What might be 3 reasons that a grocery store would have higher prices on items than another store
Answer:
Different Distributor Pricing. Supermarkets pay different prices for the same product through distributors.The difference in Quality.Different Supplier Deals.The lunch special at Omar's Restaurant is a sandwich, a drink and a dessert. There are sandwiches, drinks, and desserts to choose from. How many lunch specials are possible?
Answer:
the question is incomplete, so I looked for similar questions:
There are 3 sandwiches, 4 drinks, and 2 desserts to choose from.
the answer = 3 x 4 x 2 = 24 possible combinations
Explanation:
for every sandwich that we choose, we have 4 options of drinks and 2 options of desserts = 1 x 4 x 2 = 8 different options per type of sandwich
since there are 3 types of sandwiches, the total options for lunch specials = 8 x 3 = 24
If the numbers are different, all we need to do is multiply them. E.g. if instead of 3 sandwiches there were 5 and 3 desserts instead of 2, the total combinations = 5 x 4 x 3 = 60.

Step-by-step explanation:
Alexa's babysitting business charges a flat rate of $40 per month, plus $10 per hour that she babysits. Nick's babysitting service does not charge a monthly fee, but does charge $50 per hour that he babysits. Write an equation to find the number of hours h for which Alexa and Nick would charge the same amount
Let, after h hours both would charge the same amount.
Money charged by Alexa in h hours :
A = 40 + 10h .... 1)
Money charged by Nick in h hours :
N = 0 + 50h .... 2)
For equal charge :
A = N
40 + 10h = 50h
40h = 40
h = 1 hour
Therefore, Alexa and Nick would charge the same amount at first hour.
Hence, this is the required solution.

Answer:
Angle 1 and Angle 5
Step-by-step explanation:
Since we know that a straight angle is 180 degrees this means that angle 2+5+1 is 1/2 of a full angle. We also know that angle 2 is 90 degrees or a right angle, we can subtract 180 - 90 which equals 90 degrees. Since two complementary angles add up to 90 degrees. This 100% assures us that angle 1 + angle 5 are the two complementary angles.

You know: 13 + 7 = 20. Therefore: 13 + 7 + 2 = 20 + 2. Which Property of Equality was illustrated?
A. Subtraction Property of Equality
B. Multiplication Property of Equality
C. Division Property of Equality
D. Addition Property of Equality
Answer:
Addition Property
Step-by-step explanation:
Because since there are the plus sign there is no x - or a ÷sign so its Addition Property
13 + 7 = 20 ⇒ 13 + 7 +2 = 20 + 2 represents addition property of equality.
What is Equality ?
" Equality means representation of any two quantities using mathematical expression with the sign of 'equals to'."
According to the question,
Given,
13 + 7 = 20
Add '2' both the side of the given equality we get,
⇒ 13 + 7 + 2 = 20 + 2
Add both the sides represents addition property of equality.
Hence, Option(D) is the correct answer.

Use the linear equations to answer the question. Information y equals StartFraction 2 over 3 EndFraction x minus 3 y equals StartFraction negative 3 over 2 EndFraction x plus 2 Question Which statement about the lines is true? Answer options with 4 options A. The lines are the same. B. The lines are parallel. C. The lines are perpendicular. D. The lines intersect but are not perpendicular.
Answer:
C. The lines are perpendicular.Step-by-step explanation:
Given the equation of the lines expressed as:
L1: y = 2/3 x - 3 and L2: y = -3/2 x +2
Comparing to the standard form of equation of a line y= mx+c
The slope of L1 is m1 = 2/3
The slope of line L2 is -3/2
Since their slope are not the same, therefore the lines are not parallel to each other.
For two lines to be perpendicular, the product of their slope is -1.
Let's check for both lines:
Check the product of their slope;
m1m2 =2/3 * -3/2
m1m2 = -6/6
m1m12 = -1
Since the product of their slope is -1, hence the lines are perpendicular to each other.

Y=3/2x
Y= -2/3x
Y= 2/3x
Y= -3/2x
Answer:
y = (2/3)x
Step-by-step explanation:
Note that (0, 0) and (3, 2) are both points on this line. The change in y as we go from (0, 0) to (3, 2) is +2 and the change in x is +3.
The slope of this line is this m = rise/run = 2/3
and so the desired equation is y = (2/3)x

Answer:
[tex](-\frac{2}{7},-\frac{65}{7} )[/tex]
Step-by-step explanation:
By steps in the image:
Step 1:
To eliminate, you need one of the coefficients to be the same in both equations. We will use the term "-6x" found in the first equation.
To get this, multiply the entire second equation by 6 and simplify using the distributive property. The new equation is:
[tex]6x-6y=54[/tex]
Step 2:
Now you need to subtract the first equation and the new version of the second equation. By doing this, the "-6x" in both equations will cancel each other out.
Step 3:
Solve for x in the given equation by:
Dividing both sides by -14Simplify the value of x by dividing top and bottom by 2Step 4:
Solve for y by:
Substitute the value of x into the second equationMultiply both sides of the equation by 7Add 2 to both sides of the equationDivide both sides of the equation by -7Solution:
[tex](-\frac{2}{7},-\frac{65}{7} )[/tex]

The formula for percentage increase I (given as a decimal) of an investment is I=S−PP I = S − P P , where P P is the purchase price and S S is the sale price. You sell a stock at a price of $91, earning a percentage increase of 30%. What was the purchase price of the stock?
Answer:
$130
Step-by-step explanation:
Given:
I = (S − P) / P
where,
P = purchase price and
S = sale price.
What was the purchase price of the stock?
I = 30%
S = $91
I = (S − P)/P
30% = (91 - P) / P
0.3 = (91 - P) / P
Cross product
0.3P = 91 - P
0.3P + P = 91
0.7P = 91
P = 91 / 0.7
P = $130

The test had 25 4-point questions and 10 3-point questions.
Answer:
b
Step-by-step explanation:
The test had '10' 4-point questions and '30' 3-point questions in the math test.
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Sophia’s math test is worth 130 points and has 40 problems.
And, Each problem is worth either 4 points or 3 points.
Now,
Let number of 4 point questions = x
And, Number of 3 point questions = y
Since, There are 40 problems.
So, We get;
x + y = 40 .... (i)
And, Each problem is worth either 4 points or 3 points.
So, We can formulate;
4x + 3y = 130 .... (ii)
Solve equation (i) and (ii) as;
Multiply by 4 in equation (i), we get;
4x + 4y = 160
Subtract from equation (ii),
y = 30
And, x + y = 40
x = 40 - 30
x = 10
Thus, The test had '10' 4-point questions and '30' 3-point questions in the math test.
