Step-by-step explanation:
in wxy x=y, wx= 9x-11, xy= 4x-1, and wy= 7x-3, find x and the measure of each side
Answer:
WX = WY
9x - 11 = 7x - 3..........Then subtract 7x to the other side such that
2x - 11 = -3..........Then add 11 to both sides such that
2x = 8...........Then divide 2 such that
x = 4
Now we can find each side such that
WX = 9(4)-11 = 25
WY = 7(4)-3 = 25
XY = 4(4)+1 = 17
The value of x is 4 and the length of side WX is 25, WY is 25 and XY is 15 and this can be determined by using the given data and arithmetic operations.
Given :
Triangle WXY.Angle x [tex]\cong[/tex] Angle yWX = 9x -11XY = 4x-1WY = 7x-3Given that Angle x [tex]\cong[/tex] Angle y then according to properties of triangle WX = WY.
WX = WY
9x - 11 = 7x - 3
2x = 8
x = 4
Now, put the value of x in the given data in order to find the length of each side.
WX = 9(4) - 11 = 25
XY = 4(4) - 1 = 15
WY = 7(4) - 3 = 25

Answer:
slope: 0.10
Step-by-step explanation:
The independent variable is the number of texts, so that goes in the denominator of the slope ratio.
slope = (change in cost)/(change in texts)
= ($30 -25)/(100 -50)
= $5.00/50
slope = $0.10 per text
whats 6x + 7y - 5 when x = 2 and y = 3
Answer:
28
Step-by-step explanation:
Plug into equation
Answer:
Well if x = 2 and y = 3 then that would be 28
Step-by-step explanation:
First replace the x with 2 and multiply it with 6 getting 12 and then do the same with 7y and turn the y into 3 multiply it getting 21 then you add that with the 12 we got and get 33 then subtract it by that 5 and finish with 28!

Alexia, Benito, and Carmen won a team art competition at their local park. As
part of their prize, they can paint the 5 km (5000 m) paved path through the
park any way they like.
They decided Alexia will paint the first 70 m, then Benito will paint the next
15 m, then Carmen will paint the next 35 m. They will keep repeating this
pattern until they reach the end of the 5 km path.
What percentage of the path will each person paint?
Answer:
Alexa: 58.8%
Benito: 12.5%
Carmen: 28.7%
Step-by-step explanation:
(70m + 15m + 35m)x=5000
x=41.67 times
41x120m=4920m, leaving 80 m which Alexa and Benito got an extra time.
Alexa painted 42 times
Benito painted 41.67 times
Carmen painted 41 times
Alexa: 42x70m=2940m, 2940/5000=58.8%
Benito: 41.67x15m=625m, 625/5000=12.5%
Carmen: 41x35m=1435m, 1435=/5000=28.7%
Why must you perform the same operation on both sides of the equation when isolating the variable
Answer:
You must perform the same operation on both sides of the equation when isolating the variable in order to keep the equation balanced.
Step-by-step explanation:
According to the properties of equality, you must perform the same exact operation to each side of the equation, so you must also subtract from to keep the equation balanced.

Adventure play sells an mp3 for 18.00 and charges $3.25 per song. King music sell a player for $23.00 and charges $2.00. For how many songs will the cost be the same
Answer:
4 songs
Step-by-step explanation:
Given data,
Adventure play sells mp3 = $18
Charges per song = $3.25
King music sell Mp3 = $23
Charges per song = $2
Let number of songs be Y, then we can calculate by using following method,
Adventure play MP3 cost + charges per song = Kings Music MP3 cost + charges per song
By putting the value, we get
$18 + $3.25 Y = $23 + $2 Y
By solving the equation,
$3.25 Y - $2Y = $23 - $18
$1.25 Y = $5
Y = $5 ÷ $1.25
Y = 4 songs
Hence, for 4 songs the cost be same.

John has 8 less nickels than dimes. If there is $8.30 in the purse, which equation could be used to determine the number of each type of coin?
So we know that John has 8 less nickels than dimes.
10¢= one dime
5¢= on nickel
8x5=40
Multiply 8 with 5 first because you know John hase 8 less nickels than dimes.
Subtract $8.30 with 40¢. Answer: $7.90. $7.90 divide 10 is 79 so then the left over is 0.
Final result: 79 dimes and 8 nickels.
Given: y = 3x - 4. What is the x-intercept? (0, -4) ( 4/3 , 0) (0, 4/3 )
This equation is in slope-intercept form of y = mx + b form.
The m represented by the coefficient of the x term
represents the slope and b represents the y-intercept.
So our y-intercept is -4 and we can write this as the ordered pair (0, -4).

It is larger than 199,999 and it is a multiple of 2.
How many different numbers could he have picked?
Answer:
Step-by-step explanation:
The biggest 6 digit number is 999,999. If it is a multiple of 2, then the largest one is 999,998.
A number that is larger than 199,999 and is a multiple of 2 is 200,000
Every 100,000 there are 50,000 even numbers
so the answer is 349999

A cable company uses the formula S = 20,000 (1 + 0.08)y to estimate the number of subscribers, S, that use their service after y years. If there were 20,000 cable television subscribers when the cable company began, what is the meaning of the expression (1 + 0.08)Y?
Options :
A. Every year the number of subscribers is estimated to increase by 8 over the number
of subscribers the year before.
B. Every year the number of subscribers is estimated to increase by 8% of the original
20,000 subscribers
C. Every year the number of subscribers is estimated to increase by 8% over the
number of subscribers the year before.
D. Every year the number of subscribers is estimated to increase by 80% of the
original 20,000 subscribers.
Answer:
C. Every year the number of subscribers is estimated to increase by 8% over the
number of subscribers the year before.
Step-by-step explanation:
Given that:
The formula represents an exponential function :
S = 20,000 (1 + 0.08)^y
General form of an exponential equation :
y(x) = ab^x
Where a = initial value ; b = rate of change ; x = time
Comparing the formula given with the general equation:
a = 20000 = Number of subscribers when company began
b^x = (1 + 0.08)^y = percentage increase in the number of subscribers over y years
b) Find the value of 2^-3 x 3^-2

Answer:
x = – ⅓
Step-by-step explanation:
The solution to the expression can be obtained as follow:
–3.1x + 7 – 7.4x = 1.5x – 6(x – 3/2)
Clear bracket
–3.1x + 7 – 7.4x = 1.5x – 6x + 9
–3.1x – 7.4x + 7 = –4.5x + 9
–10.5x + 7 = –4.5x + 9
Collect like terms
–10.5x + 4.5x = 9 – 7
–6x = 2
Divide both side by –6
x = 2 / –6
x = – ⅓
Thus, the solution to the equation is –⅓

Step-by-step explanation:
A customer orders a round of coffee for her friends. If she orders two 12-ounce cups and one 16-ounce cup, she will owe the coffee shop $10.75. If she orders one 12-ounce cup and two 16-ounce cups, she will owe the coffee shop $11.30. What is the cost for a 16-ounce cup of coffee? A.$3.29 B.$4.25 C.$3.40 D.$3.95
Answer:
D.$3.95
Step-by-step explanation:
Let us represent
12-ounce cup = x
16-ounce cup = y
A customer orders a round of coffee for her friends.
If she orders two 12-ounce cups and one 16-ounce cup, she will owe the coffee shop $10.75.
Hence:
2x + y = 10.75.....Equation 1
y = 10.75 - 2x
If she orders one 12-ounce cup and two 16-ounce cups, she will owe the coffee shop $11.30.
Hence:
x + 2y = 11.30.....Equation 2
We substitute 10.75 -2x for y in Equation 2
x + 2(10.75 - 2x) = 11.30
x + 21.50 - 4x = 11.30
Collect like terms
x - 4x = 11.30 - 21.50
-3x = -10.20
x = -10.20/-3
x = $3.40
Solving for y
y = 10.75 - 2x
y = 10.75 - 2($3.40)
y = 10.75 - 6.8
y = $3.95
Therefore , 16-ounce cup is represented by y, the cost for a 16-ounce cup of coffee is $3.95
Option D is correct
