quester [9]

Answer:

The cost of each chicken sandwich is $2.19 and the cost of each small orders of fries is $1.15.

Step-by-step explanation:

Given:

The cost of three chicken sandwiches and two small orders of fries is $8.87. And the cost of five chicken sandwiches and four small orders of fries is $15.55.

Now, to find the cost of each chicken sandwiches and each small orders of fries.

Let the cost of each chicken sandwich be $x.$

And let the cost of each small orders of fries be $y.$

So, the total cost of three chicken sandwiches and two small orders of fries:

$3x+2y=8.87$ ......(1)

Now, the total cost of five chicken sandwiches and four small orders of fries:

$5x+4y=15.55$ .......(2)

Now, to solve the equations by using elimination method:

$3x+2y=8.87$ ....(1)

$5x+4y=15.55$ .....(2)

So, multiplying equation (1) by 2 we get:

$6x+4y=17.74$

And, then subtracting equation (2) from the resulting equation (1):

$(6x+4y)-(5x+4y)=17.74-15.55\\\\6x+4y-5x-4y=2.19\\\\6x-5x+4y-4y=2.19\\\\x=2.19.$

The cost of each chicken sandwich = $2.19.

Now, substituting the value of $x$ in equation (1):

$3x+2y=8.87\\\\3(2.19)+2y=8.87\\\\6.57+2y=8.87$

Subtracting both sides by 6.57 we get:

$2y=2.3$

Dividing both sides by 2.3 we get:

$y=1.15.$

The cost of each small orders of fries = $1.15.

Therefore, the cost of each chicken sandwich is $2.19 and the cost of each small orders of fries is $1.15.

Answer:

you need to width x height x length b

Step-by-step explanation:

Length, width, and height are measurements that allow us to indicate the volume of geometric bodies. The length (6 cm) and the width (10 cm) correspond to the horizontal dimension. On the other hand, the height (5 cm)refers to the vertical dimension.

Identify the equation that describes the line in slope-intercept form. slope = 2 , point (- 1, 2) is on the line

JulijaS [17]

Answer:

$y=2x+4$

Step-by-step explanation:

Given a slope and a point on the line, you can use point slope form and then rearrage your terms into slope-intercept form

SLOPE-INTERCEPT FORM: $y=mx+b$ , where "m" is your slope and "b" is your y-intercept
POINT-SLOPE FORM: $(y-y_{1}) =m(x-x_{1})$ , where $y_{1}$ represents the y-coordinate of your point, $x_{1}$ represents the x-coordinate of your point, and $m$ represents the slope
