40+6X = -7(4x+4)
Enter you answer
Answer:
x = -2
Step-by-step explanation:
40+6X = -7(4x+4)
Distribute
40 +6x = -28x -28
Add 28x to each side
40 + 6x +28x = -28x-28 +28x
40 + 34x = 28
Subtract 40 from each side
40 + 34x -40 = -28-40
34x = -68
Divide each side by 34
34x/34 = -68/34
x = -2
Step-by-step explanation:
[tex]40 + 6x = - 7(4x + 4) \\ 40 + 6x = - 28x - 28 \\ 6x + 28x = - 28 - 40 \\ 34x = - 68 \\ \\ x = - \frac{68}{34} \\ \\ x = - 2[/tex]
A skateboard travels 55 feet in 4 seconds. Is the skateboard going faster, slower, or the same speed as the scooter?
Answer:
Slower.
Step-by-step explanation:
I belive it is slower because the scooter was 30 feet per 2 seconds. 30+30+60 feet, 2+2= 4 seconds= 60 feet and 4 seconds which makes the 55 feet per 4 seconds slower.
Jill owns a cupcake shop. In her 2nd month of business, Jill sold 330 cupcakes. In the 6th month, she sold 918 cupcakes. The growth of the business can be modeled by a linear equation.
The linear expression which models Jill's business growth is y = 147x + 36
Sales made by Jill :
2nd month = 330 cupcakes 6th month = 918 cupcakesGeneral form of a linear model :
y = bx + c y = final or predicted amount b = slope or growth rate c = intercept x = number of monthsWe can calculate the amount sold per month :
(6th month sale - 2nd month sale) / Number of months b = (918 - 330) / (6 - 2) = 588 / 4 = 147Using the second month ;
330 = 147x + c
x = 2
330 = 147(2) + c
330 = 294 + c
c = 330 - 294
c = 36
Therefore, the linear model can be expressed thus ;
y = 147x + 36Learn more : https://brainly.com/question/18405415
Identify the segment bisector of MN Then find MN.
????????? Helppp pleaseee
Given:
The figure.
To find:
The segment bisector of MN and value of MN.
Solution:
From the given figure it is clear that ray RP,i.e., [tex]\overrightarrow {RP}[/tex] is the segment bisector of MN because it divides segment MN in two equal parts.
Now,
[tex]3\dfrac{5}{6}=\dfrac{3\times 6+5}{6}[/tex]
[tex]3\dfrac{5}{6}=\dfrac{23}{6}[/tex]
Since, [tex]\overrightarrow {RP}[/tex] is the segment bisector of MN, therefore,
[tex]MN=2\times \dfrac{23}{6}[/tex]
[tex]MN=\dfrac{23}{3}[/tex]
[tex]MN=7\dfrac{2}{3}[/tex]
Therefore, the length of MN is [tex]7\dfrac{2}{3}[/tex].

Answer: It’s C on Edge i think
Step-by-step explanation:
E2021?
The system of linear inequalities is represented by the graph is y > x-2 and x + 2y < 4
Equation of a lineThe formula for finding the equation of a line is expressed as y =mx +b
m is the slope
b is the y-intercept
For the dashed line (4,0)and (0,2)
Slope = 2/-4
Slope = -1/2
The equation is y = -1/2x + 2 = 2y =-x + 4
The inequality equation will be x + 2y < 4
The system of linear inequalities is represented by the graph is y > x-2 and x + 2y < 4

Answer:
x = 6, y =-2
Step-by-step explanation:
5x+2y = 26
3x+2y = 14
Subtract the two equations to eliminate y
5x+2y = 26
-3x-2y = -14
---------------------
2x = 12
Divide by 2
2x/2 = 12/2
x = 6
Now find y
3x+2y = 14
3*6+2y = 14
18+2y = 14
Subtract 18 from each side
18+2y-18 =14-18
2y = -4
Divide by 2
2y/2 = -4/2
y = -2
Answer:
x=6
y=-2
Step-by-step explanation:
5x+2y=26
3x+2y=14
subtract
2x=12
x=12/2=6
3(6)+2y=14
2y=14-18=-4
y=-4/2=-2

One restaurant uses 5 quarts of soup to make 20 equal servings. Another restaurant uses 7 quarts of soup to make 25 equal servings. Which restaurant has larger servings of soup? Write division expressions to represent the problem and then solve.
Answer:
2nd restaurant
Step-by-step explanation:
Provided first restaurant uses 5 quarts of soup, and that total of 5 quarts of soup is equally divided in 20 bowls.
So each bowl has = [tex]\frac{Total\ quantity\ of\ soup}{total\ number\ of\ bowls} = \frac{5}{20} = 0.25\ quarts\ in\ each\ bowl[/tex]
On the other hand the second restaurant uses 7 quarts of soup for 25 bowls.
Quantity in each bowl = [tex]\frac{7\ quarts}{25\ bowls} = 0.28\ quarts[/tex]
Since the quantity of soup is more in each bowl of second case that is 0.28 quarts, it serves more soup.

Write the equation of a function whose parent function, f(x)= x + 6, is shifted 4 units to the right. Og%) = x - 10 O g(x)=-4 Og%) = x + 2 Ogl/)=+ 10
Given:
The parent function is
[tex]f(x)=x+6[/tex]
To find:
The equation of a function whose parent function, f(x)= x + 6, is shifted 4 units to the right.
Solution:
If parent function f(x) is shifted a units to the right to get the function g(x), then
[tex]g(x)=f(x-a)[/tex]
Here, a=4 units.
[tex]g(x)=f(x-4)[/tex]
[tex]g(x)=(x-4)+6[/tex] [tex][\because f(x)=x+6][/tex]
[tex]g(x)=x+2[/tex]
Therefore, the required function is [tex]g(x)=x+2[/tex] and option C is correct.

The Millers receive a dinner bill for $122.75. The sales tax rate is 8%. They want to leave an 18% tip on the total bill after tax. How much money will they pay for their dinner with tax and tip?
Answer: 156.43
Step-by-step explanation:
Millers receive a dinner bill for $122.75. The sales tax rate is 8%. They want to leave an 18% tip on the total bill after tax. Then he pay 156.43 on total bill.
What is Percentage?Percentage, a relative value indicating hundredth parts of any quantity.
Given that,
Millers receive a dinner bill for $122.75.
The sales tax rate is 8%.
8/100=0.08
8% of bill is 0.08×122.75=9.82
After adding tax to the bill we get 122.75+9.82
=132.57.
18% tip on the total bill after tax is added
18/100=0.18
0.18 of 132.57
0.18×132.57
=23.86
The total bill is 132.57+23.86
=156.43
Hence $156.43 will they pay for their dinner with tax and tip.
