Your mother bought several full packets of eggs. She opened all the packs and kept all the eggs in the fridge. You later counted all the eggs and found there are 46 eggs. One single packet looks as shown below. Do you think shopkeeper cheated your mother? Justify.
Answers
Answer:
Even when the answer is not complete, most likely yes, she was cheated.
Step-by-step explanation:
The question does not include how a packet looks, however since the total egg count is 46 units, this number is only divisible by 2 and 23.
So unless each egg packet contains 2 or 23 eggs, any other size would mean a packet had less eggs than expected.
Usually eggs come in packs of 6 or 12 units, so to sum 46 eggs or more you would need:
If 6 eggs per packet:
46/6 = 7,66 packets -> she must have bought 8 packets and should have 48 eggs, meaning there are 2 eggs missing.
If 12 eggs per packet:
46/12 = 3,83 packets -> she must have bought 4 packets and should have 48 eggs, meaning there are 2 eggs missing.
That's why it is safe to assume some packets had less eggs than expected.

Alejandra correctly wrote the equation y – 3 = y minus 3 equals StartFraction 1 Over 5 EndFraction left-parenthesis x minus 10 right-parenthesis.(x – 10) to represent a line that her teacher sketched. The teacher then changed the line so it had a slope of 2, but still went through the same point. Which equation should Alejandra write to represent the new line?
Answers
Answer:
The equation Alejandra should write to represent the new line should be
y-3 = 2(x-10)
Step-by-step explanation:
The equation Alejandra wrote for the line her teacher sketched is
y-3 = 1/5 (x-10).
This can be related to the equation of a line in point slope form. The equation of line in point slope form
is
y - y₁ = m (x - x₁)
Where (x₁, y₁) is a point on line
and m is the slope of the line.
Hence, for the equation Alejandra wrote
The line went through point (3,10) and the slope of the line is 1/5.
Now, from the question
The teacher changed the line so it had a slope of 2, but still went through the same point. That is, the line still went through point (3,10).
In the new line the teacher sketched, the values of x₁ and y₁ remain the same but the value of the slope (m) has changed.
The slope of the new line is 2, that is, m =2.
Therefore,
The equation that represents the new line is
y-3 = 2(x-10)
Hence, the equation Alejandra should write to represent the new line should be y-3 = 2(x-10).

Answers
Answer:
1. One solution
2. No solution
Step-by-step explanation:
1.Step 1: Subtract 2x from both sides.
5x+3−2x=2x−3−2x
3x+3=−3
Step 2: Subtract 3 from both sides.
3x+3−3=−3−3
3x=−6
Step 3: Divide both sides by 3.
3x + -6
3 2
x=−2
Answer:
1)One solution
2)No solutions
Step-by-step explanation:
To solve this for the first one you should add both sides by three to get the constants on one side.
5x+3+3=2x
Combine like terms.
5x+6=2x
Get x to one side by subtracting 5x on each side.
6=-3x
Solve for x.
x=6/-3 or x=-2
Which means one solution.
To solve the second one you should o all the steps above, but to find:
8=3
Which is not true, so no solutions.

A boat travled 27 miles in 2 hours. At this rate, how many miles will the boat travel in 1/2 hour ?
Answers
Answer:
54 miles
Step-by-step explanation:
Just divide the 27 miles to the half hour and you will see how many miles the boat travelled. In 27 miles in 2 hours is 13.5 miles so we figured out what we get in two hour so to find out for the half an hour you do the same thing
Answer:
6.75 miles.
Step-by-step explanation:
1/2 is 1/4 of 2 hours, so you'd take 1/4 of 27 (which is 27/4) and you would get 6.75.
If that explanation is a little difficult to understand, let me know and I will rephrase!

Answers
Answer:
15 ounces per box
Step-by-step explanation:
What is the weight, in ounces, of one box?
165ounces/ 11 boxes
This means
165ounces per 11 boxes
Hence:
11 boxes = 165ounces
1 boxes = x ounces
Cross Multiply
11x = 165 × 1
x = 165/11
x = 15 ounces
Therefore, the weight, in ounces, of one box is 15 ounces per box.
Answer:
15 ounces per box
