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

Answer:

Your solution is (-10, 6).

Step-by-step explanation:

Combining the equations is also known as substitution. This is done when you substitute one variable into another equation.

-5x + y = 56

x + y = -4

Let's change the second equation into one with one variable on each side.

y = -x - 4

Now, plug this into your first equation.

-5x + (-x - 4) = 56

Distribute the + sign.

-5x - x - 4 = 56

Combine the like terms.

-6x - 4 = 56

-6x = 60

Isolate x by dividing both sides by -6.

x = -10

Now plug this back into either equation.

-10 + y = -4

Add 10 to both sides to find y.

y = 6

Your solution is (-10, 6).

Check this by plugging in these values into the equation you have not checked yet.

-5(-10) + (6) = 56

50 + 6 = 56

56 = 56

Your solution is correct.

Hope this helps!

Answer:

x=-10; y=6

Step-by-step explanation:

combine the equations:

-5x + y + x + y = 56 +(-4)

-4x + 2y = 52

add 4x to each side

2y=52+4x

divide by 2

y=26+2x

now substitute 26+2x for y in the second equation:

x + 26 + 2x = -4

3x + 26 = -4

3x = -30

x = -10

therefore y = 6

Step-by-step explanation:

The inscribed angle is half the measure of its intercepted arc, that is

3x + 5 = 0.5 × 46 = 23 ( subtract 5 from both sides )

3x = 18 ( divide both sides by 3 )

x = 6

Answer:

x = 6

Step-by-step explanation:

The inscribed angle is half the measure of its intercepted arc, that is

3x + 5 = 0.5 × 46 = 23 ( subtract 5 from both sides )

3x = 18 ( divide both sides by 3 )

x = 6

Answer:

1) 3+4.50x = total cost

2) continuous, because x will be the continuous change depending on the pounds

Step-by-step explanation:

The equation to model the situation is C(w) = 3 + 4.50w, and the domain is continuous because weight (w) can take any real number value for the package.

1. The equation to model this situation can be written as follows:

Total Cost (C) = $3 (Cost of the box) + $4.50 per pound (Weight of the package in pounds)

Let's denote the weight of the package in pounds as "w." The equation is:

C(w) = 3 + 4.50w

2. The domain in this situation is continuous. The weight of the package (w) can take any real number value, and the cost function C(w) is valid for all real values of weight. There are no restrictions or gaps in the possible values of weight, meaning it is continuous.

In summary, the equation to model the situation is C(w) = 3 + 4.50w, and the domain is continuous because weight (w) can take any real number value for the package.

Step-by-step i just know

=============================================

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.

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
