Chris bought 2 chicken sandwiches and 3 bowls of vegetable soup for $16.50. Jim bought 1 chicken sandwich and 2 bowls of vegetable soup for $9.50. What was the cost of a bowl of soup? A) $4.50 B) $2.50 C) $5.50 D) $3.25
Answer:
Step-by-step explanation:
This is a system of equations, best solved by using the elimination method. But first we have to come up with our 2 equations that represent the system. Let's call the chicken sandwiches "c" and the bowls of soup "b".
If Chris bought 2 chicken sandwiches and 3 bowls of soup for $16.50, his equation is:
2c + 3b = 16.50
If Jim bought 1 sandwich and 2 bowls of soup for $9.50, then his equation is:
1c + 2b = 9.50
We put these together, one above the other, lining up the variables:
2c + 3b = 16.50
1c + 2b = 9.50
If we multiply the second equation by -2 we can eliminate the c variable. Multiplying the second equation by -2 changes only that equation, making the "new" system:
2c + 3b = 16.50
-2c - 4b = -19.00
When we add straight down each column, the c's cancel each other out (they subtract away) and in the b column we have -1b, and in the answer column, we have -2.50.
That equation is -b = -2.50 or b = 2.50
A bowl of soup costs $2.50, choice B

What is an equation of a line?The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
Example:
The slope of the line y = 2x + 3 is 2.
The slope of a line that passes through (1, 2) and (2, 3) is 1.
We have,
Slope = (d - b) / (c - a)
Where (a, b) and (c, d) are the two points.
Now,
The slope between (-10, -12) and (-8, -8) is 2.
The slope between (-8, -8) and (-6, -4) is 2.
The slope between (-6, -4) and (-4, 0) is 2.
Therefore,
The slope of the line passing through these points is 2.
The slope between (-4, 2) and (0, 1) is -1/4.
The slope between (0, 1) and (4, 0) is -1/4.
The slope between (4, 0) and (8, -1) is -1/4.
Therefore,
The slope of the line passing through these points is -1/4.
The slope between (-7, -7) and (0, -8) is -1/7.
The slope between (0, -8) and (7, -9) is -1/7.
The slope between (7, -9) and (14, -10) is -1/7.
Therefore,
The slope of the line passing through these points is -1/7.
The slope between (-2, 2) and (0, 3) is 1/2.
The slope between (0, 3) and (2, 4) is 1/2.
The slope between (2, 4) and (4, 5) is 1/2.
Therefore,
The slope of the line passing through these points is 1/2.
The slope between (2, -11) and (4, -25) is -7.
The slope between (4, -25) and (6, -39) is -7.
The slope between (6, -39) and (8, -53) is -7.
Therefore,
The slope of the line passing through these points is -7.
The slope between (-11, -38) and (-5, -14) is 6.
The slope between (-5, -14) and (1, 10) is 8.
The slope between (1, 10) and (7, 34) is 6.
Therefore,
The slope of the line passing through these points is 6.
Now,
The equation in slope intercept form is y = mx + c
where m is the slope of the line and c is the y-intercept.
So,
The slope of y = -4x + 6 is -4 and the y-intercept is 6.
The equation y = -1 represents a horizontal line, so the slope is 0 and the y-intercept is -1.
To find the slope-intercept form, we can rewrite 4r + y = -1 as y = -4r - 1.
Therefore,
The slope is -4 and the y-intercept is -1.
The slope of y = 6x - 4 is 6 and the y-intercept is -4.
To find the slope-intercept form, we can rewrite -x - 4y + 8 = 0 as -4y = x - 8, then divide both sides by -4 to get y = (-1/4)x + 2.
Therefore,
The slope is -1/4 and the y-intercept is 2.
To find the slope-intercept form, we can rewrite 2r - 12y + 10 = 0 as 12y = 2r + 10, then divide both sides by 12 to get y = (1/6)r + 5/6.
Therefore,
The slope is 1/6 and the y-intercept is 5/6.
Thus,
The slope and the y-intercept are given above.

Hope it helps ⭐⭐⭐An electronics company finds that 5 out of 75 capacitors produced are damaged. How
many damaged items can they expect if the company produces 1,500 capacitors?
=============================================
Explanation:
5/75 = 1/15 means that 1 out of every 15 capacitors are damaged.
Multiplying this with the 1500 capacitors produced, we expect about (1/15)*1500 = 1500/15 = 100 capacitors are damaged in this batch.
---------
A slightly different approach:
Saying "1 out of every 15 capacitors are damaged" means we can form the ratio
1 damaged: 15 total
Then multiply both sides by 100 so that the "15 total" jumps up to "1500 total" and we get the following
1 damaged: 15 total
100*(1 damaged): 100*(15 total)
100 damaged: 1500 total
We get the same answer as before.
Keep in mind that it's not a guarantee that we'll find 100 damaged capacitors out of 1500 total, but rather this is an estimate based on the average. So instead of saying "there are 100 damaged capacitors" it would be better to say "there are expected to be about 100 damaged capacitors".
100 items can they expect if the company produces 1,500 capacitors.
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
An electronics company finds that 5 out of 75 capacitors produced are damaged.
So, if there are 1500 capacitors then the damaged one are
= 5/ 75 x 1500
= 5 x 20
= 100 capacitors

Divide the coefficient of x (3) on both sides, 3x/3 = 10/3 - then divide the three and the three to get 1 (which stays as x) and then divide ten by three or just leave it as an improper fraction (this all depends on what your teacher's preference) and then you will get the final answer of x = 10/3 or x = 3.3.
