This exterior angle to triangle BED is the sum of angles BED and BDE. We know BDE is 2y, so BED is 4y-2y=2y, which means triangle BED is isosceles and BD=BE=EC=x=6 cm.
__
Finding the measure of angle y is a bit tricky. We know that angle ABC is 3y, and angle EBC is y. If we say X is the midpoint of BC, where AE crosses BC, then we can write the trig relations ...
BX=BA·cos(3y)
BX=BE·cos(y)
Filling in the measures of BA and BE, we can equate expressions for BX to get ...
8cos(3y) = 6cos(y)
Using the trig identity for cos(3y), we can write this as ...
8(4cos(y)³ -3cos(y)) = 6cos(y)
32cos(y)³ -30cos(y) = 0
2cos(y)(16cos(y)² -15) = 0
This has solutions cos(y)=0 and cos(y) = ±√(15/16). We are interested in the positive solution only:
y = arccos(√15/16) ≈ 14.478°
The value of y is about 14.5°.

Answer:
x = 2, y = -1
(x,y) = > (2,-1)
Step-by-step explanation:
2x + 5y = -1
3x + 2y = 4

2(3x + 2y = 4) = > 6x + 4y = 8
-6x - 15y = 3
6x + 4y = 8
-11y = 11
/-11 /-11
y = -1
2x + 5y = -1
2x + 5(-1) = -1
2x -5 = -1

2x = 4

x = 2
