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
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

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.

Caleb solved this equation and recorded his work.
7.4x + 4.1(2x − 4) = −2.3(x − 6) − 21.6
1. 7.4x + 8.2x − 16.4 = −2.3x + 13.8 − 21.6
2. 15.6x − 16.4 = −2.3x + 35.4
3. 17.9x − 16.4 = 35.4
4. 17.9x = 51.8
5. x ≈ 2.89

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

Step-by-step explanation:
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).

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.

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

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.
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

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
