A roast beef sandwich costs $6.75. A customer buys multiple roast beef sandwiches. Write an equation that represents the situation. Use x to represent the number of roast beef sandwiches. Then determine how many sandwiches the customer buys.
Amount used for payment: 80$
The change received: $19.25
An equation that represents this situation is _____
The customer buys ____ sandwiches
Please help me with these two questions.
Answer:
1. 6.75x or (6.75, 1)
2. He buys 9 sandwiches.
Step-by-step explanation:
For the first one, we know that he pays $6.75 for each sandwich, so if x equals the number of sandwiches, when written out it would be 6.75x
For the second one, we have to divide it up and solve one step at a time, and when we start solving them, we will find the pieces to figure out the other problems. Let's start with how much he paid. We know that he paid $80, but we have to remember that he got change back. So to find out how much he truly paid, we subtract the 19.25 from the 80. When we do this, we get 60.75. Now, to find out how many sandwiches he got, we can use how much he paid for each one. We know that he paid $6.75 for each one, and in total he spent $60.75. So to find out, we can simply divide 6.75 into 60.75, and we get 9. So now we know that he bought 9 sandwiches.
I hope this helps :)

She lost $54
Step-by-step explanation: Just trust me
If it was right mark as Brainleist
Answer:
The answer is $54.00.
Step-by-step explanation:
To find the how much money, we just need to multiply 600 by 0.09. 600 x 0.09 = 54.
600
x 0.09
------------
5400
Now you just move the decimal 2 places to the left, and you get 54.00! The answer is $54.00. Hope this helped! :]

An irregular hexagon has angles that measure the following. Angle 1: 2x + 15 Angle 2: 9x - 3 Angle 3: 77 Angle 4: 8x + 8 Angle 5: 13x Angle 6: x - 4 What is the value of x?
Answer: 19
Step-by-step explanation:
1) You combine like terms with all the angles
Ex. 2x + 15 + 9x - 3 + 77 + 8x + 8 + 13x + x - 4, which equals 33x + 93
2) You set up an equation using the formula for the sum of the interior angles
Ex. 33x + 93 = 180(n - 2)
3) Since a hexagon has 6 sides, n is 6
Ex. 33x + 93 = 180(6 - 2)
4) Solve like a regular equation
Ex. 33x + 93 = 180(6 - 2)
33x + 93 = 720
- 93 = - 93
33x = 627
- Divide 627 by 33
x = 19

Answer:
a = -29
Step-by-step explanation:
[tex]12=\frac{a+5}{-2} \\\\-24=a+5\\a=-24-5\\a=-29[/tex]
1st step is to multiply -2 on both sides
Step-by-step explanation:
12× -2 = a+5
-24 = a +5
a = 24+ 5
= 29
What does 1/4 equal for a fraction
Answer: 0.25 as a decimal
Answer:
0.25

Bob has a dollar bill. He uses 1/4 of it to buy a coupon.
Imagine this happening:
1$
Uses 1/4
So... Let's look at what I've given you.
2/4=0.5
3/4=0.75
Well, let's stretch some things a liiiiitle bit.
Bob has a dollar bill blah blah...
We get to 1/4.
Le's make that 2/4.
2/4 is 0.5
So... By stretching the truth
We can infer that
If we put 1/4 back
(Oh no now the word problem creators are mad at me ;) lol)
Anyways, we can infer that by putting 1/4 back
That since 3/4 is 0.75
Then what's connected to 0.5 and 0.75?
The answer, my friend,
Is 0.25

Which is an example of a quadratic function whose axis of symmetry is to the right of the y-axis?
A. y=-x2 - 2x + 1
Answer:
a.
Step-by-step explanation:
imagine a graph that you see, the x-axis has to be positive for it to be on the right side of the y-axis so the value of the y axis can be positive or negative and then you substitute for a positive number, in this case, into the x axis and then you would solve for every answer choice to see if it's right or not if it is accurate.
please help,Explain how solving -7y > 161 is different from solving 7y > -161.

y < -23
7y > -161
y > -23
So, your answer is: -7y > 161 is equal to y < -23, and 7y > -161 is equal to y>-23.

Answer:
x = 28.9
Step-by-step explanation:
tan = [tex]\frac{opposite}{adjacent}[/tex]
⇒ tan 48 = [tex]\frac{26}{x}[/tex]
(tan of 48 is 1.11)
⇒ 1.11 = [tex]\frac{26}{x}[/tex]
multiply 26 on both sides
⇒ 1.11 x 26 = [tex]\frac{26}{x}[/tex] x 26
⇒ 28.86 = x
round to the nearest tenth
⇒ 28.86 = 28.9

An ethanol railroad tariff is a fee charge for shipments of ethanol on public railroads. The Agriculture Marketing Service publishes tariff rates for railroad-car shipments of ethanol in the Biofuel Transportation Database. Assuming that the standard deviation of such tariff rates is $1150, determine the probability that the mean tariff rate of 500 randomly selected railroad-car shipments of ethanol will be within $100 of the mean tariff rate of all railroad-car shipments of ethanol.
Answer:
The appropriate response is "0.9476".
Step-by-step explanation:
The given values are:
Standard deviation,
[tex]\sigma=1150[/tex]
Randomly selected railroad-car shipments,
n = 500
As we know,
⇒ [tex]\sigma \bar{x}=\frac{\sigma}{\sqrt{n} }[/tex]
On substituting the values, we get
⇒ [tex]=\frac{1150}{\sqrt{500} }[/tex]
then,
⇒ [tex]=P(-1.94<Z<1.94)[/tex]
⇒ [tex]=P(Z<1.94)-P(Z < -1.94)[/tex]
On using the table of P, we get
⇒ [tex]=0.9738 - 0.0262[/tex]
⇒ [tex]=0.9476[/tex]

1. The perimeter = 120 m; length = 45 m ; breadth = ____
2. Perimeter of a rectangle = 250 m; breadth = 50m; length = _____
1) to find perimeter we multiply length and breadth so to find breadth we divide the perimeter by the length. which means, 120 divided by 45 and its 62.5 so the answer for the 1st question is 62.5
2. if we multiply length with breadth to find perimeter, just like the first one we divide the perimeter by the breadth. which means, 250 divided by 50 and it will be 5

Nigel drew a parallelogram with a base length of 6 3/4 inches and a height of 2 5/8 inches. Krista made a scale drawing of Nigel's parallelogram using a scale factor of 1/3 .
Answer: Krista's drawing would have a base length of 2 and 1/4 inches and a height of 7/8 inches
Step-by-step explanation: First you do 6 divided by 3 which is 2 then you make 3/4 in twelfths and you get 3/12, then you simplify that into 1/4. Then
you combine those and get a base length of 2 and 1/4 inches.
Next, you do 2 and 5/8 divided by 3. Since 3 is less than 2 your answer would have to be less than 1. What i would do is make 2 and 5/8 into a fraction, which would be 21/8. then to make it easiest you multiply that by 1/3. which would equal 21/24. and then you simplify by dividing that by 3. Which would give you 7/8, which would give you your answer.
So the final answer would be a base length of 2 and 1/4 inches and a height of 7/8 inches.
The graph of the function f(x)=-(x+6)(x+2) is shown below. What statement about the function is true ?
A.) the function is increasing for all real values of x
x < -4.
B.) the function is increasing for all real values of x where
-6 < x < -2.
C.) the function is decreasing for all real values of x where
x < -6 and where x > -2.
D.) the function is decreasing for all real values of x where
x < -4.
Answer:
A
Step-by-step explanation:
in x<-4 the derivative is positive so the function is increasing.
in x>-4 the derivative is negative so the function is decreasing
increasing in (-infinity,-4)
decreasing in (-4,infinity)
