A lady came to the market to sell eggs . We first customer bought 1/2 of all her eggs and 1/2 of an egg. Her second customer bought 1/2 of all the remaining eggs and 1/2 of an egg. At this point she had sold all her eggs. So how many eggs did the lady have when she came to the market
Answers
Answer:
3 eggs
Step-by-step explanation:
Let the total number of eggs that the woman brought to the market be represented by x
A lady came to the market to sell eggs.
The first customer bought 1/2 of all her eggs and 1/2 of an egg.
x - (1/2x + 1/2) = y
= 1/2x - 1/2= y
y = Amount of eggs left after the first customer left
Her second customer bought 1/2 of all the remaining eggs and 1/2 of an egg.
At this point she had sold all her eggs.
Hence:
y - (1/2y + 1/2) = 0
y - 1/2y - 1/2
Solving for y
y - 1/2y = 1/2
1/2y = 1/2
y/2 = 1/2
Cross Multiply
2y = 2
y = 1
Solving for x
(1/2x - 1/2) = y
y = 1
1/2x - 1/2 = 1
1/2x = 1 + 1/2
x/2 = 3/2
Cross Multiply
2x = 2 × 3
2x = 6
x = 6/2
x => 3 eggs

What is an equation of the line that passes through the points (4,−1) and (8, 5)? Put your answer in fully reduced form.
HELP PLS
Answers
Answer:
y=2/3x-7
Step-by-step explanation:
The slope intercept formula is
y=mx+b
(m) is the slope (rate of change)
(b) is the y intercept (where the line crosses the y axis [vertical])
We need to find the slope and the y intercept. First we will find the slope.
The formula for slope is y1-y2/x1-x2
In and ordered pair the first value is the (x) and the second is the (y).
(x, y)
We take the (y) of one of the given points and subtract the (y) of the second given point, then divide it by the (x) of one of the given points and the (x) of the other given point.
5-(-1)/8-4
Simplify.
5-(-1) =5+1= 6
8-4=4
6/4 Simplify
3/2 is our slope.
Now we apply out new slope into our y=mx+b
y=3/2x+b
Now we need to find the (b) which is the y intercept.
To do this we need to use one of our given points, you can choose either but for this I'll use (4, -1).
In this ordered pair 4 is the (x) and -1 is the (y)
So replace (y) with -1 and (x) with 4
-1=3/2(4)+b
Now solve as usual.
-1=6+b
subtract 6 from each side
-7=b
b=-7
Put our (m) and (b) into our formula.
y=2/3x-7 is our equation.

At the end of a party, 3/4 cup of dip is left. Jim divides 4/7 of the leftover dip equally between 2 friends. How much dip does each friend get?
Answers
Answer:
First, we need to find the amount of dip that was divided amount the two friends.
We know that it is 4/7 of the left dip
therefore:
amount divided among the two friends = (4/7) x (3/4) = 3/7 of the original amount of dip.
This amount is divided among two friends,
therefore:
amount that each friend gets = (3/7) / (2) = 3/14 = 0.2 of the amount of dip
tell me if this is completely wrong because i'm not good at this
Each friend will get 0.2 of the amount of dip.

Step-by-step explanation:
3/2 is the slope
360 is the b (y intercept)
Answer:
slope m = -60
equation y = -60x + 360
Step-by-step explanation:
to find slope use two points given
(x1, y1) = (6, 0)
(x2, y2) = (0, 360)
m = (360-0) / (0-6) = -60
equation y = mx + b
b is the y intercept at (0,360), b= 360
y = -60x + 360

B.
y = -3x - 13
C.
y = -3x + 13
D.
y = -x - 3
Answers
Answer:
y = -3x + 13
Step-by-step explanation:
y = -3x + 13 is the only formula there that has a slope -3 (as shown in -3x) and is the only one that passes through point 5,-2.
The equation of the line that passes through the point (5, -2) and has a slope of -3 will be y = - 3x + 13. Then the correct option is C.
What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
The slope of the line is given as,
y = -3x + c
The equation of the line is passing through the point (5, -2). Then we have
- 2 = - 3(5) + c
- 2 = - 15 + c
c = 13
The equation of the line that passes through the point (5, -2) and has a slope of -3 will be y = - 3x + 13. Then the correct option is C.

Let the measure of the other interior angle = M
The exterior angle is equal to the sum of the interior angles in a given triangle.
An exterior angle of a triangle has a measure of 80°, and one of the remote interior angles has a measure of 20°.
This means,
M + 20 = 80
Solve for M.
M + 20 = 80
Subtract 20 on both sides.
M = 80 - 20
M = 60
Thus,
